A deterministic simulation study of embryo marker-assisted selection for age at first calving in Nellore (Bos indicus) beef cattle
Provedor de dados: 74
Autores: Rosa,Artur J.M.; Bijma,Piter; Oliveira,Henrique N.; Lôbo,Raysildo B.; van Arendonk,Johan A.M.
We used deterministic simulation of four alternative multiple ovulation and embryo manipulation (MOET) closed nucleus schemes to investigate the benefits of using marker-assisted selection (MAS) of Nellore (Bos indicus) beef cattle embryos prior to transplantation to reduce the age at first calving (AFC). We found that MAS resulted in increased genetic gain as compared to selection without AFC quantitative trait loci (AFC-QTL) information. With single-stage selection the genetic response (GR) increased as follows: GR = 0.68% when the AFC-QTL explained 0.02 of the AFC additive genetic variance (sigma2A); GR = 1.76% for AFC-QTL explaining 0.05 sigma2A; GR = 3.7% for AFC-QTL explaining 0.1 sigma2A; and GR = 55.76% for AFC-QTL explaining 0.95 sigma2A.

The growth hormone 1 gene (GH1) is a candidate gene for body weight and weight gain in cattle since it plays a fundamental role in growth regulation. We investigated the GH1 gene AluI and DdeI restriction enzyme polymorphisms, located 149 bp apart in the cattle genome, as possible markers of the production potential of Canchim crossbreed cattle, a 5/8 Charolais (Bos taurus) and 3/8 Nelore (Bos indicus) breed developed in Brazil, by evaluating the birth weight, weaning weight, yearling weight and plasma insulin-like growth factor-1 (IGF-1) concentration of 7 month to 10 months old Canchim calves (n = 204) of known genealogy and which had been genotyped for the AluI and DdeI markers. Our results showed significant effect (p &lt; 0.05) between the homozygous...

Relative contribution of effects included in contemporary groups for adjusted and actual 120-day and 210-day weights in Nelore cattle in Brazil
Provedor de dados: 74
Autores: Pascoa,Lillian; Reyes,Arcadio de los; Elzo,Mauricio A.; Ferreira,Jorge L.; Bezerra,Luiz A.F.; Lôbo,Raysildo B.
The objective of this research was to estimate the relative magnitude of effects included in contemporary groups (CG) and their interactions with adjusted and actual 120 d and 210 d weights in 72, 731 male and female Nelore calves born from 1985 to 2005 in 40 herds from PMGRN (Genetic Improvement Program of Nelore). Ten models with different CG structures were compared. The analyses were done using the general linear models (GLM) procedure run in SAS software. All of the effects included in the CG for each model were significant (p &lt; 0.001) for the four traits analyzed. Inclusion of semester or trimester of birth as part of a CG was more appropriate than its use as an independent effect in the model because it accounted for interactions with the other...

The genetic diversity of 277 nucleotides in the mitochondrial DNA control region (nt 15,964 to 16,240 in reference sequence) was analyzed in crossbreed beef cattle (Brangus-Ibage, 5/8 Bos primigenius taurus x 3/8 Bos primigenius indicus) as well as in some Nellore samples (B. p. indicus). Fifty-seven mutations were found in Brangus-Ibage comprising 18 haplotypes (haplotype diversity, h = 0.851 ± 0.041 and nucleotide diversity, ntd = 0.009 ± 0.006) and 66 in Nellore (h = 1.00 ± 0.27, ntd = 0.014 ± 0.012). These data indicated sequence identities of 99.6 and 92.1% between the B. p. taurus' reference sequence and Brangus-Ibage and Nellore, respectively. The comparison of our data with sequence data for 612 individuals recovered from GenBank showed a total of...

Autores: Campêlo,José Elivalto Guimarães; Lopes,Paulo Sávio; Torres,Robledo de Almeida; Silva,Luiz Otávio Campos da; Euclydes,Ricardo Frederico; Araújo,Cláudio Vieira de; Pereira,Carmen Silva.
The aim of this investigation was to study the influence of maternal effects on the genetic evaluation of sire production in Tabapuã beef cattle. Single and multiple trait analyses were done with adjusted animal weights at 120, 240 and 420 days of age. Antagonism was observed between additive direct and maternal genetic effects, with the maternal effect being higher until weaning. The inclusion of maternal effects in the models removed part of the additive variance only in single trait analyses and resulted in smaller means and standard deviations for the sire breeding values. The use of maternal effect associated with single or multiple traits may affect sire ranking. The contradictory results of the single and multiple trait analyses for additive direct...

Genetic analyses of days to calving and their relationships with other traits in a Canchim cattle herd
Provedor de dados: 74
Autores: Mucari,Talita Buttarello; Alencar,Maurício Mello de; Barbosa,Pedro Franklin; Barbosa,Rogério Taveira.
Heritabilities and genetic correlations in a Canchim beef cattle herd were estimated using data on the following traits: male scrotal circumference at twelve months (SC12); days to first calving (DFC) for heifers; days to calving (DC) for cows; male and female weight (W) at twelve months (W12); heifer weight at the start of the first breeding season (WFBS) and at first calving (WFC); and cow weight at the start of the breeding season (WBS) and at calving (WC). Analyses of the DFC and DC traits were carried out excluding and including penalized (DFC P and DC P) non-calving females. The restricted maximum likelihood method was used, applying one-trait models for the DFC and DC analyses and two-trait models for analyses of DFC and DC combined with the other...

Autores: Silva,Ana Mary da; Alencar,Maurício Mello de; Regitano,Luciana Correia de Almeida; Oliveira,Márcia Cristina de Sena; Barioni Júnior,Waldomiro.
Resistance of beef cattle heifers to the cattle tick Boophilus microplus was evaluated by artificial infestation of 66 beef cattle heifers of the following genetic groups: 16 Nelore (NE), 18 Canchim x Nelore (CN), 16 Angus x Nelore (AN) and 16 Simmental x Nelore (SN). The animals, with a mean age of 16.5 months, were maintained with no chemical tick control in a Brachiaria decumbens pasture. Four artificial infestations with 20,000 B. microplus larvae were carried out 14 days apart and from day 18 to day 22 of each infestation the number of engorged female ticks (&gt; 4.5 mm) was counted on the left side of each heifer. Data were analyzed as the percentage of return (PR = percentage of ticks counted relative to the number infested), transformed to (PR)¼,...

Autores: Mezzadra,Carlos Alberto; Melucci,Lilia Magdalena; Corva,Pablo Marcelo; López Valiente,Sebastián; Rípoli,María Verónica; Lirón,Pedro; Giovambattista,Guillermo.
The influence of cytoplasmic inheritance on birth and weaning weight was evaluated in an experimental Hereford herd. Data on 1,720 records for birth and weaning weights from calves born between 1963 and 2002 were studied. Variance components were estimated using MTDFREML procedures and an animal model was fitted for each trait. Direct and maternal additive effects and permanent environment and maternal lineage effects were treated as random, while year and month of birth, age of dam and sex of the calf were treated as fixed. Identification of maternal lineages was based on pedigree information. The contribution to phenotypic variance of cytoplasmic lineages defined by pedigree information was negligible for both traits. Mitochondrial genotypes of cows...

The activity of the calpains/calpastatin proteolytic system is closely related to the postmortem tenderization of meat. We investigated the association between beef tenderness and single nucleotide polymorphism (SNP) markers on the CAPN1 gene (SNP316, alleles C/G; SNP530 alleles A/G) and the CAST gene 3' untranslated region (SNP2870, alleles A/G). We sampled nine slaughter groups comprising 313 steers which had been reared in beef production systems in Argentina between 2002 and 2004 from crosses between Angus, Hereford and Limousin cattle. Minor allele frequencies for the markers were 0.27 to 0.46 (C), 0.02 to 0.18 (A), and 0.24 to 0.53 (A), respectively. The presence of CAPN1 markers had significant effects on meat shear force but no detectable effects...

Leptin, thyroglobulin and diacylglycerol O-acyltransferase play important roles in fat metabolism. Fat deposition has an influence on meat quality and consumers' choice. The aim of this study was to determine allele and genotype frequencies of polymorphisms of the bovine genes, which encode leptin (LEP), thyroglobulin (TG) and diacylglycerol O-acyltransferase (DGAT1). A further objective was to establish the effects of these polymorphisms on meat characteristics. We genotyped 147 animals belonging to the Nelore (Bos indicus), Canchim (5/8 Bos taurus + 3/8 Bos indicus), Rubia Gallega X Nelore (1/2 Bos taurus + 1/2 Bos indicus), Brangus Three-way cross (9/16 Bos taurus + 7/16 Bos indicus) and Braunvieh Three-way cross (3/4 Bos taurus + 1/4 Bos indicus)...

Autores: Souza,Fabio Ricardo Pablos de; Vozzi,Pedro Alejandro; Vila,Reginaldo Aparecido; Boligon,Arione Augusti; Galerani,Marli Aparecida Vani; Lobo,Raysildo Barbosa; Martelli,Lucia Regina.
MUC1 is a heavily glycosylated mammalian transmembrane protein expressed by mucosal secretory tissues for both protection against microbial infection and lubrication. An important characteristic of MUC1 is its variable number of tandem repeats (VNTR) containing several sites for O-glycosylation. VNTR length has been associated with many human diseases and with certain economically important traits in domestic ruminants. The aim of the present study was to correlate the length of MUC1 gene VNTR with expected progeny differences (EPDs) obtained for growth, fertility and carcass traits. Five alleles were identified, with alleles containing short VNTRs being more frequent than those with long, thereby demonstrating that Brazilian Nelore cattle are...

Autores: Pereira,Andréa Pozzi; Alencar,Maurício Mello de; Oliveira,Henrique Nunes de; Regitano,Luciana Correia de Almeida.
The Canchim beef cattle (5/8 Charolais + 3/8 Zebu) has been selected for meat production in Brazil since late 1950. In the present work the effects of growth hormone (GH) and insulin-like growth factor 1 (IGF-1) polymorphisms were investigated in 688 animals born between 1998 and 2000. These animals belonged to two genetic groups, i.e., traditional and new lineages. Genotype effects on expected breeding values for birth weight (BW), weaning weight (WW) and yearling weight (YW) were investigated by the least square method. Significant effects were found for GH genotype on YW (p &lt; 0.05), with positive effects associated with the LV (leucine/valine) genotype. For IGF-1 genotypes, significant effects were found on BW (p &lt; 0.01) and YW (p &lt; 0.01)....

Autores: Diaz,Iara Del Pilar Solar; Oliveira,Henrique Nunes de; Bezerra,Luis Antônio Framartino; Lôbo,Raysildo Barbosa.
Records from 75,941 Nelore cattle were used to determine the importance of genotype by environment interaction (GEI) in five Brazilian states. (Co)variance components were estimated by single-trait analysis (with yearling weight, W450, considered to be the same trait in all states) and multiple-trait analysis (with the record from each state considered to be a different trait). The direct heritability estimates for yearling weight were 0.51, 0.39, 0.44, 0.37 and 0.41 in the states of Goiás, Mato Grosso, São Paulo, Mato Grosso do Sul and Minas Gerais, respectively. The across-state genetic correlation estimates between Goiás and Mato Grosso, Goiás and Minas Gerais, São Paulo and Minas Gerais, and Mato Grosso do Sul and Minas Gerais ranged from 0.67 to 0.75....

A deficiência de absorção do mineral da dieta é um elemento importante nas estimativas de exigências nutricionais. A eficiência de absorção de um determinado mineral pode variar com fatores ligados ao animal (características genéticas, estádio fisiológico e taxa de crescimento e outros) e pela capacidade da dieta em disponibilizar o nutriente em questão (relacionada principalmente com a forma química e associações estruturais na planta). Outros nutrientes (proteínas, energia, demais minerais) e faores antinutricionais (Glicosídeos cianogênicos, oxalato), dependendo das quantidades presentes, podem interagir com o mineral e alterar sua eficiência de absorção e sua retenção pelo animal. Alguns desses aspectos serão abordados nesta revisão.

Pastagem degradada e, atualmente, o maior problema dos sistemas de produção de bovinos no Brasil Central. Estima-se que 80% dos quase 50 milhões de hectares da área de pastagens na região de Cerrados apresentam algum estádio de degradação. O Governo do Estado de Goiás, sensibilizado com o problema. resolveu, por intermédio da Secretaria de Agricultura, Pecuária e Abastecimento mobilizar esforços para elaborar um programa de recuperação de 2.000.000 de hectares de pastagens. O objetivo desse trabalho e uma avaliação "ex-ante" do impacto bioeconômico de duas alternativas de recuperação, visando a facilitar o desenvolvimento de políticas e tomadas de decisões. A analise foi desenvolvida a partir da simulação de um sistema produtivo de gado de corte,...

Autores: ABREU, U. G. P. de; CEZAR, I. M.; TORRES, R. de A.
O cenário futuro da bovinocultura de corte indica claramente a necessidade de avanço dos sistemas de produção em direção da intensificação. Neste contexto, um dos primeiros passos para aumentar a eficiência no sistema de cria de bovinos de corte é a adoção do período de monta (PM), Entretanto, torna-se importante avaliar o impacto produtivo e econômico dessa tecnologia no sistema de produção como um todo. Os efeitos da implantanção de um PM são vários. Para essa análise, selecionaram-se os seguintes efeitos: (a) redução da taxa de mortalidade de bezerros de 10% para 4%; (b) redução touro: vaca de 1:25 para 1:33, isto é, de 4% para 3%; (c) aumento da taxa de natalidade das vacas de 65% para 75%; e (d) redução na mão-de-obra permanente de vaqueiros.

Autores: ENCARNAÇÃO, R. de O.; SCHENK, J. A. P.; ALVES. R. G. de O.
Os adensamentos consistem em promover, periodicamente, rodeios (agrupar o rebanho de cria), sob a hipótese de que a aproximação de touros e vacas conduz a um maior índice de prenhez. Este trabalho teve como objetivo relatar a experiência de um estudo realizado para averiguar se essa pratica tem, efetivamente, o efeito esperado, bem como relatar as dificuldades encontradas. Foi conduzido numa propriedade particular representativa do Pantanal de Rio Verde de Mato Grosso, MS, no período de 1987 a 1990. Utilizaram-se 766 vacas neloradas e 46 touros da raça Nelore, mantidos em duas invernadas (pastagem nativa) de, aproximadamente, 1.500 hectares cada, cuja lotação foi de 3 hectares/unidade animal e a relação touro/vaca foi de 1:16.

Dose única de zinco como fator moderador do estresse metabólico na desmama de bovinos de corte.
Provedor de dados: 14
Autores: MORAES, S da S.; THIAGO, L. R. L. de S.; MACEDO, M. C. M.; TORRES JUNIOR, R. A. de A.
Nos registros de fazendas de gado de corte, é notório que as maiores perdas no rebanho ocorrem no terço inicial da vida do animal. Este fato possivelmente está associado com o manejo de matrizes em pastos de baixo valor nutricional, que somado a uma suplementação mineral inadequada, predispõem os bezerros a uma deficiência subclínica de zinco (Zn). O resultado é que os bezerros produzidos nessa situação normalmente são fracos e portadores de distúrbios nutricionais que, além de influenciar os demais estados mórbidos, os tornam mais susceptíveis a doenças resultantes de um estresse prolongado. O estresse acelera o consumo de Zn e a principal conseqüência da alteração metabólica é a falta de apetite e depressão da resposta imune aos agentes agressores. A...

Uso de aditivos na dieta de bovinos de corte.
Provedor de dados: 14
Autores: NICODEMO, M. L. F.
Vários suplementos alimentares podem contribuir para o melhor desempenho dos animais em crescimento e terminação. Os aditivos podem melhorar a conversão alimentar e/ou produção (ganho de peso/leite) e/ou sanidade. Eles atuam por diferentes mecanismos, que incluem alteração da fermentação ruminal (pela maior formação de ácido propiônico, diminuição da formação de metano e redução da proteólise e desaminação da proteína dietética no rúmen), estabilização do ambiente ruminal e proteção do trato gastrointestinal dos agentes patogênicos. Ionóforos como a monensina e a lasalocida são antibióticos que alteram os padrões de fermentação ruminal, favorecendo o desenvolvimento das bactérias gram-negativas. Essas bactérias são as principais produtoras de succinato e...

Suplementação de bovinos em pastejo.
Provedor de dados: 14
Autores: THIAGO, L. R. L. de S.; SILVA, J. M. da.
Nos trópicos, o rebanho bovino convive com flutuações sazonais continuas, tanto na oferta como na qualidade das pastagens. Isso altera a curva de crescimento do animal em regime exclusivo de pastejo, refletindo em abate com idade superior aos três anos. Tal desempenho natural dos sistemas de produção de carne atendia as necessidades de mercados passados. Hoje a demanda e por animais mais precoces, que estejam aptos para o abate com idade inferior aos três anos a carcaças com peso mínimo de 225 quilos e 3 milímetros de espessura de gordura. O objetivo deste trabalho e discutir o efeito de restrição nutricional no ganho de peso de bovinos em pastejo,, e apresentar algumas alternativas para sua correção por meio da suplementação.

De um modo geral, as concentracoes de zinco nas braquiarias sao bastante baixas, nao atendendo as necessidades de bovinos em pastejo na maioria das categorias. As vacas de cria formam a categoria do rebanho mais predisposta a esse tipo de deficiencia, por seus elevados requisitos nutricionais, ao tempo que permanecem no rebanho, e por serem destinadas a elas geralmente as piores areas de pastagens. Resultados de analises de forrageiras nativas e cultivadas das areas de cerrado, realizadas no laboratorio da Embrapa Gado de Corte, demonstraram que 90% das amostras apresentaram teores de Zn abaixo do nível considerado minimo (20 ppm) para um bom desempenho animal.

Aspectos práticos para suplementação de bovinos em pastejo.
Provedor de dados: 14
Autores: THIAGO, L. R. L. de S.; SILVA, J. M. da.
Para ser competitiva, a bovinocultura de conta tropical precisa explorar melhor o pasto, corrigindo suas possíveis deficiências nutricionais com um suplemento, o que deve ser feito com muito critério e dentro de uma meta de produção bem estabelecida. Isto porque nos trópicos, ao contrário dos países de clima temperado, é possível manter os bovinos em pastejo durante todo o ano , maximizando o conceito de "boi fotossintético". Os elementos que compõem esse sistema são a energia solar (luz e calor), a planta forrageira, componente sinstetizados das substâncias orgânicas (via fotossíntese), os bovinos, componente transformador da matéria vegetal em carne (via fermentação ruminal), o solo, componente sustentador e fornecedor de elementos nutritivos, a umidade,...

Autores: COMASTRI FILHO, J. A.
Esta publicação tem por objetivo mostrar a saga dos pioneiros que iniciaram a conquista da região e todas as dificuldades enfrentadas na condução dos diferentes ciclos que fizeram parte da economia da região do Pantanal. Ciclos que iniciaram com a exploração do ouro na baixada cuiabana e ao final deste, começou o ciclo da pecuária de corte extensiva, com base na produção de bois magros e vacas de descarte, seus principais produtos econômicos. Hoje, essa pecuária de corte, a partir da incorporação de algumas tecnologias, têm oferecido cada vez mais ao mercado produtos de qualidade, principalmente bezerros para recria e engorda dentro e fora do estado, contribuindo para a economia dos Estados de Mato Grosso e Mato Grosso do Sul.

O estudo do comportamento materno-filial se torna importante por permitir classificar as ovelhas pela sua reatividade, resultando em maior sobrevivência dos cordeiros, o produto comercial da ovinocultura. Objetivou-se caracterizr as variáveis do comportamento materno de ovinos pantaneiros no período do periparto e correlacionar com as características produtivas. Foram utilizadas 27 ovelhas pantaneiras com idade média de 3,8 anos e peso corporal médio de 47 kg. As observações do comportamento ocorreram desde o início do parto até 2 horas após, quando foram registradas as seguintes observações: permanência da ovelha parturiente com o rebanho, grau de agitação durante o parto, postura corporal e tempos de latência do cordeiro para ficar em pé e para mamar....

Uso de animais na avaliação de forrageiras.
Provedor de dados: 14
Autores: EUCLIDES, V. P. B.; EUCLIDES FILHO, K.
A avaliação de forrageiras com animais sob sistema de pastejo se constitui em uma área de extrema importância para a bovinocultura de corte em todo o mundo, e em especial nos paises tropicais e subtropicais como o Brasil, que tem como característica e como vantagem econômica a produção de carne bovina fundamentada em pastagens. No entanto, para que os resultados deste tipo de avaliação sejam de utilidade pratica e se transformem em incrementos de produtividade e de eficiência bioeconômica do sistema de produção, faz-se necessário que esta seja conduzida,considerando-se a existência de dois sistemas bem definidos, quais sejam, pastagem e animal. E importante ainda, alem do entendimento dos inter-relacionamentos destes dois sistemas, conhecer as relações em...

O presente trabalho tem como objetivo caracterizar o sistema de produção de gado de corte predominante no Estado de Goiás. Em fase posterior, tendo como referência esse sistema, será proposto um sistema alternativo melhorado. As informações para caracterizar o sistema predominante (modal) foram levantadas por meio de um painel do tipo mesa-redonda que reuniu pecuaristas, técnicos e pesquisadores em Goiânia, GO, em julho de 2005 (Anexo 1). Em um processo de aproximações até se chegar ao consenso, definiram-se a estrutura de recursos e os coeficientes técnicos do sistema de produção modal. Com base nesses dados foram calculados indicadores de desempenho físico e econômico, destacando-se o custo de produção.

Autores: BARIONI, L. G.; MARTHA JÚNIOR, G. B.
Planning forage needs in beef cattle enterprises is necessary for efficient utilization of genetic and environmental resources in pastoral systems and to generate economic benefits in an environmentally sound way. Production risk evaluation is essential in feed planning for cow-calf operations in pastoral systems. The proposed method to accomplish with production risk in these systems is based on the time biological system is maintained in an acceptable state under adverse climate conditions. This is coined "buffering time". The buffering time is calculated for both animals and pasture using an energetic approach. For cows, the buffering time is the minimum period the animal takes to reach the lowest acceptable body weight. for pasture, it is period for...

Objetivos e critérios de seleção em bovinos de corte em fase de cria.
Provedor de dados: 14
Autores: CARNEIRO JUNIOR, J. M.; ASSIS, G. M. L. de.
A pecuária de corte é caracterizada pelas fases de cria, recria e engorda, que podem ser exploradas como sistemas de produção isolados ou combinados. A cria, período que compreende da cobertura até a desmama, é considerada a fase mais importante da vida dos bovinos, pois o bezerro precisa alcançar, no intervalo de 7 a 8 meses, de 25% a 50% do peso final de abate. Nessa fase, preconiza-se não só a qualidade dos bezerros, mas também a condição corporal e saúde das vacas, dos touros e das novilhas que irão substituir as vacas de descarte. O objetivo de quem investe na cria de bovinos de corte é obter de cada vaca do rebanho um bezerro pesado e saudável por ano. Para obtenção de bezerros de qualidade é necessário o investimento em três pilares essenciais: o...

Análise econômica para a pecuária de corte em pastagens melhoradas no Acre.
Provedor de dados: 14
Autores: SA, C. P. de; ANDRADE, C. M. S. de; VALENTIM, J. F.
A pecuária de corte é a atividade com maior expressão econômica do setor agropecuário do Estado do Acre, representando aproximadamente 40% do valor bruto da produção. Contudo, sistemas de produção caracterizados como tradicionais, que apresentam baixos índices zootécnicos, predominam na maior parte das pequenas, médias e grandes propriedades. Consequentemente, o setor apresenta baixa produtividade e rentabilidade e tem causado impactos ambientais negativos decorrentes de desmatamentos, que implicam em perda de biodiversidade e degradação dos solos. Observa-se que a retração da atividade é ocasionada por diversos fatores, com destaque para medidas voltadas à redução nas taxas de desmatamento, o que limita a expansão das áreas de pastagens, e para a baixa...

Levantamento de demandas de pesquisa com criadores e técnicos da raça Canchim.
Provedor de dados: 14
Autores: MARCONDES, C. R.
A partir da década de 1940, diversas raças foram desenvolvidas com o uso do cruzamento de raças zebuínas, comprovadamente adaptadas ao clima tropical, com raças europeias de maior produtividade. Nos Estados Unidos da América (EUA), por exemplo, foi desenvolvida a raça Santa Gertrudis (5/8 Shorthorn + 3/8 Zebu), por meio de cruzamento alternativo e posterior seleção massal. Em gado leiteiro, há o exemplo das raças Jamaica Hope e, no Brasil, a raça Girolando. A raça Canchim (5/8 Charolês + 3/8 Zebu) foi desenvolvida na Fazenda de Criação de São Carlos, SP (atualmente Embrapa Pecuária Sudeste), nessa mesma época (MOTTA, 1977). Considera-se que a raça Canchim foi formada com rigor científico, pois permitiu a comparação de animais 5/8 Charolês + 3/8 Zebu com...

Fichas para controle zootécnico de bovinos de corte.
Provedor de dados: 14
Autores: CORRÊA, E. S.; COSTA, F. P.; AMARAL, T. B.; CEZAR, I. M.
No Brasil, a maioria das fazendas tradicionais é conduzida de forma empirica e desorganizada, com raros estabelecimentos adotando registros ootécnicos, sanitários e contábeis. Em função isso, grande parte dos produtores não dispõe de números consistentes relativos aos parâmetros zootécnicos e econômicos de seu negócio. Com a recente criação do Sistema Brasileiro de Identificação e Certificação de Origem Bovina e Bubalina - Sisbov, torna-se premente que os produtores encontrem meios de se adaptar à nova realidade. Para isto, há necessidade de introduzir sistemas de registros, com o que seria possível melhorar o gerenciamento e, consequentemente, elevar os índices de produtividade. Com o crescimento do uso da informática, encontram-se disponiveis no mercado...

Manejo reprodutivo e sanitário para bovinos de corte do Pantanal - 1 - calendário profilático.
Provedor de dados: 14
Autores: SERENO, J. R. B.; PELLEGRIN, A. O.; ORMAY, J. N.
No Pantanal os animais são criados extensivamente em pastagens nativas, cujo manejo profilático-sanitário limita-se, basicamente, a cura do umbigo, vacinações anuais contra febre aftosa, raiva, curas e/ou tratamentos por acidentes. A carência em assistência técnica veterinária, faz com que os cuidados com os animais sejam realizados por peões, gerenciados por capatazes pouco habilitados tecnicamente para a administração de grandes propriedades, dificultando sobremaneira a implantação e/ou adoção de novas tecnologias. Com a economia globalizada, a atividade agropecuária tornou-se mais especializada e competitiva, obrigando aos seus seguimentos a utilizarem planejamento criterioso, visando ofertar produtos de qualidade a baixos preços na tentativa de...

Autores: DIAS, F. R. T.; PICOLI, J. F.; COSTA, F. P.; BUNGENSTAB, D. J.; MATSUURA, M. I. da S. F.
This chapter presents information on the main resources and emissions considered in the life cycle inventory for beef cattle production in Brazil. The beef cattle industry in Brazil was responsible for around 5 billion dollars in exports (IBGE, 2015). There are several alternatives for characterizing Brazilian beef cattle production systems. This work adopted two basic parameters: i) phases of the production cycle carried out in a production unit, i.e., in a farm; ii) level of intensification of cattle system, especially related to supplementary feeding and pasture fertilization.

Suplementação de bovinos em pastejo.
Provedor de dados: 14
Autores: THIAGO, L. R. L. de S.; SILVA, J. M. da.
Bovinos em pastejo convivem com flutuações sazonais continuas, tanto na oferta como na qualidade das pastagens. Isso altera a curva de crescimento de animais em regime exclusivo de pasto, refletindo em abate com idade acima dos três anos. Tal desempenho natural dos sistemas de produção de carne atendia as necessidades de mercados passados. Hoje a demanda e por animais mais jovens, que estejam aptos para o abate com idade inferior aos três anos e carcaças com peso mínimo de 225 quilos e 3 milímetros de espessura de gordura. O objetivo deste trabalho e apresentar alternativas de suplementação para corrigir as deficiências nutricionais das pastagens, visando sistemas mais precoces de produção de carne.

ABSTRACT: The reproductive efficiency is one of the major factors contributing to the success of beef cattle production systems. To achieve satisfatory reproductive performance, it is necessary an adequate herd management, particulary the adoption of breeding season, adequate cow nutrition and adequate body condition score, evaluation of the fertility of the bulls and adoption of suitable sire: cow ratio. Moreover, other practices can enhance female reproductive performance, such as separation of calves from their dams for a period (Shang), suckling restriction, exposition of females to bulls, and selection of the most fertile animals.

Programa Nacional de Pesquisa de Gado de Corte.
Provedor de dados: 14
Autores: EMBRAPA. Centro Nacional de Pesquisa de Gado de Corte.
O Brasil possui um rebanho bovino de cerca de 100 milhões de cabeças e, não produz carne suficiente para abastecer o mercado interno. A produção nacional de carne tem variado em função do maior abate de vacas e de preços de gado. A taxa de crescimento do rebanho varia em função dos preços. O modesto desempenho produtivo do rebanho brasileiro decorre do seu baixo potencial genetico, do baixo nível tecnológico dos sistemas de produção em uso. A baixa eficiência reprodutiva do rebanho e a elevada idade de abate dos novilhos são as principais causas da baixa produtividade da pecuária de corte. O aumento da eficiência reprodutiva e a redução da idade de abate podem ser alcançados, com praticas de manejo, profliga e alimentação do rebanho, principalmente nos...

Na produção de carne bovina são desejados modelos de sistemas que levam a uma menor idade ao abate e também a carcaças com mais atributos qualitativos desejáveis. Conhecido como novilho precoce, este modelo agrega ambas as qualidades e ainda é abrangente tanto para machos quanto para fêmeas e também quanto ao nível tecnológico necessário para sua execução. Do ponto de vista ambiental, possui características que se alinham a uma maior sustentabilidade. Por fim, observa-se o fortalecimento de iniciativas públicas e privadas de valorização do novilho precoce. Por todos estes aspectos, a Embrapa tem no novilho precoce uma referência de modelo produtivo e reconhece a importância de esforços de pesquisa, desenvolvimento e inovação para seu fomento.

Autores: PEREIRA, N. R.
As metas de atender à crescente demanda por carne no Brasil e no exterior, aumentar a renda dos produtores da pecuária de corte e ainda reduzir as emissões de gases de efeito estufa (GEE) podem se tornar realidade por meio da intensificação tecnológica. Pesquisas identificaram os tipos de sistemas de produção mais comuns em cada bioma brasileiro, segundo diferentes níveis tecnológicos. A partir de dados primários do Censo Agropecuário 2006 do IBGE, foi feito um retrato nacional da bovinocultura de corte, o que resultou numa tipologia dos sistemas de produção praticados no País.

A Embrapa Gado de Corte trabalha com modelos físicos de produção desde 1983. O último sistema implantado incluía a cria, recria e engorda de animais Nelore, sendo os machos suplementados em pasto na primeira seca e terminados em confinamento na segunda seca, com 24 meses de idade. Encerrada essa etapa, iniciou-se discussão para definir o novo sistema a implementar. Combinando duas taxas de lotação das pastagens (1,8 e 1,32 UA/ha) e diferentes estratégias de suplementação no período seco (ração concentrada e sal protéico), seis sistemas alternativos (e um sistema tradicional tomado como referência) foram então delineados e avaliados por meio de simulações com uma planilha eletrônica que permite projetar o desenvolvimento de uma fazenda em um horizonte de...

Provedor de dados: 14
Autores: MONTAGNER, D. B.; EUCLIDES, V. P. B.
A pecuária de corte brasileira é um dos pilares do agronegócio do país. Em 2013 o valor bruto da produção de carne foi de R$ 51,1 bilhões, atrás apenas do complexo soja (BRASIL, 2014). A cadeia produtiva da carne movimenta R$ 167,5 bilhões por ano, gerando aproximadamente 7,0 milhões de empregos (NEVES, 2012). Em 2013 o país produziu 9,5 milhões de toneladas de carne bovina, dos quais cerca de 7,2 milhões de toneladas foram destinadas ao mercado interno (CONAB, 2014). A pecuária leiteira é uma das atividades mais tradicionais do meio rural brasileiro e, de acordo com o último censo agropecuário (IBGE, 2006), existem no Brasil aproximadamente 5,2 milhões de estabelecimentos rurais dos quais 25% produzem leite, envolvendo cerca de cinco milhões de pessoas.

Autores: HIGA, R. H.; CARROMEU, C.; OLIVEIRA, C. C. de; ALMEIDA, R. G. de; SPERANZA, E. A.
Resumo - O presente estudo analisa a utilização de Filtros de Kalman (FK) para processamento de dados de pesagem diária de bovinos de corte utilizando um conjunto composto por pesagens diárias de 36 animais, coletados por 209 dias. Os resultados demonstram que o processamento de dados de pesagem diária com o Filtro de Kalman Polinomial (FKP) reduz o nível de ruído presente nos dados, viabiliza a extração do ganho de peso diário por animal, bem como torna factível a realização de predições do peso, por animal, 30 dias à frente. Adicionalmente, a utilização do FK não impacta a tomada de decisão no contexto do lote, uma vez que o peso médio dos animais no lote também não é afetado pelo FK.

Carne de vitelão: estudo exploratório de um mercado potencial.
Provedor de dados: 14
Autores: FEIJÓ, G. L. D.; COSTA, F. P.; FEIJO, R. M. B.
A pecuária brasileira de corte e de leite produz certa proporção de bezerros problemáticos, de baixo valor, que poderiam ter melhor aproveitamento econômico. Uma das possibilidades e a produção do vitelão, bezerro oriundo da pecuária de leite ou de corte, que ao ser desmamado recebe alimentação sólida e abatido com ate doze meses de idade. Para identificar as potencialidades de aceitação e a demanda desse produto, realizou-se um estudo exploratório em Campo Grande, MS, utilizando uma amostra não probabilística composta de clientes da casa de carnes "Arildo Carnes Especiais". A carne de vitelão foi oferecida a consumidores e em seguida aplicou-se um questionário contendo perguntas sobre pre -conhecimento, avaliação e pre-disposicao para o consumo desta....

Autores: CARNEIRO JUNIOR, J. M.
Na pecuária de corte, a criação de bezerros é a fase do processo de reprodução compreendida entre o nascimento e a apartação desses animais das matrizes. nessa etapa, é gerada a base que sustentará toda a cadeia de produção da carne bovina, ou seja, o bezerro desmamado. Entretanto, apesar de importante, por muitos anos essa etapa foi considerada a menos rentável do setor pecuário, geralmente desenvolvida por pequenos produtores e reservada aos piores pastos da propriedade.

Técnicas de manejo reprodutivo em bovinos de corte.
Provedor de dados: 14
Autores: VALLE, E. R. do; ANDREOTTI, R.; THIAGO, L. R. L. de S.
Na pecuária de corte, a exploração comercial do sistema de cria se constitui na fase do sistema produtivo, que envolve a criação e o manejo não só das matrizes bovinas e seus respectivos bezerros ate a desmama, mas também das novilhas de reposição e dos touros. Esse sistema tem por objetivo a produção de bezerros desmamados que representa a maior fonte de receita do criador. A venda de vacas descartadas e outros animais, apesar de contribuírem para a produção total, e uma fonte de receita marginal, mas também muito importante para o criador. Portanto, a viabilidade do sistema vai depender da eficácia e eficiência com que são utilizados os meios disponíveis para a otimização da produtividade. O escopo deste trabalho foi o de apresentar e discutir as...

Autores: COSTA, F. P.; FEIJO, G. L. D.; FEIJO, R. M. B.
A pecuária de corte, principal fonte de sustento do homem pantaneiro, vem perdendo rentabilidade ao longo do tempo, comprometendo assim sua sustentabilidade. Dentre as alternativas que podem contribuir para reverter este quadro, tem-se a produção e comercialização da carne de mamote (animal abatido ao redor de um ano de idade). Para avaliara a aceitação e as potencialidades do comercio dessa carne, um estudo exploratório foi realizado em Campo Grande, MS. Duas amostras de consumidores foram consideradas: uma amostra não probabilística por acessibilidade, constituída por clientes da casa de carnes "Arildo Carnes Especiais", e uma amostra aleatória estratificada por faixas de renda bruta, composta de funcionários da Embrapa Gado de Corte.

Controlpec 1.0: controle financeiro simplificado para a fazenda de pecuária de corte.
Provedor de dados: 14
Autores: COSTA, F. P.; CORRÊA, E. S.
A maioria dos produtores de gado de corte não realiza adequadamente o controle de receitas e despesas de sua atividade. Como a lucratividade da pecuária de corte tem se reduzido pela queda no preço de seus produtos e pela alta nos custos de produção, tal função tornou-se crucial para aqueles que querem se manter no negócio. Para atender essa demanda, a Embrapa Gado de Corte desenvolveu, em ambiente Excel, o Controlpec 1.0, uma ferramenta simples e de fácil utilização pelos produtores. Com base no movimento financeiro da fazenda são gerados relatórios que consolidam despesas, receitas e margens econômicas da atividade, tendo em conta o plano de contas definido pelo usuário. Os resultados são expostos para cada mês do ano e para todo o ano.

Tratamento anti-helmíntico de matrizes e de bezerros antes do desmame em sistema de produção de bovinos de corte.
Provedor de dados: 14
Autores: CATTO, J. B.; BIANCHIN, I.
O tratamento anti-helmíntico de vacas e de bezerros em sistemas produtivos de gado de corte gera controvérsias entre os parasitologistas. Os que não favoráveis à everminação apóiam-se nas vantagens da performance de rebanhos de cria quando submetidos ao tratamento. Da mesma forma, aqueles que contestam o retorno bioeconômico também se apóiam em resultados de pesquisa. Estudos sobre os benefícikos da everminação nessas categorias têm sido realizados quase que exclusivamente em países de clima frio ou temperado, mas os resultados não são conclusivos. Reinemeyer (1992), em uma revisão sobre o uso da everminação em vacas ou em bezerros, verificou que a diferença na taxa de concepção entre vacas tratadas e não tratadas variou de -7% a + 23%, e foi maior nos...

Touros melhoradores ou inseminação artificial: um exercício de avaliação econômica.
Provedor de dados: 14
Autores: AMARAL, T. B.; COSTA, F. P.; CORRÊA, E. S.
A pecuária de corte é uma atividade complexa, que envolve um grande número de variáveis. Dentre as decissões a tomar, destacam-se aquelas ligadas à área de reprodução, começando com a escolha entre monta natural e inseminação artificial. Por seu turno, diversas opções estão disponíveis em cada um desses processos. Quanto à monta natural, é preciso definir a qualidade e, consequentemente, o preço a pagar pelos touros. Na opção por inseminação, há alternativas quanto ao valor genético e preço do sêmen, além da possibilidade de realizar a sincronização de cio das fêmeas. Este trabalho discute os aspectos econômicos da decisão relacionada com o uso de monta natural ou inseminação artificial, bem como analisa o impacto no sistema de produção de variáveis, como...

Planejamento sanitário de gado de corte.
Provedor de dados: 14
Autores: ANDREOTTI, R.; GOMES, A.; PIRES, P. P.; RIVERA, F. E. B.
O sistema de produção de gado de corte, desde a preparação para a estação de monta ate a terminação dos animais, necessita de um planejamento sanitário. Esse controle, em uma primeira analise, visa a dar maior segurança econômica ao produtor, pela diminuição dos riscos de perdas na produtividade do sistema. Ao mesmo tempo, o sistema vai oferecer um produto mais seguro, do ponto de vista sanitário, para o consumidor. Portanto, a viabilidade da resposta dos investimentos no sistema de produção, com relação ao melhoramento genético e nutrição animal, vai depender da eficácia da prevenção de doenças no sistema. Este trabalho tem o objetivo de discutir a importância do planejamento sanitário nas doenças consideradas importantes, sem a pretensão de esgotar o...

Terminação de bovinos na entressafra.
Provedor de dados: 14
Autores: THIAGO, L. R. L. de S.; COSTA, F. P.
No Brasil Central, bovinos engordados a pasto apresentam bom desenvolvimento na estação das chuvas (ganhos de peso de 500 a 800 g/dia) e fraco desempenho na época seca, quando ganham pouco peso ou até o perdem, devido à baixa produção das pastagens. Esta sequência de bons e maus desempenhos resultam em avanço na idade de abate dos animais.

Importância da suplementação mineral para bovinos de corte.
Provedor de dados: 14
Autores: MORAES, S. da S.
A pecuária tem grande importância socioeconômica no Brasil, destacando-se a região Centro-Oeste que concentra um terço do rebanho nacional. Deficiências de minerais são comuns em bovinos em pastejo. Os elementos minerais deficientes nas pastagens tropicais são fósforo, sódio, cobre, cobalto, zinco, iodo e, em áreas especificas, selênio, manganês. Existe uma condição ótima de concentração e forma funcional para cada elemento no organismo, a fim de manter sua integridade estrutural e funcional, de maneira que a saúde , crescimento e reprodução mantenham-se inalterados. O requerimento mineral depende muito nível de produtividade. O aumento da taxa de crescimento, reprodução e produção leiteira aumenta os requisitos minerais. Assim, o fornecimento de minerais...

Formação de um rebanho de corte utilizando novilhas cobertas aos 15 e 18 meses de idade.
Provedor de dados: 14
Autores: CAVALCANTE, F. A.
Para criar corretamente um rebanho de corte a pasto é importante que o produtor conheça com antecedência as categorias de animais que deverão compor o seu rebanho. Este planejamento permite fazer uma previsão segura da área de pastagem necessária para a alimentação dos animais e, além disso, quando bem realizado, possibilita prever rendimentos e programar novas ações, assegurando a rentabilidade e a produtividade do sistema de produção implantado em sua área. Atualmente, muitos sistemas de produção estão trabalhando com cruzamento industrial, utilizando sêmen de raças européias em matrizes nelores, com a finalidade de obter animais mais produtivos. Uma das características das fêmeas geradas por meio do cruzamento industrial é que elas atingem a maturidade...

Provedor de dados: 14
Autores: ZIMMER, A. H.; EUCLIDES, V. P. B.; EUCLIDES FILHO, K.; MACEDO, M. C. M.
A pecuária de corte, apesar de ser um dos segmentos mais importantes da economia do Estado de Mato Grosso do Sul, desde o inicio da década de 90 vem apresentando queda na produtividade geral. Isso esta ocorrendo como conseqüência da redução da produtividade das pastagens, que por sua vez, e resultado de uma serie de fatores que vão desde a escolha da espécie forrageira e o manejo de formação ate a escolha do animal a ser utilizado. Pode-se ressaltar, no entanto, que uma das principais causas e o manejo inadequado das pastagens, em especial, no que diz respeito a pratica generalizada do excesso de lotação. O reflexo primário de tal pratica faz-se sentir na degradação das pastagens com serias conseqüências ambientais, em especial em solos mas arenosos. Do...

Autores: EUCLIDES FILHO, K.
O instrumento mais simples que o melhorista tem, a sua disposição, para melhoria da produção de gado de corte e a seleção individual. Seleção nada mais e que o processo de escolha de indivíduos que serão pais na próxima geração. Esta escolha pode ser efetuada selecionando-se aqueles indivíduos superiores para a característica de interesse dentro do próprio rebanho, ou ainda, entre indivíduos provenientes de rebanhos diferentes. No primeiro caso, atenção especial deve ser dada no sentido de se evitar os problemas que surgem como resultado do aumento da consanguinidade. O sucesso desta seleção esta na dependência da qualidade e variabilidade genética, permitir, em muitos casos, a utilização de reprodutores melhores do que aqueles produzidos na própria...

Autores: OLIVEIRA, G. P. de; MATSUMOTO, T.; OLIVEIRA, M. C. de S.
0 controle efetivo da dermatobiose pode ser feito por meio de dois tipos de tratamentos: estratégico e tático. Como foi visto, dois fatores são considerados importantes na exacerbação da D. hominis \te seus veiculadores, a temperatura e a umidade. Em nossa região, a temperatura inicia o seu limiar favorável a biologia dos insetos logo após o inverno, quando começa a se elevar. Na mesma época, reiniciam-se as precipitações pluviais, condicionando a atmosfera com alto teor de umidade. É fim de setembro e inicio da primavera, período em que acontece a eclosão dos insetos. Nessa época, como os dados experimentalmente obtidos indicam, acontecem as maiores infestações de berne (setembro e outubro). Devido a tal condição, sugere-se o tratamento estratégico de...

Com o avanço da produção de bovinos de corte, as exigências nutricionais aumentaram e novos microelementos minerais e formas de suplementação entraram no cenário da produção de bovinos de corte. Elementos minerais, como cromo e níquel, vem sendo estudados. O efeito da suplementação de cromo para bovinos tem se destacado nos últimos tempos, como eficiente em situações de estresse. o níquel mostrou-se eficiente em dietas com baixo teor de proteínas. Estudos experimentais destacaram o arsênio como essencial para caprinos. Elementos minerais quelatados são aqueles fixados com moleculas orgânicas de baixo peso molecular, cuja absorção e mais efetiva. Embora alguns resultados experimentais mostraram-se promissores, o uso onera o custo do sal mineral. Estudos...

Autores: MORAES, S. da S.
Deficiências e desequilíbrios minerais em bovinos são descritas em quase todas as regiões do mundo. Os elementos minerais comumente deficientes para bovinos com dieta exclusiva de pasto são: P, Na, I, Cu, Co, e Se. Em algumas regiões sob condições especificas, Ca, Mg e Mn. Por outro lado, Fe e Mn estão, normalmente, em excesso nas regiões do Cerrado Central do Brasil e Pantanal. A ingestão de dietas deficientes ou desequilibradas de elementos minerais torna mais difícil a manutenção de concentrações ótimas nos tecidos . No inicio, causa lesões bioquímicas que induzem a trocas nas formas de funcionamento, concentração e atividade do elemento nos fluidos e tecidos do corpo. Essas alterações diferem conforme os elementos e suas funções, com o grau de duração...

O confinamento e uma atividade que possibilita o abate de animais jovens e bem acabados, proporcionando, em geral, carcaças e carne de melhor qualidade. Considerando-se que, no Brasil, ainda não se pratica a adequada remuneração pela qualidade das carcaças e da carne e o concentrado e um dos itens que mais onera os custos operacionais de um confinamento a determinação de um nível ótimo de concentrado, que proporcione uma carcaça com um acabamento mínimo, e uma maneira do produtor conseguir maior produtividade nesta atividade. Foi desenvolvido, no Centro Nacional de Pesquisa de Gado de Corte (CNPGC) da Empresa Brasileira de Pesquisa Agropecuária (EMBRAPA), um experimento com animais da raça Nelore e outro com animais F1 Pardo Suíço-Nelore, visando a...

Bovine &amp;#956;-calpain (CAPN1) gene polymorphisms in Brangus and Brahman bulls
Provedor de dados: 46
Autores: Soria,LA; Corva,PM; Huguet,MJ; Miño,S; Miquel,MC.
The bovine CAPN1 gene encodes the large subunit of &amp;#956;-calpain, which is thought to be one of the most important enzymes involved in postmortem beef tenderization. Three SNPs in CAPN1 (SNP 316, SNP 530 and SNP 4751) have been associated with beef tenderness in different beef cattle breeds. The objective of this work was to implement genotyping strategies for CAPN1 markers as part of a project pursuing the identifi cation and validation of molecular markers associated with bovine meat quality and composition. Three PCR-RFLP methods were designed to determine genotypes of 64 bulls (11 Angus, 43 Brangus and 10 Brahman). Unexpected patterns resulting from the PCR-RFLP analysis at SNP 316 and SNP 530 were resolved by cloning and sequencing and lead to...

In einem im Jahr 2003 unter überdurchschnittlich trockenen und warmen Bedingungen durchgeführten Weideversuch mit drei Gruppen von jeweils 20 Jungrindern wurde die Wirkung einer biologischen (Duddingtonia flagrans) und einer medikamentösen (Paratect Flex-Bolus; PFB) Kontrollmethode gegen Befall mit Magen-Darm-Nematoden (MDN) gegenüber einer unbehandelten Kontrollgruppe verglichen. Die meteorologischen Bedingungen führten über direkte (reduzierter Übergang der Infektionsstadien auf die Vegetation; erhöhte Absterberate) und indirekte Faktoren (geringere Besatzdichte, Zufütterung) zu einer deutlichen Verringerung des Infektionsdruckes auf den Versuchsweiden. Daher erwiesen sich weder die medikamentöse noch die biologische Prophylaxestrategie als erforderlich,...

The organic unit at ADAS Redesdale was established to evaluate the physical and financial implications of converting a progressive hill/upland unit to an organic system. Conversion of 400 ha, 600 breeding ewes (in 3 flocks) and 35 suckler cows was completed in 1993. One organic flock (Organic Dipper ) was managed as a direct comparison with a conventionally managed system (Conventional Dipper).  During the early years following conversion, an organic system was developed which, financially, enabled the organic unit to compete favourably with a comparable conventional system. This was on the basis of maintaining similar stocking rates, and pushing the organic system towards maximum output.  As the experiment progressed, it became increasingly clear that a...

Biologische Helminthenkontrolle bei Weidetieren mit nematophagen Pilzen
Provedor de dados: 21
Autores: Hertzberg, Hubertus; Larsen, Michael; Maurer, Veronika.
Die Kontrolle gastrointestinaler Nematoden bei Weidetieren basiert seit fünf Jahrzehnten nahezu ausschließlich auf dem Einsatz von Anthelminthika. Die derzeit vor allem bei den Schaf- und Ziegennematoden weltweit zunehmende Resistenzproblematik erfordert die Entwicklung neuer, innovativer Kontrollstrategien, wobei die biologische Bekämpfung auf der Basis nematophager Pilze den derzeit erfolgversprechensten Ansatz darstellt. Erste Versuche zur Anwendung dieser Pilze bei Pflanzen und Tieren erfolgten bereits in den 30er Jahren, doch erst in den 90er Jahren führten Experimente zur Prüfung der Passagefähigkeit einzelner Spezies durch den Magen-Darm-Trakt von Rindern zur Isolation von Duddingtonia flagrans, womit ein maßgeblicher Fortschritt erzielt wurde....

Influence of gentle touching applied few weeks before slaughter on avoidance distance and slaughter stress in finishing cattle
Provedor de dados: 21
Autores: Probst, Johanna K.; Hillmann, Edna; Leiber, Florian; Kreuzer, Michael; Spengler Neff, Anet.
The present study investigated the effect of gentle touching applied during the last 5 weeks before slaughter in finishing cattle on behaviour towards humans, stress indicators and beef quality. Three Experiments were carried out. Experiments 1, 2 and 3 employed eight Limousin crossbred bulls, eight Piemontese crossbreds (six females, two steers) and ten Limousin crossbreds (three females, seven steers), respectively. Half of the animals were equally assigned to a treatment and a control group. The treatment group consisted of a standardized gentle head-neck-region touching and started 5 weeks before slaughter and was continued once a week in experiments 1 and 2 and twice a week in experiment 3 during the following 5 weeks. Avoidance distance tests (ADT)...

Liver flukes are very successful group of parasites that can infect many different hosts including humans. They can be found in different forms and sizes, and found almost all of the world. In Denmark, two species are found. The well-known "common liver fluke" has existed in Denmark since the Vikings, but is increasing  again recently. Not so known is "the lancet fluke", which is also fascinating as it can make the ants behave like zombies.

Noch Platz für Nischen? - Bedeutung und Potential alter und gefährdeter Rinderrassen im Ökologischen Landbau
Provedor de dados: 21
Autores: Wanke, Diethild; Biedermann, G.
Not only the biodiversity of wild species, but also the diversity in livestock is declining rapidly: Out of 6.300 registered livestock breeds in the world 1.250 are endangered or already extinct. In Germany 16 out of 32 cattle breeds are endangered, while three of the most popular cattle breeds make up 92 % of the more than two million herd-book cows. Due to their adaptation to local conditions on first sight many rare and endangered cattle breeds appear to be well suited for organic farming systems, but the percentage of rare breeds on organic farms is not much higher than on conventional ones. Council Regulation (EC) No 1804/1999 on livestock production in organic farming recommends to encourage biological diversity and to favour the use of breeds which...

Organic livestock farming systems in the Massif Central: evolution (2008-2011) and analysis of the technical and economic performances and drivers
Provedor de dados: 21
Autores: Veysset, Patrick; Tauriac, R; Benoit, M.; Belvèze, J; Patout, O; Reuillon, J.-L.; Morin, E; Vallas, M.
The “Organic Farming Massif Central” hub and fifteen partners lead a program on sustainability and on the technical and economic operation of OF livestock systems in the Massif Central. This systemic and multi-year study (2008-2011) is based on data from a constant sample over four years, from 56 farms comprising four types of products: cattle and sheep, dairy and meat. Over 4 years, the technical and economic results are quite stable, and at a good level, but with great variability inter-farms. With lower labor productivity, but with a more diversified crop rotation, a good food self-sufficiency and good technical skills, the farms with the highest income get an income more than four times higher than the farms with the lowest income .

Trait Atlas: Guidelines for standardized measurements of fertility-, health- and milk records
Provedor de dados: 21
Autores: Jaeger, Maria.
2-ORG-COWS aims for an evaluation of novel functional traits and associated environmental descriptors as a prerequisite for both the implementation of organic breeding strategies for local dual-purpose cattle kept in organic pasture based production systems, and for preventive livestock health management. In consequence, the overall objective addresses both adaptation of the dual-purpose cow to pasture based systems, and vice versa adaptation of the system for improving functional (health) traits. Due to this reasons a uniform guide for recording animal welfare (health traits, behavior, fertility), production (milk and meat quality)- and environmental descriptors (feed intake and greenhouse gas emissions) has been developed.

Produktionskosten von ökologischem Rindfleisch in ausgewählten Ländern   der erweiterten Europäischen Union
Provedor de dados: 21
Autores: Zander, Dr Katrin; Deblitz, Dr Claus.
The comparison of production costs in selected West and East European countries will give a first idea of possible international trade relationships in the organic beef sector. Via selection of typical farms in five countries, it can be shown that there are lower production costs in the Czech Republic. Nevertheless they are not as pronounced as it could have been expected. Differences in labour productivity are supposed to be the main reason for that. On the other hand the prices for organic beef are much higher in the West European countries, so that for East European farmers and processors a production and export incentive does exist. But for the time being, the organic processing sector is almost completely missing. The establishment of a processing...

Antiparasitic activity of chicory (Cichorium intybus) and its natural bioactive compounds in livestock: a review
Provedor de dados: 21
Autores: Peña-Espinoza, Miguel; Valente, Angela H.; Thamsborg, Stig M.; Simonsen, Henrik T.; Boas, Ulrik; Enemark, Heidi L.; López-Muñoz, Rodrigo; Williams, Andrew R.
Increasing drug resistance in gastrointestinal (GI) parasites of livestock and concerns about chemical residues in animal products and the environment are driving the development of alternative control strategies that are less reliant on the use of synthetic drugs. An increasingly investigated approach is the use of bioactive forages with antiparasitic properties as part of the animal’s diet (nutraceuticals) or as potential sources of novel, natural parasiticides. Chicory (Cichorium intybus) is a multi-purpose crop and one of the most promising bioactive forages in temperate regions, and numerous in vivo trials have explored its potential against parasitic nematodes in livestock. However, it is unclear whether chicory can induce a direct and broad activity...

Intérêt du pâturage mixte entre ovins et bovins dans la gestion du parasitisme digestif en système d’élevage  Agriculture Biologique

Autores: H., HOSTE; J.-P., GUITARD; J.-C., PONS.
Gastrointestinal trichostrongylosis represent one of the main constraint associated with the  breeding of ruminants  on pastures  which is associated with Organic Farming. Besides the repeated use of anthelmintic treatments, the control of these parasitic infections can also be based on  an improvement of the host response and on the reduction of animal infection by decreasing the contact with infective larvae through pertinent  grazing management.   Mixed grazing between  different hosts species, particularly  between cattle and small ruminants, represents one of the method to  reduce  the infestivity of pastures.  This method is based on the relatively high specificity of  many nematode species  for one host. The  advantages and limits of mixed grazing...

Autores: Munk, Arne; Vestergaard, Mogens; Kristensen, Troels.
Sammenfattende viser resultaterne, at LIM x DH tyre kan opdrættes i et græsbaseret produktionssystem med et forholdsvis fornuftigt restbeløb. Med økologitillæg og forventet slagtepræmie i perioden 2015-2020, kan der opnås et restbeløb til dækning af stald, arbejde og risiko på cirka 1.800 kr. per dyr (ca. 3,50 kr. per dag), selv om der gives et tillæg på 800 kr. per spædkalv i forhold til prisen på en renracet DH-tyr. For LIM x DH kvier kan der opnås et restbeløb på cirka 1.400 kr. per dyr (2,70 kr. per dag). Hvis krydsningstyrene og kvierne ses under et, kan der således opnås et restbeløb på cirka 1.600 kr. per krydsningsdyr (godt 3 kr. per dag) i gennemsnit under de nævnte forudsætninger.  Med et restbeløb på 390 kr. per dyr er der ikke økonomi i at...

Autores: Leiber, Florian; Schenk, Isabel K.; Maeschli, Ariane; Ivemeyer, Silvia; Zeitz, Johanna O.; Moakes, Simon; Klocke, Peter; Staehli, Pamela; Notz, Christophe; Walkenhorst, Michael.
In response to increasing efforts for reducing concentrate inputs to organic dairy production in grassland-rich areas of Europe, a long-term study was conducted, which assessed the impacts of concentrate reductions on cows’ performance, health, fertility and average herd age. In total, 42 Swiss commercial organic dairy cattle farms were monitored over 6 years (‘Y0’, 2008/09 until ‘Y5’, 2013/14). In comparison with overall data of Swiss herdbooks (including conventional and organic farms), the herds involved in the project had lower milk yields, similar milk solids, shorter calving intervals and higher average lactation numbers. During the  first 3 project years farmers reduced the concentrate proportion (i.e. cereals, oilseeds and grain legumes) in the...

Livestock production from grasslands with improved  management compared to traditional management
Provedor de dados: 21
Autores: Leiber, Florian.
The value of traditional versus improved management systems for grassland is discussed. The set target is the persistence of the ecological, economic and social multifunctionality of grasslands and the increase of food output from these areas without increasing parallel  requirements for arable crop or energy inputs. Based on the fact that historically traditional systems were stable and sustainable in many cases, while severe damage is faced nowadays, it is argued that lot of improvement should be based on the acknowledgment of successful traditional practises. The challenge might rather be to define improvement as a contemporary development of traditional techniques. The specific role of human labour in the context of grassland management appears to be a...

In Switzerland, most of the calves from organic milk production are fattened indoors on conventional farms with concentrates. In this study, we compared organic beef  production with two conventional systems in terms of their energy demand and global warming potential. Due to the concentrate feeding in the two conventional systems  beef cattle reach the weight for slaughtering at a shorter lifespan. The organic pasture beef production had the lowest annual per animal global warming potential, but due to  slower growth rates as a consequence of lower concentrate feeding, also the highest per kg emissions. However, conclusions on the relative environmental sustainability of  the three systems need to look beyond purely LCA and take account of the high share...

Anthelmintic activity of forage chicory (Cichorium intybus) and field efficacy of ivermectin against gastrointestinal nematodes in Danish cattle
Provedor de dados: 21
Autores: Peña-Espinoza, Miguel.
Parasitism with gastrointestinal (GI) nematodes is ubiquitous in grazing cattle and its control is critical to sustain satisfactory levels of animal health, welfare and productivity. Currently, conventional parasite control strategies relying exclusively on anthelmintic drugs are severely threatened by the development of anthelmintic resistance (AR) in bovine nematodes in several countries. In Denmark, cattle farmers and their veterinarians depend largely on macrocyclic lactones (ML), mainly ivermectin (IVM), for nematode control. However, no studies have evaluated the field efficacy of IVM against GI nematodes in Danish cattle. Alternative control approaches to minimize selection for AR and that can complement the use of the still effective anthelmintics...

Maßnahmen zur Reduzierung hornbedingter Verletzungen bei der Aufstallung von Jungrindern nach der Sommerweide
Provedor de dados: 21
Autores: Rettke, Caroline; Hörning, Bernhard; Hauswald, Anja; Verhoeven, Anne; Hünting, Klaus; Kempkens, Karl.
Die Bio-Verordnung erlaubt eine Enthornung von Rindern nur mit Ausnahmegenehmigung. Dennoch sind in Deutschland die meisten Milchkühe auf Biobetrieben enthornt. Ziel der Untersuchung war ein Vergleich verschiedener Hornschutzmaßnahmen bei der Aufstallung von Jungvieh nach der Sommerweideperiode. Drei Gruppen mit je 8 Jungrindern (12 - 21 Monate) wurden verwendet (Verhaltensbeobachtungen, Verletzungsbonitierungen). Anders als in der Kontrollgruppe wiesen die beiden Gruppen mit Holzkugeln bzw. Zitzengummis auf den Hörnern keine Verletzungen auf.

Organic Beef Production - Sire Breed Comparison
Provedor de dados: 21
Autores: Fallon, Richard; Leavy, Elaine.
The results to date, from this sire breed comparison study indicate that with the contrasting Aberdeen Angus and Charolais sire breeds that is possible to achieve animal performance data comparable to well managed conventional suckler calf to beef systems (300 kg carcass for heifers in Nov and 400 kg carcass for steers in March). Similarly the responses to sire breed type, sex and date of slaughter for the organic beef animals are biologically compatible. Organic beef is produced under organic rules in response to consumer demand for organic product. The organic system contributes to the protection of the environment and animal welfare. “We have not inherited the world from our forefathers we have borrowed it from our children” (Kashmiri proverb).

Genotypenvergleich im Hinblick auf Milchleistung, Fruchtbarkeit und Gesundheitsparameter bei unterschiedlichem  Weideumfang
Provedor de dados: 21
Autores: Brügemann, Kerstin; Rübesam, Karin; Leisen, Edmund; König, Sven.
Within a pasture genetics project 540 cows with a common German Holstein sire (VG)  served as comparison group for 110 daughters of “pasture sires” from Germany suited  to grazing conditions (D) and 150 cows with a New Zealand sire (NZ). According to  the pasture amount (PA) from May to October the 22 farms were separated into three  groups. Mean yields for milk were decreasing from  20-23kg/day to 19-20kg/day when PA increased. In farms with PA of &gt;60% the pasture genetics (NZ and D) were superior. Mean fat and protein contents of the milk were generally higher for daughters of NZ sires. These cows also needed least time until mating after their first calving and were less susceptible to hock lesions and lameness. Daughters of D bulls had the most hock...

Management of trace elements and vitamins in organic ruminant livestock nutrition in the context of the whole farm system
Provedor de dados: 21
Autores: Tame, Mike.
There is a wealth of information on the vital role of trace minerals in ruminant health. This information gives some reasonable indications of the levels required by dairy and beef animals to maintain good health though there is much less information available for sheep. There is also a wealth of information available on the role played by trace elements in the major diseases of ruminants, particularly mastitis and the problem of high somatic cell counts. There is also information available on the effects of trace mineral supplementation on fertility and production. This information should be used by organic farmers and their advisors to assess trace mineral status of animals under their care and to design strategies to help ensure that the trace element...

In the Netherlands, neighbouring cattle farms have been identified based on Fasciola levels (farms with high or levels of Fasciola) to participate in the risk factor analysis. An additional objective was to validate the bulk milk samples antibodies as a diagnostic tool for the disease. It was reported that the outcomes of blood antibodies were not always in line with milk antibodies, questioning the validity of milk antibodies for Fasciola diagnosis. In Denmark, organic dairy farmers with more than 100 animals (n=372) were contacted for...

Autores: Probst, Johanna K.; Spengler, Anet.
Die Mutterkuhhaltung und andere extensive Haltungsformen zur Rindfleischproduktion auf der Weide gelten als besonders tierfreundlich. Durch den geringen Kontakt mit Menschen werden die Tiere jedoch oftmals menschenscheu. Dies Erschwert den Umgang mit ihnen in Situationen, in denen der Kontakt unumgänglich ist, und führt zu Stress bei Rindern und Menschen. Ein gutes Verständnis des Verhaltens der Rinder und die Befolgung einiger Grundregeln im Kontakt mit ihnen können den Umgang wesentlich erleichtern und entspannen. Diese Merkblatt vermittelt die Grundlagen zur Wahrnehmung und zum Lernverhalten der Hausrinder und zeigt au, wie Tierhalterinnen und Tierhalter eine positive Beziehung zu ihren Rindern gestalten können.

This chapter analyzes the sustainability of beef cattle systems of the Spanish Rangelands known as “Dehesas”. These are traditional systems of the Iberian Peninsula where native herbaceous vegetation and evergreen species of Quercus provide the basis for extensive livestock farms. These systems are considered as outstanding High Nature Value (HNV) farming systems and the most extensive agroforestry systems in Europe according to CORINE Land Cover.   Beef farms in this area show low stocking rates and a small dependence on foodstuff purchases.However, certain changes have occurred in the last decadesdue to the Common Agricultural Policy (CAP). On the one hand, some farms have become more intensified, as a way to maximize the revenues from the CAP subsidies....

Kinship breeding is recommended as an adequate breeding approach for organic farms, because breeders work with their own well adapted cow families and bulls. Therefore kinship breeding is promoted on organic farms in a project conducted in Switzerland and Germany. An often arising question is about a possible negative impact of inbreeding on animal health, performance and welfare, but there is not much and quite varying information available. Therefore, a literature study and 10 interviews with dairy cattle breeding experts were conducted to get a better knowledge on inbreeding impacts in small populations. Results: Inbreeding depressions were described for production, sperm quality and quantity, reproduction, calf vitality, longevity and calving traits...

Autores: Bapst, Beat.
Estimations of genotype by environment interactions have been carried out for Brown Swiss dairy cattle in Switzerland. Yield traits were considered as different traits in different environments. Genetic correlations were then estimated for the same trait in different environments.  First results from bivariate analyses showed that genotype by environment interactions might exist in the investigated population, especially for fat yield and protein yield. Further analyses are needed to prove genotype by environment interactions in Brown Swiss cattle in Switzerland.

Greenhouse Gas Emissions from Conventional, Agri-Environmental Scheme, and Organic Irish Suckler-Beef Units
Provedor de dados: 21
Autores: Casey, J. W.; Holden, N.M.
The problems of overproduction within the European Union countries and the environmental impact of agriculture have lead to the introduction of schemes that aim to reduce both. Beef (Bos taurus) production forms a large component of the Irish agricultural industry and accounts for more than one quarter of agricultural economic output. Recently, the European CAP (Common Agricultural Policy) has been re-evaluated to include supplementary measures that encompass the environmental role of agriculture rather than just the production role. A life cycle assessment (LCA) method was adopted to estimate emissions per kilogram of CO2 equivalent per kilogram of live weight (LW) leaving the farm gate per annum (kg CO2 kg−1 LW yr−1) and per hectare (kg CO2 ha−1 yr−1)....

When budgeting mixed farming systems, a substantial lack of nutrients can be detected in the nutrient flow chain "forage and straw input - stable - manure output". Therefore, stable balances focus on a central component of whole farm nutrient budgets for developing efficient nutrient management strategies. At the experimental farm for organic agriculture Wiesengut in Hennef, Germany, all solid mass flows for a suckler herd and a herd of beef bulls were measured. Relative balance values...

Video: Improving health in native dual-purpose cattle (2-Org-Cows)
Provedor de dados: 21
Autores: Alföldi, Thomas.
The principle of organic breeding is to adapt the cow towards the local and natural production system. The one-sided genetic selection, preferring increased milk yield, complicates feeding and management of modern Holstein genetics when confronted with the strict rules defined for organic milk production. This requires a reformulation of existing dairy cattle breeding goals, or the utilization of alternative and locally adapted breeds that historically emphasized functionality, robustness, and longevity.  In this video, Maria Jaeger and Sven König, both from the University of Kassel, explain how the characterization of pasture based production systems, novel data recording, and genetic evaluations will lead to optimized breeding programs for dual-purpose...

Sustainable organic hill and upland farming - A collaborative case study approach
Provedor de dados: 21
It is DEFRA policy is to support sustainable farming methods (including organic farming) that benefit the environment and that provide a competitive and safe food supply chain which meets consumer requirements. The development of organic farming in the hills and uplands has been under-pinned by government support during the period of conversion from conventional to organic status (e.g. the Organic Farming Scheme). For many extensively managed hill and upland organic units the move to organic production systems has not required a substantial change in farm management policy or major loss of physical output during the early years following conversion. Despite this, organic price premiums per unit output (e.g. higher price/kg for beef and lamb) have not in...

Ökologische Tierhaltung in Brandenburg  Stand und Perspektiven
Provedor de dados: 21
Autores: Trei, Gerriet; Synnatzschke, Martin; Hörning, Prof. Bernhard.
Aim of the study was to collect information about organic livestock farming in Brandenburg.  In comparison with other German states, organic farms in Brandenburg are  bigger and the soil quality is worse. Thus, beef-suckler and sheep production is more  important than dairy, pig or poultry production. Farmers mention problems with climate  (low rainfall), lack of agricultural area and problems with the marketing.

Del en: Storfe og andre drøvtyggere blir gjort til et klimaproblem til tross for at de har foredlet gras, skapt variasjon i landskapet og vært en viktig del av stoffkretsløpet i millioner av år. Driftssystem betyr mye for det totale utslippet av klimagasser fra melk- og kjøttproduksjon. Redusert utslipp av klimagasser fra storfe trenger en helhetlig tilnærming og forståelse for å unngå at utslipp flyttes til en annen sektor eller et annet land.Dagens offisielle statistikk over klimagassutslipp fra storfe gir ikke et dekkende bilde av samlede utslipp fra storfehold.

Viele Schweizer Milchviehbetriebe bringen mehr Original-Braunvieh-Blut in ihre Braunviehherden. Ziel ist es vor allem, die Robustheit der Tiere zu verbessern. Etwas tiefere Milchleistungen nehmen die Züchterinnen und Züchter dafür in Kauf. Eine vom FiBL angeregte Studie legt nun den Schluss nahe, dass man, statt einzukreuzen, genauso gut auf reine Original-Braunvieh-Tiere setzen kann.

Comparison of animal welfare on conventional and organic dairy farms
Provedor de dados: 21
Autores: Hörning, Bernhard.
Introduction:  During the last years, concern has increased concerning animal welfare at the farm level. The Associations of Organic Agriculture have elaborated minimum requirements regarding animal welfare. The aim of the study was to compare the welfare status on conventional and organic dairy farms.      Conclusions:  Concerning sample used (straw based loose housing systems), organic farms on average showed a better welfare status than conventional farms. This has also been demonstrated in other studies (for a review see Hörning, 1998). Mean points achieved in single criteria show deficiencies and therefore potential for improvements. The respective scoring systems seem to be suitable for an on-farm assessment of housing conditions and thus to...

Practices for Organic Parasite Control
Provedor de dados: 21
Parasitism is well recognized as a major challenge to the health and welfare of organic livestock. In organic small ruminant production systems, endoparasitic disease is accepted as the most important multifactorial syndrome, resulting in lack of appetite, diarrhoea, anaemia and in extreme cases, death. In organic cattle production, despite the low stocking densities and use of improved grazing management practices, helminth infections are still a significant issue. Although previous projects funded either by EC or National Governments have largely delivered the underpinning scientific research, progress in the implementation of suitable control strategies has been hindered by: i) limitations of research at farm systems level, ii) absence of clear...

Autores: Elhottová, D.; Koubová, A.; Simek, M.; Cajthaml, T.; Jirout, J.; Esperschuetz, J.; Schloter, M.; Gattimger, A.
The present field study documents substantial changes in the soil microbial community (SMC) and organic matter (SOM) in an upland pasture soil resulting from 10 years of “cattle outdoor over-wintering practice”.  Soils from a long-term investigated pasture area were compared under three different levels of cattle impact (SI – severe, MI – moderate, NI – no impact). Extended polar lipids analysis (PLA) confirmed a qualitatively new microbial community profile and a several-fold increase of the microbial biomass in the impacted soils (SI) compared to the control NI soil. The new SMC was derived from cattle intestine microorganisms, typical by increased content of archaeal phospholipid ether lipids and by new fatty acids indicative for bacterial and fungal...

Review: Towards the agroecological management of ruminants, pigs and poultry through the development of sustainable breeding programmes. II. Breeding strategies
Provedor de dados: 21

Agroecology uses ecological processes and local resources rather than chemical inputs to develop productive and resilient livestock and crop production systems. In this context, breeding innovations are necessary to obtain animals that are both productive and adapted to a broad range of local contexts and diversity of systems. Breeding strategies to promote agroecological systems are similar for different animal species. However, current practices differ regarding the breeding of ruminants, pigs and poultry. Ruminant breeding is still an open system where farmers continue to choose their own breeds and strategies. Conversely, pig and poultry breeding is more or less the exclusive domain of international breeding companies which supply farmers with hybrid...

Die arbeitsextensive Mutterkuhhaltung hat in den letzten Jahren in der Schweiz erheblich zugenommen. Der direkte Kontakt zwischen Mensch und Tier, wie er bei der Haltung von Michkühen durch das tägliche Melken stattfindet, ist in der Mutterkuhhaltung um ein vielfaches vermindert. Eine Folge davon sind oftmals sehr scheue Tiere, die nicht selten ein aggressives Verhalten gegenüber dem Menschen zeigen. Einige Studien haben bereits gezeigt, dass eine taktile Behandlung durch den Menschen das Wohlbefinden der Tiere und gleichzeitig den Umgang mit den Menschen verbessern kann (siehe z.B.: Krohn et al., 2001, Lensink et al., 2000). In der vorliegenden Studie sollten junger Kälber aus der Mutterkuhhaltung einer taktilen Behandlung unterzogen werden. Die...

Tidligere ble god fysisk helse, høy tilvekst/ytelse og god fruktbarhet ansett å være ensbetydende med at dyret hadde det bra. I dag regnes ikke dette som tilstrekkelige indikatorer. Atferd, stressmestring og ulike uttrykk for dyrs mentale tilstand står sentralt. Negative indikatorer som sjukdom og atferdsforstyrrelser må vurderes, sammen med tilstedeværelse av positive indikatorer som lek og annen trivselsatferd. Denne artikkelen omhandler i hovedsak de delene av velferdsbegrepet som omfatter trivsel og mulighet for naturlig atferd.

Beurteilung der Tiergerechtheit von Haltungsbedingungen für Mastbullen auf Praxisbetrieben
Provedor de dados: 21
Autores: Sundrum, Albert; Rubelowsky, I.
Zusammenfassung    Um die Möglichkeiten der Beurteilung von Haltungsbedingungen im Hinblick auf die Tiergerechtheit auf Praxisbetrieben auszuloten, wurden Untersuchungen auf 50 landwirtschaftlichen Betrieben durchgeführt. In den Haltungsvarianten: Vollspaltenbucht, Tiefstreu und Zweiflächenbucht (eingestreute Liegefläche plus planbefestigte Lauffläche) wurden betriebsspezifische Haltungsbedingungen mittels technischer Indikatoren erfasst. Die Indikatoren Besatzdichte, Futterplatzbreite, Buchtentiefe und Bodenbeschaffenheit wurden in ein Beurteilungskonzept (TGI-40 Protokoll) integriert. Gleichzeitig wurden Anzahl und Gründe für vorzeitige Abgänge und Todesfälle ermittelt. Ergänzend wurden Klauen der Tiere stichprobenweise nach der Schlachtung auf...

Organic red meat development in Wales
Provedor de dados: 21
Autores: Bassett, Anna.
Much of the recent expansion of organic farming in Wales in associated with red meat production. Of the 56,621 hectares that will be fully organic by 2004, probably 80% is permanent grassland (assumption from Soil Association OFFR, 2002), the majority of which will be associated with beef and lamb production. The following factors suggest that the development of a strategy (which may encompass several sub strategies) for the red meat sector in Wales, to include production, processing, retailing, and consumer awareness, is vital to minimise disruption to the developing sector:  ·  Most of the organic red meat production in Wales is new.  ·  Other regions of the UK are seeing similar increases organic red meat production.  ·  The retail market for organic...

Mit Kuhmast die Fleischimporte halbieren
Provedor de dados: 21
Autores: Meili, Eric.
Nach wie vor hat die Schweiz einen Mangel an Rindvieh-Verarbeitungsfleisch. 22 Prozent aller Schlachthälften für Verarbeitungsfleisch (Kühe) müssen importiert werden. Bei jährlich 154713 in der Schweiz geschlachteten Kühen mit  46783 t Schlachtgewicht (SG) werden also pro Jahr zusätzlich Schlachthälften von 43 973 Kühen importiert, was rund 13346 t SG entspricht. Mit der Kuhmast könnte diese Menge um mehr als die Hälfte reduziert werden.

Grenzen und Möglichkeiten der ökologischen Rindfleischerzeugung in Mecklenburg-Vorpommern
Provedor de dados: 21
Autores: Martin, . Jörg.
Beef cattle farmers (single suckling or feeder cattle) must spend special attention to aspects of breeding, management and selling to guarantee a marketable ecological beef production.  These criterions are decisive:  1. The guarantee of excellent quality of forage is the base of ecological beef production.  2. The single suckling must be adapted on habitat to produce store cattle by using combined pure-breeding and cross-breeding programmes.  3. The beef production must be adapted on forage situation of the farms to use the advantages of bulls, bullocks and heifers in production of quality beef.

Unterscheiden sich die Schädelformen von behornten und  unbehornten Kühen?
Provedor de dados: 21
Autores: Probst, Johanna K.; Kauf, P.; Ackermann, Anja; Hutter, M.; Spengler Neff, Anet.
173 skulls of Swiss Brown dairy cows (horned=65, disbudded=165) were osteometrically sized. The greatest post-orbital width and the longitudinal height of the foreheads were recorded. The shape of the frontal bone was scaled into three categories: waveform, pointed, and straight. There was no significant influence of age on skull narrowness. More narrow skulls could be observed in dehorned cows than in horned cows. Dehorned cows had more pointed skull shapes, less waveform shapes, and less straight skulls. Whether these anatomic variances affect the wellbeing of cattle and how this alteration is exactly proceeding during growth should be examined in further studies.

Das Forschungsvorhaben 2-Org-Cows sollte aufzeigen, dass auch in bedrohten Rassen zielgerichtete Zuchtarbeit und somit eine Verbesserung der funktionalen Merkmale (Parasitenresistenz, Eutergesundheit, Wiederkäu-, Fress-, Schlaf-, Aktivitäts-Verhalten) möglich ist. Eine effiziente Züchtung impliziert die Durchführung einer Zuchtwertschätzung im BLUP-Tiermodell. Zuchtwertschätzung wiederum ist nur möglich, wenn für die jeweiligen Merkmale hinreichende Erblichkeiten, insbesondere genetische Varianzen, vorliegen. Wesentlich war somit die Installation des Sensorsystems, welches durch eine Vielzahl wiederholter Messungen die Schätzung genetischer Parameter für neue Verhaltensmerkmale ermöglichte. In der doch kleinen Population der bedrohten DSN zeigte sich, dass...

Phytotherapie für Tiere – ein fast in Vergessenheit geratenes Potential?
Provedor de dados: 21
Autores: Ayrle, Hannah; Mevissen, Meike; Kaske, Martin; Nathues, Heiko; Häsler, Stephan; Walkenhorst, Michael.
Seit Jahrtausenden werden Arzneipflanzen bei Mensch und Tier angewendet. Das breite Spektrum pflanzlicher Sekundärstoffe und ihre pflanzenspezifischen Kombinationen bergen ein aktuell weitgehend ungenutztes Potential zur Behandlung kranker Einzeltiere, aber auch zur allgemeinen Verbesserung der Tiergesundheit. Neben optimierten Haltungs- und Hygienebedingungen sowie Massnahmen der Immunisierung könnte die Verabreichung von Arzneipflanzen und Naturstoffen eine Möglichkeit sein, den Einsatz von Antibiotika in der Nutztierhaltung zu reduzieren.

Ökologische Ochsenmast – leistungsgerecht und qualitätsorientiert
Provedor de dados: 21
Autores: Martin, Jörg.
In Mecklenburg-Vorpommern produzieren Ökolandwirte, wie in allen östlichen Bundesländern, sehr häufig auf ertragsschwachen Standorten mit überdurchschnittlich hohen Grünlandanteilen. Hohe Erträge sind hier im Marktfruchtbau oft nur schwer erreichbar. Den Bestrebungen nach geschlossenen Stoffkreisläufen entgegenkommend, bietet deshalb die Kopplung von Pflanzenbau und Tierhaltung eine Chance, einen höheren Veredlungsgrad zu erreichen und damit „angemessene“ betriebliche Einkommen zu erzielen.  Eine wesentliche Voraussetzung für deren Erwirtschaftung aus der tierischen Produktion sind neben hohen Leistungen vor allem hohe Produktqualitäten, unabhängig von der gehaltenen Tierart (Rind, Schaf, Schwein, Geflügel) und der Produktionsrichtung. Grundlagen dafür...

Meaningfulness of design criteria in relation to claw disorder and mortality of fattening bulls
Provedor de dados: 21
Autores: Sundrum, Albert; Rubelowsky, Ina.
To prove the meaningfulness of design criteria in relation to claw disorder and mortality of fattening bulls a cohort analysis was carried out on 50 farms with housing systems characterised by fully slatted floor, deep litter or litter+concrete floor. Hoofs of the bulls were collected after slaughtering and examined for pathological findings. Space allowance, feeding space, pen depth and quality of the floor were integrated into a TGI-40 protocol and related to the incidence of early losses.   Slatted floor pens were characterised by a low space allowance and a low pen depth. In contrast, dimensions of pens with deep litter and litter+concrete floor were clearly larger but showed a wide and overlapping variation in the different design criteria. Hoofs on...

Mehr als eine Nische? Untersuchungen zum Potential der muttergebundenen Kälberaufzucht in der Vermarktung von Milch und männlichen Kälbern
Provedor de dados: 21
In der Milchviehhaltung wird die  frühzeitige Trennung von Kuh und Kalb wiederholt von Verbrauchern und Tierschutzorganisationen kritisiert. Inzwischen praktizieren einzelne Milchviehbetriebe die muttergebundene Kälberaufzucht und die Auswirkungen des Verfahrens auf die Gesundheit und Leistung der so aufgezogenen Tiere werden verstärkt untersucht. Bisher fehlen jedoch Informationen, wie die so erzeugte Milch und die Kälber, hier insbesondere auch die männlichen, vermarktet werden bzw. welche Chancen für die Vermarktung bestehen. Ziel des Projektes ist deshalb, zum einen den Status quo der Produktion und Vermarktung von Milch und Kälbern aus der muttergebundenen Kälberaufzucht zu erheben und zum anderen Informationen zur Akzeptanz bzw.

Adding Value to Organic Milk Production Systems: opportunities for marketing meat and milk from dual purpose breeds
Provedor de dados: 21
Autores: van Diepen, Pauline.
There is growing demand for and supply of organic milk. This results in more organic steers being produced. Many organic steer calves are sold to non-organic producers or are destroyed at birth. This is a serious issue for the organic dairy sector.  This report also provides an overview of the current situation of the meat from the organic dairy sector, identifies opportunities for improving the marketing of organic dairy steer calves and provides a special focus on the use of dual-purpose breeds.  Dual-purpose breeds were more often used in the past. Some organic dairy producers have returned to using dual-purpose breeds such as the MRI (Maas Rijn Ijssel) and the Shorthorn.  Stakeholder interviews showed that the high milk price makes the dairy farmers...

Challenges and future perspectives of different organic beef cattle farms of Southern Europe
Provedor de dados: 21
Autores: Escribano, A.J.; Gaspar, P.; Mesias, F.J.; Escribano, M.; Pulido, A.F.
The livestock sector must be redesigned in order to achieve food security sustainably. Several authors have argued that organic farming may contribute positively in this sense. However, the externalities of the organic livestock systems are influenced by several factors. Due to this, the aim of this paper is to shed light on the needs and perspective of the organic beef cattle farms located in the 'dehesa' ecosystem (SW Spain). For this purpose, we created the 'Feasibility of Success Index' (FSI) by using indicators that took into account the context of the extensive livestock systems located in the Mediterranean basin. Two groups of organic farms were analyzed: farms that sold calves at weaning age a conventional ones (Organic); farms that fattened and...

Agriculture at Pwllpeiran has a long history.  Pwllpeiran was eventually established as an Experimental Husbandry Farm in 1955. During the following forty years, work at the farm achieved substantial improvements in the quality and quantity of lamb and beef produced, but by the turn of the millennium the emphasis of agricultural policy was turning away from increased livestock production per se and towards the development of environmentally sensitive farming systems.    The 1,118 ha Pwllpeiran Research Farm is now managed by ADAS Wales. The land is rented from the National Assembly for Wales and the Forestry Commission. All of the land is under a ‘whole farm’ Environmentally Sensitive Area agreement.    The results from the Pwllpeiran unit underline the...

Zusammenfassung  Analog zum Ökologischen Gesamtzuchtwert (ÖZW) für Bullen wurde Ende 2008 erstmals ein ÖZW für Kühe berechnet und den ökologischen Milchviehbetrieben in Bayern mit dem Jahresabschluss der Milchleistungsprüfung zur Verfügung gestellt. Der ÖZW unterscheidet sich vom konventionellen Gesamtzuchtwert (GZW) hauptsächlich durch die deutlich stärkere Gewichtung der Fitnessmerkmale. Während bei der Zucht nach GZW der erwartete Selektionserfolg überwiegend in der Milch- und Fleischleistung liegt, wird bei der Selektion nach ÖZW, neben einer moderaten Verbesserung der Leistung, eine deutliche züchterische Verbesserung der Fitnessmerkmale angestrebt.

This study investigated the effect of, and interactions between, US Brown Swiss (BS) genetics and season on milk yield, basic composition and fatty acid profiles, from cows on low-input farms in Switzerland. Milk samples (n = 1,976) were collected from 1,220 crossbreed cows with differing proportions of BS, Braunvieh and Original Braunvieh genetics on 40 farms during winter-housing and summer-grazing. Cows with more BS genetics produced more milk in winter but not in summer, possibly because of underfeeding potentially high-yielding cows on low-input pasture-based diets. Cows with more Original Braunvieh genetics produced milk with more (i) nutritionally desirable eicosapentaenoic and docosapentaenoic acids, throughout the year, and (ii) vaccenic and...

Nutzen und Kosten tiergerechter Milchviehhaltung – Versuch einer Bewertung verschiedener Laufstallsysteme anhand des Tierverhaltens und der Jahreskosten
Provedor de dados: 21
Autores: Hörning, Bernhard.
Animal welfare versus costs? – Assessment of dairy housing systems  Animal welfare plays an important role in organic agriculture. The EEC-regulations lead to high standards: e.g. loose housing, outside yards and pasture for cattle. Loose housing systems for dairy cows mainly differ in the design of the lying area (cubicles, bedded-sloped floor, deep litter/straw yard). In this paper, animal welfare and economic aspects of these systems are confronted. Results from own behavioural observations on 40 farms and calculations of profitability are presented. With regard to most behaviour variables obser-ved, straw yards and sloped floors proved most adequate, followed by comfortable cubic-les. Traditional cubicle houses had the most adverse effects on...

Commerce et santé des veaux «excédentaires» en zone de montagne: une étude des Grisons
Provedor de dados: 21
Autores: Janett, Rut; Oehen, Bernadette.
Il existe peu d’informations concernant la gestion des veaux en montagne. Dans cette zone d’exploitation agricole, l’élevage occupe une place importante, marquée par l’économie alpestre. Aux fins de l’étude, onze chefs d’exploitations laitières et d’exploitations d’engraissement du canton des Grisons ont été interrogés sur la santé des veaux. Leurs réponses ont été analysées à la lumière de la Theory of Planned Behavior ou TPB (théorie du comportement planifié) développée par Ajzen. Les personnes interrogées exercent le commerce des veaux principalement à l’échelle régionale. En raison de l’estivage, le commerce des veaux est saisonnier. Certains décrivent une coopération étroite entre les exploitations laitières et les exploitations d’engraissement. Cela...

Control of gastrointestinal nematodes in organic beef cattle through grazing management
Provedor de dados: 21
Autores: Hertzberg, Hubertus; Figi, Rolf; Noto, Fabio; Heckendorn, Felix.
Gastrointestinal nematodes (GIN) are a major health and economic risk factor in ruminant production in organic and conventional farms (Thamsborg et al., 1999). Fattening of organic beef cattle (OBC) on pasture is an emerging area for organic farmers in Switzerland, which partly compensates the declining development in dairy production. So far, there are no data available about the parasitic status of beef cattle kept in organic farms between weaning (4-6 month) and slaughter (24-26 month).    The aim of the present study was to assess the parasitological status of organic beef cattle in the pre-alpine and alpine region of Switzerland and to analyse the benefits of different grazing strategies for GIN control.

A sustainability assessment of organic and conventional beef cattle farms in agroforestry systems: the case of the dehesa rangelands
Provedor de dados: 21
Autores: Escribano, A.J.; Gaspar, P.; Mesias, F.J.; Pulido, A.F.; Escribano, M.
Pasture-based livestock systems are a key element for the maintenance of the dehesa ecosystem. However, adaptative changes (mainly intensification) are reducing their sustainability. As a consequence, sustainable livestock systems must be found and implemented. Due to this, this work assesses the sustainability of 63 beef cattle farms (including organic and conventional ones) with two aims: (i) to identify the most sustainable systems and; (ii) to establish management measures in order to increase farms sustainability. For this purpose, a methodological adaptation of the MESMIS Framework was applied. A cluster analysis allowed us to identify three farms typologies. Typology 1 (organic farms) had the highest scores for the sustainability index (66.75%) and...

Major organic dairy farm types in Germany and their farm,  herd, and management characteristics
Provedor de dados: 21
Autores: Ivemeyer, Silvia; Brinkmann, Jan; March, Solveig; Simantke, Christel; Winckler, Christoph; Knierim, Ute.
Organic milk production varies due to topographical and structural farm conditions, but very little information is available about this variation in Germany.  The aim of this study was to identify typical major farm types (MFTs) of German organic dairy farms and to describe their farm, herd, and management characteristics.  Based on data from 204 organic dairy farms from previous studies with representative samples, fourMFTs were identified by cluster analysis. Cluster-criteria were herd size, milk yield, region, and housing system. Identified MFTs were (A) medium-scale herds with low-tomedium milk yield, (B) small-scale herds with low milk yield, (C) large scale herds with high milk yield, and (D) medium-scale herds in Southern Germany with medium milk...

Autores: Krebs, Adrian.
Die Mutter- und Ammengebundene Kälberaufzucht (MAgKa) ist immer noch im Pionierstadium, in der Schweiz gibt es rund zwanzig Betriebe, welche die Kälber enger mit den Müttern zusammenleben und saugen lassen, während die Kühe gleichzeitig gemolken werden. Für die Praktiker überwiegen die Vorteile: Intensivere Beziehung zwischen Kuh und Kalb, fittere Jungtiere und Arbeitsersparnis. Es gibt aber auch ein paar Probleme, für die jeder Betrieb seine individuelle Lösung finden muss.

Prägende Erlebnisse zwischen Rind und Mensch
Provedor de dados: 21
Autores: Probst, Johanna.
Gerade Mutterkuhhaltung wird mit tiergerechter Haltung in Verbindung gebracht, aber leider auch vermehrt mit scheuen und teilweise sogar agressiven Tieren. Nervöses Verhalten und Stressreaktionen der Tiere entstehen meist aus Furcht vor dem Menschen. Dies beruht darauf, dass direkter Kontakt zwischen Mensch und Tier, wie er in der Milchviehaltung automatisch durch das zweimal tägliche Melken entsteht, bei extensiver Haltung wegfällt. Eine Schweizer Studie, die vom FiBL, Frick und der ETH, Zürich durchgeführt wurde, zeigte auf, dass positiver menschlicher Kontakt, durchgeführt früh im Leben von Kälbern aus der Mutterkuhhaltung (CH-Label: Natura Beef), sich sehr positiv auf ihr späteres Verhalten gegenüber Menschen auswirkt.In dieser Studie wird u.a. auch...

Gehölzfutter - eine neue Quelle für die ökologische Tierernährung
Provedor de dados: 21
Autores: Rahmann, Gerold.
Seit der Trennung von Wald und Weide, die Ende des 18ten Jahrhunderts einsetzte, wurden  Gehölze in Deutschland immer weniger als eine landwirtschaftliche Ressource betrachtet. Seit  dem Zweiten Weltkrieg ist ihre Bedeutung praktisch auf Null gesunken und sie werden  landwirtschaftlich nur noch als störend wahrgenommen. In der Konsequenz wurden vielerorts  Hecken an Feldrändern und Gehölze auf Freiflächen entfernt. Erst mit dem Bewusstsein um  die ökologische Bedeutung der Gehölze z.B. als CO2-Senke, Habitat für viele Tierarten,  Luftreinigung, Wasserhaushalt und den ländlichen Tourismus sind Gehölze wieder ins  öffentliche Bewusstsein geraten. Heute sind rund 30% des Bundesgebietes mit Wald bedeckt,  dabei sind viele mit Sträuchern und Bäumen bestandene...

Comparison of Organic and Conventional Beef-Suckler Farms in Germany
Provedor de dados: 21
Autores: Hörning, Prof. Bernhard; Feige, Martina; Dollinger, Julia.
This study aims to compare conventional and organic farms with beef-suckler herds. Addresses were collected mainly by contacting breeding associations and farmers' magazines. 216 questionnaires were evaluated (34.1% of them organic). Beef-suckler production in Germany is an extensive production system (small farms, small herd sizes, high percentage of grassland, low soil points, etc.). 39% of farms had to fulfil special regulations for extensive grassland production and 43% carried out landscape conservation measures. Farmers specialize in beef-suckler production. 60% of them are part-time farmers. Beef production amounts to two thirds of their agricultural income. Most farmers keep only beef cattle on the farms. Other farm animals are kept in small stock...

Autores: Ayrle, Hannah; Mevissen, Meike; Kaske, Martin; Vögtlin, Andrea; Fricker, Raffael; Hofmann, Bernd; Büttner, Mathias; Marinovic, Zlatko; Walkenhorst, Michael.
Bluetongue virus (BTV) antibodies were analysed in 27 Swiss calves born in 2016 at the age of 16–19 days using competitive enzyme-linked-immunosorbent-assay (cELISA) and virus neutralization test (VNT) (animal trial permission number: 75684). Obligatory documentation proved that 15 of 27 dams were BTV-8 vaccinated once or three times in 2008–2010. The offsprings of the non-vaccinated dams were seronegative. Two of three calves and 11 of 12 calves descending from dams who had been vaccinated one or three times, respectively, had BTV specific serum antibodies. As Switzerland is considered BTV-free from 2010 to 2016, it is likely that BTV-8 antibodies were transferred via colostrum. Furthermore, we confirmed neutralizing cross-reactivity of BTV-8 with BTV-4...

Alternating grazing to control parasites in young cattle (Video)
Provedor de dados: 21
Autores: Alföldi, Thomas.
Within the CORE Organic project MIX-ENABLE, Steffen Werne (FiBL) and his team are testing more sustainable ways of controlling gastrointestinal nematodes in ruminants. Farmers usually control parasites by using dewormers. However, resistance against these products is increasing. One approach is mixed grazing of different livestock species.  It is well known that sheep and goats can benefit from mixed grazing with cattle in terms of animal health and performance. This is because gastrointestinal parasites are usually specialized in one livestock species, and mixed grazing has thus a “diluting” effect.  Conversely, little is known whether young cattle can also benefit from mixed grazing with sheep.  This is what Steffen Werne and his teams want to find out...

Bio Weide-Beef ist punkto Nachhaltigkeit auf der Höhe
Provedor de dados: 21
Autores: Krebs, Adrian.
In einem FiBL-Projekt ist die Nachhaltigkeit von Bio Weide-Beef mit dem Migros-IP-Label TerraSuisse und konventioneller Rindermast verglichen worden. Die Ergebnisse basieren auf Daten von existierenden Betrieben in der Schweiz und zeigen, dass die biologische Weidemast unter Einbezug aller analysierten Faktoren am besten abschneidet. Trotzdem ist das Produktionssystem in der neuen Agrarpolitik ökonomisch unter Druck geraten.

Utvärdering av alternativa kontrollåtgärder mot betesburna parasiter hos förstagångsbetande nötkretatur
Provedor de dados: 21
Hälsa och produktivitet hos betande djur påverkas i olika hög grad av parasiter, och om infektionerna inte kontrolleras utgör de både ett djurskyddsproblem och medför ekonomiskt avbräck. Resultaten från ett nyligen avslutat SJFR-finansierat projekt visade att betesburna magtarmparasiter orsakade tillväxtförluster hos förstagångsbetande kalvar på mellan 30 och 60 kg utan att djuren visade yttre tecken på sjukdom. Vi kunde dock även visa att fullgod tillväxt uppnåddes när djuren erbjöds parasitfria beten eller då de kontinuerligt behandlades med avmaskningsmedel. Ibland är det emellertid inte tillåtet eller praktiskt möjligt att tillämpa sådana kontrollåtgärder. Sökandet efter alternativa kontrollstrategier mot betesburna parasiter måste därför ha fortsatt...

Autores: Krogmeier, Dieter; Gerber, Antonia.
Der ÖZW für Bullen für die Rassen Braunvieh, Fleckvieh und Gelbvieh ist seit vielen Jahren in der Zuchtpraxis etabliert und er ist für ökologische aber auch für interessierte konventionelle Betriebe ein wichtiges Hilfsmittel bei der Bullenauswahl. Entsprechend dem ÖZW für Bullen wurde ein ÖZW für Kühe entwickelt, der seit Ende 2008 für die ökologischen Milchviehbetriebe gerechnet wird. In Kombination ist der ÖZW für Bullen und Kühe ein wichtiges Hilfsmittel für züchterische Entscheidungen im ökologischen Milchviehbetrieb und er soll in Zukunft dazu beitragen, dass die Bedürfnisse der ökologischen Milchviehbetriebe stärker in den aktuellen Zuchtprogrammen berücksichtigt werden.

Beiteadferden på fjellbeite og innmarksbeite i lavlandet hos kyr av rasen Sidet trønder- og Nordlansfe (STN) med diekalver blei studert i tre perioder av beitesesongen. I de to første periodene, juni og juli, brukte dyra i fjellet mer tid på å gå enn de på innmarka. For de andre aktivitetene var det små forskjeller. Det var likevel en tendens til at dyra i fjellet brukte mindre tid på å beite og til å stå enn de som gikk på innmarksbeite.

Effect of starch level and roughage intake on animal perfomance, rumen wall characteristics and liver abscesses in intensively fed Frisian bulls
Provedor de dados: 21
Autores: Jorgensen, K.F.; Larsen, S.B.; Andersen, H.R.; Vestergaard, M.
Organic dairy cows in Denmark has a higher frequency of liver abscesses, which is probably due to higher starch levels in the feed rations to high yielding cows compaired to conventional cows. Following abstract is based on experiments on young bulls and demonstrates whether replacing high-starch feeds with low-starch feed, such as dried grass pellets and sugar beet pulp, can reduce the problems with liver abscessation without reducing the performance level. The low-starch feed would be relevant to organic dairy production.    In total, 41 Danish Friesian bulls (154±20 kg LW) were allocated into four treatment groups in a 2x2 factorial design fed either a high starch (N) or a high fibrous concentrate (F) and either chopped barley straw (S) or a mixture of...

Autores: Meyer-Glitza, Patrick.
Vegetarianism and Veganism have become the subject of public debate. But even a vegetarian diet including milk products results in the slaughtering of cows after their productive life and in the slaughtering of fattened male breed cattle. Narrative and semi-structured interviews were conducted on 5 farms that do not slaughter their cattle. These farms were either certified as organic farms, or are former organic farms or strongly oriented toward organic farming. Subsequently the interviews were analysed applying Grounded Theory. The emerging four principles of a care-system for healthy, handicapped, old, ill and dying cattle are described and related to the IFOAM principles. Further on innovations leading to this care-system and the main challenges it...

Autores: Steinwidder, Andreas; Starz, Walter; Rohrer, Hannes; Pfister, Rupert.
Die Futterqualitätsbestimmung ist von zentraler Bedeutung für die landwirtschaftliche Praxis, Beratung und Forschung. Da die Probengewinnung bei Weidehaltung über fistulierte Rinder belastend für die Tiere und sehr aufwändig ist, wird üblicherweise auf Futterproben aus simulierten Weideflächen oder auf Proben direkt aus der Weide zurückgegriffen. In der vorliegenden Untersuchung wurden Futterproben aus schnittgenutzten Kurzrasen-Simulationsflächen (KW-SIM) sowie Handfutterproben, direkt aus den Kurzrasenweideflächen (KW-HAND) von Milchkühen, hinsichtlich des Nährstoff- und Energiegehalts verglichen. Es zeigten sich für XP, XL, XX, ADFOM und P signifikante Gehaltsunterschiede zwischen den Probenherkünften (KW-HAND bzw. KW-SIM), wenngleich die absoluten...

Conversion of french suckler cattle farms to organic farming: adaptation of the system and its economic consequences
Provedor de dados: 21
Autores: Veysset, Patrick.
French suckler farmers need advice on the impact of the conversion to OF. To help them with their decision-making process, we constructed an LP model that optimises the farming system, taking OF constraints and nitrogen balance into account. According to the model, the shift to OF had a greater impact on a mixed crop-livestock farm system than on that of a grassland farm. As a result of the very high cost of organic N fertiliser and the necessity of maintaining the N balance, the shift to OF in the case of the mixed farm resulted in less emphasis on cereal and more emphasis on livestock. For this type of farm, a significant drop in its proportional costs due to extensification was sufficient to maintain the overall gross margin of the holding. For the...

Bedding hygiene, cleanliness and lying behaviour  for heifers housed on wood chip or straw deep  bedding
Provedor de dados: 21
Autores: Johanssen, Juni Rosann E.; Sørheim, Kristin; Strøm, Turid; Brunberg, Emma.
The aim of this project was to compare the hygienic quality of the bedding, as well as the parasitic load, cleanliness and lying behaviour in heifers kept on either straw or wood chip deep bedding. Fourteen heifers kept in two pens were housed on straw or wood chip bedding for 43 days, after which the bedding material was switched for 43 additional days. Significantly more mould was found in wood chip than in straw and there was a tendency towards less yeast in wood chip. The heifers had a low faecal parasitic load. The results indicate that the wood chip treatment resulted in somewhat cleaner animals. The heifers had a significantly longer total lying time when kept on straw. In conclusion, wood chip deep bedding could be an option as bedding material,...

Medicinal plants-prophylactic and therapeutic options for gastrointestinal and respiratory diseases in calves and piglets? A systematic review
Provedor de dados: 21
Autores: Ayrle, Hannah; Mevissen, Meike; Kaske, Martin; Nathues, Heiko; Gruetzner, Niels; Melzig, Matthias; Walkenhorst, Michael.
Background: Gastrointestinal and respiratory diseases in calves and piglets lead to significant economic losses in livestock husbandry. A high morbidity has been reported for diarrhea (calves ≤ 35%; piglets ≤ 50%) and for respiratory diseases (calves ≤ 80%; piglets ≤ 40%). Despite a highly diverse etiology and pathophysiology of these diseases, treatment with antimicrobials is often the first-line therapy. Multi-antimicrobial resistance in pathogens results in international accordance to strengthen the research in novel treatment options. Medicinal plants bear a potential as alternative or additional treatment. Based on the versatile effects of their plant specific multi-component-compositions, medicinal plants can potentially act as ‘multi-target drugs’....

Agroecology uses natural processes and local resources rather than chemical inputs to ensure production while limiting the environmental footprint of livestock and crop production systems. Selecting to achieve a maximization of target production criteria has long proved detrimental to fitness traits. However, since the 1990s, developments in animal breeding have also focussed on animal robustness by balancing production and functional traits within overall breeding goals. We discuss here how an agroecological perspective should further shift breeding goals towards functional traits rather than production traits. Breeding for robustness aims to promote individual adaptive capacities by considering diverse selection criteria which include reproduction,...

„Das, was heute für uns normal ist, dass wir uns treffen und austauschen – das gab es früher nicht!“  Das Netzwerk Ökologische Tierzucht bringt seit 2002 die Pioniere und Experten zusammen, die sich in der Ökologischen Tierzucht engagieren. Das Netzwerk (2. Projektphase 2005-2007) arbeitet in Form von tierartbezogenen Arbeitsgruppen, die ihre Ergebnisse in Workshops diskutieren. Geleitet wurden die Fachgruppen von ausgewiesenen Experten; die Koordination übernahm die Zukunftsstiftung Landwirtschaft.   Tierzucht ist als Thema auf den Betrieben und bei den Beratern oftmals weit weg. Das Potenzial, das eine artgemäße Tierzucht gerade auch für die Tiergesundheit und damit auch für die ökonomische Situation bietet, wird nicht gesehen. Das Netzwerk kann hier...

Sustainability of organic and conventional beef cattle farms in SW Spanish rangelands (‘dehesas’): a comparative study
Provedor de dados: 21
Autores: Escribano, A.J.; Mesias, F.J.; Gaspar, P.; Escribano, M.; Pulido, F.
Organic production in Spain has increased substantially in recent years due to several factors, such as the growing interest of the European Union towards preserving sensitive ecosystems; the potential role of organic production in the socio-economic development of rural areas and the growing consumers' demand for safer and higher quality foods. Within this framework, this paper analyzes the beef sector of SW Spanish rangelands (dehesas). These are traditional systems characteristic of the Iberian Peninsula where native herbaceous vegetation and evergreen species of Quercus provide the basis for extensive beef farms. Alt-hough traditional management in dehesa farms is of vital importance for the sustainability of this particular ecosystem, in the last...

Système de production de viande bovine pour les régions marginales-  Rindfleischproduktionssysteme
Provedor de dados: 21
Au cours des prochaines années, de profondes mutations sont à attendre dans le marché laitier en Suisse suite à l'abandon du contingentement laitier et à l'application des accords bilatéraux avec l'UE. De nombreuses exploitations devront abandonner la production laitière, particulièrement dans les régions périphériques qui ne bénéficient pas de produits spécifiques à forte valeur ajoutée. Sans alternative de production, une partie du mandat constitutionnel donné à l'agriculture, à savoir une occupation décentralisée du territoire et l'entretien du paysage, pourrait ne plus pouvoir être rempli. Des alternatives et/ou des compléments à la production laitière doivent par conséquent être développés, avec un accent fort sur les régions marginales.  A....

Review of the market for Welsh organic meat, 2007
Provedor de dados: 21
Autores: Cullen, Richard; Lampkin, Nic; Moakes, Simon.
The supply situation for Welsh organic meat  Organic production in Wales has been developing steadily in the last five years, with particular emphasis on organic cattle and sheep production. This was despite over-supply conditions in some sectors, notably dairy, following the very rapid growth in 1999/2000.  Between the end of 2002 and end of 2005, the number of holdings increased by 12% to 688, and the certified land area increased by 29% to 71,000 hectares, of which more than 90% is grassland. Growth in Wales has exceeded other parts of the UK, reaching 5% of agricultural land by end 2005. More rapid growth is projected for 2006 and possibly 2007.  Organic cattle and sheep numbers have also increased steadily between 2003 and 2005, with total cattle...

Als Herdentiere interagieren Rinder ständig mit Artgenossen und zeigen deshalb ein ausgeprägtes Sozialverhalten, das u.a. auch der Schaffung und Erhaltung von Rangstrukturen dient. Die Rangordnung begrenzt die Häufigkeit sowie Dauer und Intensität des Kampfverhaltens und erspart damit allen Mitgliedern einer Gruppe, Aufwand an Zeit und Energie sowie das Eingehen von Risiken.

Haltung, Selektion und Umgang mit Natursprungbullen
Provedor de dados: 21
Autores: Moosbauer, Stephanie; Postler, Günter; Schmidt, Eggert.
In der Milchrinderzucht erfolgt der gezielte Einsatz von Zuchttieren üblicherweise durch die künstliche Besamung. Der Einsatz von Deckbullen nimmt jedoch zu. Hierzu wurde eine Befragung von Landwirten, die einen Deckbullen halten, in Oberbayern durchgeführt. Obwohl es in der Praxis verschiedene Meinungen zu der Haltung und dem Umgang mit Natursprungbullen gibt, würden sich die befragten Betriebsleiter erneut dafür entscheiden.  Als Vorteil des Natursprungs wird von den untersuchten Betrieben vor allem die verbesserte Fruchtbarkeit der Kühe und der reduzierte Arbeitsaufwand gesehen. Demgegenüber sind als Nachteile das Risiko unerwünschter Zuchterfolge und der Platzbedarf für den Bullen zu sehen.   Die Zuchtbullen kommen überwiegend aus der eigenen Nachzucht...

Über die Zucht greift der Mensch am tiefsten und nachhaltigsten in die Entwicklung der Haustiere ein. Deshalb trägt er gerade auf diesem Gebiet eine besondere Verantwortung gegenüber den Haustieren, die er seinen Dienst und unter seine Obhut genommen hat. Die Nutztierzucht der letzten Jahrzehnte hat sich mit dem Ziel der kurzfristigen einzelbetrieblichen Gewinnmaximierung zunehmend von traditionellen Werten gelöst. Der Ökolandbau, dessen vorrangige Ziele der Schutz seiner Resourcen und die Nachhaltigkeit der Nahrungserzeugung sind, muss eigene adäquate Zuchtziele formulieren.

Provedor de dados: 21
Autores: Johanssen, Juni Rosann E.; Sørheim, Kristin; Brunberg, Emma; Strøm, Turid.
Denne rapporten omhandler den ene delen av et todelt prosjekt gjennomført av Norsk senter for økologisk landbruk. Formålet med denne delen av prosjektet var å finne ut om bruk av flis til dypstrø kan gi like god dyrevelferd som bruk av halm, og om det er forskjell på kostnader og arbeidsmengde. Det ble gjennomført et forsøk med to binger med ungdyr (kviger) på Tingvoll gard fra 11.1. til 4.4.2016, hvor dypstrø av flis og halm ble sammenlignet. Vi undersøkte dyras liggeatferd, renhet og forekomst av parasitter i dyras avføring. Strøet og dypstrøet ble undersøkt for innhold av mikroorganismer. Resultatene fra forsøket viste at dyra hadde signifikant lengre liggetid på halm enn flis. Det var ikke signifikant forskjell på antall liggeperioder eller tid per...

Autores: Frick, Rebekka; Weisshaidinger, Rainer; Moakes, Simon; Müller, Adrian; Bartel, Andreas; Schwank, Othmar; Petrasek, Richard; Biedermann, Roger; Stolze, Matthias.
Farming in the alpine countries of Austria and Switzerland fulfils important economic, socio-cultural and ecological functions for society. At the same time, it is responsible for important environmental impacts, whereas nitrogen balance surpluses and related impacts play a central role. It is crucial to reduce nitrogen inputs and site-adapted production and closing material cycles are core elements of ecologically sustainable land use.  The study analysed the effects of adapted beef and dairy systems on the environmental impact and the food production with the help of the SOL mass-flow model. This includes higher reliance on grassland-based feed by abandoning the use of concentrate feed and forage maize, locally adapted reduction of livestock numbers,...

Beef Cattle Farms’ Conversion to the Organic System. Recommendations for Success in the Face of Future Changes in a Global Context
Provedor de dados: 21
Autores: Escribano, A.J.
Abstract: Dehesa is a remarkable agroforestry system, which needs the implementation of sustainable production systems in order to reduce its deterioration. Moreover, its livestock farms need to adapt to a new global market context. As a response, the organic livestock sector has expanded not only globally but also in the region in search for increased overall sustainability. However, conversions to the organic system have been commonly carried out without analyzing farms’ feasibility to do so. This analysis is necessary before implementing any new production system in order to reduce both the diversity of externalities that the variety of contexts leads to and the vulnerability of the Dehesa ecosystem to small management changes. Within this context and...

Few years ago a farmer who usually sells his products in the organic bazaar of İstanbul, Feriköy had to face a business challenge; should he raise organic animals as well? When he shared his ideas with his regular customers they were interested and even excited with the idea. Government was providing financial support for this industry and for the customers, idea was interesting because they would have access to the dairy products which at that time were not easily found in the regular shops. The idea was good but it did not work; for some time customers (although very few) gave support; they provided partial resources for buying the animals, later for food but in the long run having fresh organic milk, cheese and yogurt turned out to be an expensive...

This research was conducted to study the direct fertilization combining 0 and 160 kg N ha-1 of cattle manure and green manure as branches of pigeon pea (Cajanus cajan L.) and their residual effects on two population densities of roquette (Eruca sativa Miller) crop, in Seropédica, Rio de Janeiro, Brazil. Yield, number of leaves plant-1, leaf area index, shoot fresh weight, stems dry matter, roots dry matter, leaves dry matter, total dry matter and plant height were measured. The experiment was a randomized block design set as a factorial 2 x 2 x 2, and three replications: 0 and 160 kg N ha-1 of cattle manure, 0 and 160 kg N ha-1 of branches of pigeon pea and 500,000 and 1,000,000 plants ha-1. The results indicate that the population density of 500,000...

Auswirkungen differenzierter ökologischer Bewirtschaftung von Ansaat- und Dauergrünland auf Futterangebot, Fressverhalten sowie Weideleistung und Schlachtreife von Ochsen und Färsen
Provedor de dados: 21
Autores: Swalve, Hermann H.; Schäfer, Stephan; Mitsch, Uta.
Von 2004 bis 2006 wurde durch die Universität Halle-Wittenberg am ZTT Iden der LLFG Sachsen-Anhalt ein Versuch zur Weidemast von Rindern auf 26 ha extensiv ökologisch bewirtschaftetem Dauergrünland in zwei Düngungsstufen (0 und 70 kg N/ha) durchgeführt. Die jährlich zwei Versuchsherden bestanden aus je circa 30 Absetzern (Ochsen und Färsen) üblicher Gebrauchskreuzungen (2004; tragende HF-Färsen). Der Tierbesatz lag bei max. 1 - 1,4 GV/ha. Die Versuchsflächen (vier Koppeln/Herde) lagen auf drei, bezüglich Bodenart, Feuchtigkeit und Pflanzenbestand, unterschiedlichen Standorten.  Die Artenzahl war vom vorhandenen Pflanzenbestand zu Versuchsbeginn abhängig. Ein Flächentyp (Ansaatgrünland, leichter Boden) zeigte sich äußerst problematisch hinsichtlich...

Long term performance of organic farming in the hills and uplands - Redesdale and Pwllpeiran organic units - OF0368
Provedor de dados: 21
Autores: Anon,.
During the 1990’s significant areas of hill and upland in the UK were converted to organic production. In the short term, this was driven by the downturn in conventional prices for beef and sheep, and the aid to conversion payments available. In more recent years there has been an expansion of organic farming in lowland beef and sheep, and arable systems. This provides a better opportunity to integrate hill and lowland production, and address some of the problems of infrastructure e.g. organic concentrate feed supply and limited finishing capacity for hill livestock. Decoupling of EU support from production, through the single farm payment scheme, will affect the financial performance and longer-term sustainability of both organic and conventional...

Quantifizierung der Methanemissionen bei Rindern mit Hilfe des fäkalen Biomarkers Archaeol
Provedor de dados: 21
Autores: Krattenmacher, Nina; Thaller, Georg.
Das im Verdauungstrakt von Wiederkauern produzierte Methan ist als Endprodukt anaerober Nahrungsumsetzung vom Tier nicht weiter verwertbar. Daher wird es ausgestoßen und stellt eine globale Belastung für das Klima dar. Aus diesen Gründen werden Versuche zur Senkung der Methanemission von Wiederkäuern mit unterschiedlichen Ansätzen verfolgt.  Ziel des Projektes MethanA war die Untersuchung eines im Kot detektierbaren Markers für die Methanemission und im Rahmen dessen die Evaluierung und Bewertung von Archaeol als Hilfsmerkmal für die Zucht auf verminderte Methanproduktion beim Rind.  In eigener Vorarbeit wurden bei zehn Kühen Gaswechselmessungen in Respirationskammern mittels zweier Durchgänge und Fütterung zweier verschiedener Rationen durchgeführt. Es...

Non-nutritive sucking such as cross-sucking, inter-sucking and sucking and licking parts of the pen is an oral abnormal behaviour shown by calves. This study examines factors affecting non-nutritive sucking behaviour in organic group-housed Austrian Fleckvieh calves (n=37 farms), focusing on non-weaned calves under 8 weeks of age. Factors associated with sucking on housing equipment and inter/cross-sucking were at least partly different thus pointing at different underlying motivations.

Utveckling av ett multivalent vaccin mot lungmask, studier av parasitens genetiska struktur och antigen variation
Provedor de dados: 21
Det finns cirka 1.7 millioner nötkreatur i Sverige. De producerar jordbruksprodukter till ett värde av 15 biljoner kronor årligen. Nötkreatur är dessutom betesdjur och bidrar till att vidmakthålla det öppna jordbrukslandskapet. Parasitinfektioner är otvetydigt ett av de största djurhälsoproblemen hos betesdjur. Angreppen måste följaktligen begränsas. Vaccination är att föredra vid kontroll av lungmasken Dictyocaulus viviparus. Det finns idag ett väl fungerande levande vaccin, men det har dessvärre även flera nackdelar. Avmaskning är således fortfarande hörnstenen i kontrollprogram mot lungmask. Användningen är dock ifrågasatt bland annat till följd av att vissa parasiter blivit resistenta. Det finns även ett utbrett motstånd mot läkemedelsrester i...

Handel und Gesundheit von «überzähligen» Kälbern im Berggebiet: eine Studie aus Graubünden
Provedor de dados: 21
Autores: Janett, Rut; Oehen, Bernadette.
Es fehlen Informationen zum Umgang mit Kälbern im Berggebiet. In dieser landwirtschaftlichen Nutzungszone ist die Tierhaltung wichtig und geprägt von der Alpwirtschaft. Im Rahmen dieser Arbeit wurden elf Leiter von Milch- und Mastbetrieben im Kanton Graubünden zur Kälbergesundheit befragt. Ihre Antworten wurden mit Ajzens «Theory of Planned Behavior» (TPB) analysiert. Die Befragten handeln Kälber vorwiegend regional. Aufgrund der Sömmerung ist der Kälberhandel saisonal. Manche beschreiben eine enge Kooperation zwischen den Milch- und den Mastbetrieben. Dies ist mit einem sorgfältigen Umgang mit den Tränkekälbern verbunden, was die Tiergesundheit unterstützt und den Einsatz von Antibiotika auf Einzeltiere beschränkt. Verbesserungspotenzial gibt es bei...

Oekobilanz-Vergleich von intensivem und extensivem Rindfleischproduktionsverfahren: Fallstudie anhand zweier Fallbeispiele
Provedor de dados: 21
Autores: Chassot, Dr. André; Philipp, Anita; Gaillard, Dr. Gérard.
The environmental impact of two contrasting beef production systems was determined by life cycle assessment (LCA). An extensive fattening system of Limousine x Simmental crossbred steers based on grass (EXT) was compared to an intensive fattening system of Simmental bulls (INT). The environmental impacts of EXT were similar or lower than those of INT. The largest differences were found in toxic effects on aquatic and terrestrial ecosystems. The amount and type of fertilizers used to produce the feed were the main source of difference between the systems. For all other environmental impacts however, there were no marked differences. It is concluded that the extensive use of grasslands for beef production has the potential to reduce the environmental impacts...

Der Einfluss veränderter genetischer Korrelationen auf den  Selektionserfolg bei Selektion mit einem Ökologischen  Gesamtzuchtwert
Provedor de dados: 21
Autores: Krogmeier, Dieter; Herold, Pera; Postler, Günter; Steinwidder, Andreas.
Genetic correlations between milk yield and different fitness traits were estimated in Fleckvieh and Brown Swiss cattle. These updated correlations were taken into  account in the calculation of an organic total merit index (ÖZW), where the fitness traits have larger weight than in the conventional total merit index (GZW). As a  consequence, the relative theoretical selection response in functional traits (18-23%) was higher and the selection response in milk yield was lower than before. This index  is therefore more suited for the ecological breeders but may also implicate that biological and conventional breeding goals will drift apart. To ensure that in the long term suitable bulls for biological farms will be available, AI  stations will have to...

Vor dem Hintergrund, daß im biologisch-dynamischen Landbau dem Rind als Haustier eine besondere Wertschätzung zukommt, beschäftigt sich diese Diplomarbeit mit den verschiedenen Gesichtspunkten, unter denen das Rind in der Biologisch-Dynamischen Wirtschaftsweise und in der anthroposophischen Literatur beschrieben wird.    Bei den verschiedenen Themen, unter denen das Rind „behandelt“ wird, hat man es oftmals mit Erfahrungen zu tun, die über die gewöhnlichen naturwissenschaftlichen Gesichtspunkte hinausgehen. Will man sie verstehen und in ihrem Wert beurteilen, muß man sich zuerst mit den Erkenntnismethoden, mit denen diese Anschauungen gewonnen wurden, auseinandersetzen. Sowohl die von Goethe entwickelte Methode des Studiums der organischen Natur, als auch...

Eight years of organic farming at Pwllpeiran – livestock production and the financial performance of organic upland
Provedor de dados: 21
Autores: Frost, David; McLean, Barbara M L; Evans, D Eifion.
This report was presented at the UK Organic Research 2002 Conference. Established for 8 years, this project evaluates the practicalities of organic beef and sheep production on an upland farm in an ESA. Grassland productivity, stocking rates and animal performance are closely related to seasonal variations in the clover content of the small area of improved land. Improving sales have been offset by increasing input costs. Subsidy payments assist financial performance, but ESA prescriptions effectively prevent increased production.

The role of subsidies in beef cattle farms in SW Spain: a comparison of organic and extensive farms
Provedor de dados: 21
Autores: Escribano, A.J.; Gaspar, P.; Pulido, A.F.; Mesias, F.J.; Escribano, M.; Pulido, F.; Rodriguez De Ledesma, A.
Livestock farming systems of the Spanish rangelands (dehesas) are traditional systems characteristic of the Iberian Peninsula where native herbaceous vegetation and evergreen species of Quercus provide the foundation for extensive beef farming enterprises. Dehesas are considered to be the most extensive, diverse, and low-intensity land use systems in Europe. Nevertheless, in the last twenty years, the Common Agricultural Policy (CAP) has produced some important effects in these systems, specially an increase of the stocking rate. Although CAP policies contributed to stabilizing income in dehesa farms, they also produced loss of sustainability. Nevertheless, EU subsidies have become a key element in these enterprises, accounting for as much as 30% of the...

Autores: Bapst, B.; Bieber, A.; Haas, E.
A survey on 1000 organic dairy cattle farms was done to obtain information on the state of breeding affairs in Switzerland. The response of 60% of returned questionnaires was very high. Milk performance data were average for organic as well as for traditionally managed farms. The farmers weighted functional traits to be very important in breeding.  The bulls used on organic farms were compared with the bulls used on traditional farms. A total of 25067 organic and 28003 traditional matings of Swiss Braunvieh was analysed. The comparison of breeding values of the sires showed that in the scope of selection strategies the functional traits were not as important. It is concluded that organic farmers persecute an organic breeding strategy but in the particular...

„Das, was heute für uns normal ist, dass wir uns treffen und austauschen – das gab es früher nicht!“  Das Netzwerk Ökologische Tierzucht bringt seit 2002 die Pioniere und Experten zusammen, die sich in der Ökologischen Tierzucht engagieren. Das Netzwerk (2. Projektphase 2005-2007) arbeitet in Form von tierartbezogenen Arbeitsgruppen, die ihre Ergebnisse in Workshops diskutieren. Geleitet wurden die Fachgruppen von ausgewiesenen Experten; die Koordination übernahm die Zukunftsstiftung Landwirtschaft.   Tierzucht ist als Thema auf den Betrieben und bei den Beratern oftmals weit weg. Das Potenzial, das eine artgemäße Tierzucht gerade auch für die Tiergesundheit und damit auch für die ökonomische Situation bietet, wird nicht gesehen. Das Netzwerk kann hier...

Studien zu Genotyp-Umwelt-Interaktionen beim Deutschen  Schwarzbunten Niederungsrind
Provedor de dados: 21
Autores: Jaeger, Maria; Brügemann, Kerstin; König, S.
The aims of the present study were i) to analyse the genetic structure of the local black and white cattle breed (DSN), and ii) to analyse genotype by environment interactions based on defined herd parameter groups (geographic, environmental, phenotypic descriptors). The study considered 3688 DSN and 3599 HF cows from 46 herds keeping both breeds. Farms mostly reflected pasture based low input production systems. A multiple trait approach, i.e. defining same traits in different clusters as two different traits, was applied to prove genotype by environment interactions based on genetic correlation estimates. Genetic correlations between low heritability functional traits were lower than for production traits. Especially for functional traits such as somatic...

Autores: Kerp, M.; Herold, Pera.
Different traits have been defined to describe the performance of dairy animals during their lifetime: productive lifetime, lifetime production, life efficiency and contribution trouble-free cows that reach the performance optimum of lactations. This continuous performance should be on basis of good roughage feed efficiency. Within the present total merit indices it is not possible to determine which cow fulfils these demands on longevity, health, performance and cost reduction. Further research is necessary to investigate the suitability of this trait for breeding value estimation or if the calculation of an index may be more useful.

Spisekvalitet af økologisk kød fra unge krydsningsdyr
Provedor de dados: 21
Autores: Therkildsen, M.; Vestergaard, M.
Produktionen af økologisk kød fra ungdyr er ikke særligt udbredt i Danmark til trods for et veletableret økologisk mælkeproduktionssystem, som egentlig godt kunne levere tyrekalvene til den økologiske kødproduktion. I stedet bliver disse kalve solgt til konventionelle kødproducenter på grund af lave udbytteresultater i de økologiske produktionssystemer.  Formålet med dette projekt var at afprøve et koncept til production af økologisk kød fra ungkvæg baseret på krydsningsdyr fra malkekøer kødkvægstyre. Resultaterne viser, at kvie- og ungtyrekrydsninger af Limousine x Holstein kan være et alternativ til renracede Holstein ungtyre i økologisk oksekødsproduktion grundet den øgede tilvækst og form-klassificering, aroma og smag hos krydsningsdyrene.

Feeding mastitis milk to organic dairy calves: effect on health and performance during suckling and on udder health at first calving
Provedor de dados: 21
Autores: Abb-Schwedler, Katharina; Maeschli, Ariane; Boss, Renate; Graber, Hans U.; Steiner, Adrian; Klocke, Peter.
Background  Infection pathways of S. aureus udder infections in heifers are still not well understood. One hypothesis is that calves become infected with S. aureus via feeding mastitis milk. Especially on small-scale farms, pasteurisers are not economic. The purpose of this randomised comparative study was to investigate the influence of feeding milk containing S. aureus genotype B (SAGTB) on the health and development of calves and udder health of the respective heifers. Additionally, a method reducing the bacterial load to obtain safer feeding milk was tested. Thirty-four calves were fed mastitis milk from cows with subclinical SAGTB mastitis. One group was fed untreated milk (UMG). For the other group, milk was thermised at 61°C for one minute (heat...

Warum Streicheln wichtig ist
Provedor de dados: 21
Autores: Probst, Johanna K.
Mutterkuhhaltung wird mit tiergerechter Haltung in Verbindung gebracht aber auch vermehrt mit aggressiven Tieren. Nervöses Verhalten und Stressreaktionen der Tiere entstehen meistens aus Furcht vor dem Menschen. Dies beruht auf der Tatsache, dass der direkte Kontakt zwischen Mensch und Tier, wie er in der Milchviehhaltung automatisch entsteht, bei der Mutterkuhhaltung wegfällt. Hier treffen Mensch und Tier seltener direkt aufeinander, dann wenn notwenige Maßnahmen durchgeführt werden müssen. Z.B. das Einziehen der Ohrmarken, das Kastrieren männlicher Kälber, Impfungen und die medikamentöse Versorgung erkrankter Tiere. Für die Tiere sind diese Eingriffe unangenehm und meist mit Stress und Schmerzen verbunden – und bleiben bei den Tieren negativ im...

Autores: Walkenhorst, Michael; Heil, Fritz; Ivemeyer, Silvia; Klocke, Peter; Notz, Christophe; Spranger, Jörg.
Data of mastitis causing factors will be collected on 100 new farms per year in Switzerland: housing, feeding, human-animal-interaction, milking technology, milking hygiene. These data will be connected to the mastitis status of the herd based on quarter milk samples and milk recording data. During a period of at least 2 years these farms will be intensively advised by the project team and their practical veterinarians. Therapies will primarily be based on homeopathic remedies. The development of mastitis causing factors and the mastitis status of the farms is followed up at regular intervals to show possible correlations between (changing) factors and mastitis status. In addition, a network of health data should be implemented for providing information...

Relationship between stress-related exsanguination blood variables, vocalisation, and stressors imposed on cattle between lairage and stunning box under conventional abattoir conditions
Provedor de dados: 21
Autores: Probst, J.K.; Spengler Neff, A.; Hillmann, E.; Kreuzer, M.; Koch-Mathis, M.; Leiber, F.
Physiological and behavioural reactions of cattle to handling procedures in a commercial abattoir (electrical prodding actions and duration of the animals׳ stay in the stunning box) were evaluated and set in relation to sex, breed type, and carcass weight. A total of 192 cattle comprised of 45 bulls, 61 steers, and 86 heifers from different breed types (30 dairy breed, 70 beef breed, and 92 crossbreds) were observed from lairage to slaughter during one day. The frequency of electrical proddings and the waiting time in the stunning box was recorded for each individual. As a measure of a behavioural stress response, the number of vocalising animals was recorded. Exsanguination blood serum samples were analysed for cortisol, glucose, and lactate...

Strategien der Parasitenbekämpfung beim Milchvieh in Weideproduktionssystemen: Was kann die Zucht leisten?
Provedor de dados: 21
Autores: May, Katharina; Brügemann, Kerstin; Strube, Christina; König, Sven.
Weidebasierte Produktionssysteme haben in den letzten Jahren wieder einen Aufschwung in Deutschland erfahren. Diese Tendenz wird durch die in den öffentlichen und politischen Fokus gerückte Debatte um Tierwohl und Gesundheit in der Nutztierhaltung verstärkt. Immer mehr gewinnen dabei nicht nur Tierwohl-Indikatoren an Bedeutung, welche einen Rückschluss auf die Haltungsbedingungen erlauben, sondern auch Maßnahmen zur Reduktion und Prophylaxe krankheitsverursachender Erreger wird vermehrt Berücksichtigung geschenkt. Insbesondere Infektionen mit Endoparasiten wie Magen-Darm-Strongyliden (MDS), dem Rinderlungenwurm (Dictyocaulus viviparus), aber vor allem solche mit dem großen Leberegel (Fasciola hepatica), stellen bei Milchvieh in Weidehaltung ein...

Provedor de dados: 21
Autores: Gillandt, Kathia; Kemper, Nicole.
Über einen Zeitraum von 18 Monaten wurden Gesundheitsdaten von fünf Angusrind- Mutterkuh-Herden an vier Standorten in Deutschland erhoben. Ein Projektschwerpunkt lag in der parasitologischen Untersuchung der Herden, wobei in weniger als der Hälfte (41%) der untersuchten Proben Parasitenstadien nachgewiesen wurden. Magen-Darm Strongyliden und Kokzidien stellten dabei regionsübergreifend wesentliche Befunde dar, wohingegen Leberegel, Lungen- und Bandwürmer je nach Standort variierten. Andere Arten wurden vereinzelt nachgewiesen. Die in diesem Zusammenhang ausgewerteten Betriebsfragebögen wiesen auf eine geringe Sensibilisierung der Landwirte für die Parasiten-Problematik hin.

Beitebruk og dyrehold er i stadig forandring, og dyretall og dyreslag endres. I et sambeite – hvor flere har beiterettigheter – kan en vurdering av beitekapasitet gi et bedre grunnlag for å planlegge beitesesongen, vurdere antall dyr som skal slippes i området og vurdere behovet for evt. tilleggsfôring. Dette var bakgrunnen for at NORSØK ble bedt om å vurdere beitekapasiteten i Grøvdalen sambeite øverst i Isfjorden i Rauma kommune. Beitekapasiteten sier noe om hvor mange dyr som bør beite innenfor et gitt område. Det er mange faktorer som spiller inn på husdyra sin beitebruk, og det er lite forskning gjort på området. Det er derfor viktig å understreke at det er stor usikkerhet knyttet til vurdering av beitekapasitet, og ingen eksakte svar kan gis. Det er...

Jeder Landwirt fasst seine Kühe an ihren Hörnern, um herauszufinden ob das Tier gesund ist: dann haben sie warme Hörner. Hörner sind Organe des Rindes, die das Einzeltier physiologisch in der Auseinandersetzung mit der Umgebung unterstützen, nachweislich bei der Regulierung der Körpertemperatur. Behornte Tiere können vermutlich besser mit Temperaturschwankungen und Hitzestress umgehen. Dies ist vor allem bei Weidegang von Bedeutung.

Denne rapporten omhandler den ene delen av et todelt prosjekt gjennomført av Norsk senter for økologisk landbruk. Formålet med denne delen av prosjektet var å finne ut om bruk av flis til dypstrø kan gi like god dyrevelferd som bruk av halm, og om det er forskjell på kostnader og arbeidsmengde. Det ble gjennomført et forsøk med to binger med ungdyr (kviger) på Tingvoll gard fra 11.1. til 4.4.2016, hvor dypstrø av flis og halm ble sammenlignet. Vi undersøkte dyras liggeatferd, renhet og forekomst av parasitter i dyras avføring. Strøet og dypstrøet ble undersøkt for innhold av mikroorganismer. Resultatene fra forsøket viste at dyra hadde signifikant lengre liggetid på halm enn flis. Det var ikke signifikant forskjell på antall liggeperioder eller tid per...

Erfolgreiches Rinderhandling: wahrnehmen, verstehen, kommunizieren
Provedor de dados: 21
Autores: Probst, Johanna K.; Spengler, Anet.
Die Mutterkuhhaltung und andere extensive Haltungsformen zur Rindfleischproduktion auf der Weide gelten als besonders tierfreundlich. Durch den geringen Kontakt mit Menschen werden die Tiere jedoch oftmals menschenscheu. Dies Erschwert den Umgang mit ihnen in Situationen, in denen der Kontakt unumgänglich ist, und führt zu Stress bei Rindern und Menschen. Ein gutes Verständnis des Verhaltens der Rinder und die Befolgung einiger Grundregeln im Kontakt mit ihnen können den Umgang wesentlich erleichtern und entspannen. Diese Merkblatt vermittelt die Grundlagen zur Wahrnehmung und zum Lernverhalten der Hausrinder und zeigt au, wie Tierhalterinnen und Tierhalter eine positive Beziehung zu ihren Rindern gestalten können.

Development of Cattle Housing for Sheepdrove Organic Farm
Provedor de dados: 21
Autores: Philipps, Lois; Clark, Fergus.
Housing criteria should be based around the fundamental concept that “the housing should be adapted to meet the needs of the animal and NOT the adaptation of the animal to meet the needs of the building”.  In practice this means housing conditions that meet the needs of the animals in terms of their social behaviour, eg subdominant animals must have the opportunity to withdraw or avoid higher status animals. This may mean greater space at feeding and watering sites greater space per cow alley widths sufficiently wide to allow free passage and the avoidance of dead ends. Good husbandry skills and herd stability are also important. (3rd NAHWOA Workshop 2002)  In order to achieve these criteria there are two areas under consideration, improvements to the...

Untersuchungen zur Eignung von Fleckviehbullen mit unterschiedlichem genetischen Milchleistungspotential für ökologisch wirtschaftende Milchviehbetriebe
Provedor de dados: 21
Autores: Gerber, Antonia; Krogmeier, Dieter.
The present study examines milk yield traits and functional traits of Simmental dairy cows in organized biological dairy herds in Bavaria. Data from 3588 daughters of 239 bulls born from 1993-1994 were classified by relative breeding values for milk yield (MW) of sire (groups with low, average and high genetic potential for milk yield).   Milk, fat and protein yield in first and second lactation increased by 9-13% from low to high genetic merit group. No significant negative effects on fertility, calving ease and somatic cell count with increasing milk yield were observed.  Genetic correlations between milk yield traits on organic and conventional farms were about or above rg = 0,90, not indicating any serious genotype by environment interac-tion....

Do organic livestock farms differ from low-input conventional ones? Insights based on beef cattle in southern Europe
Provedor de dados: 21
Autores: Escribano, A.J.
The objective of this study is to determine whether there are clear differences between conventional (but low-input) and organic beef cattle farms located in the Southwest of Spain. 33 conventional and 30 organic farms were compared in terms of structure, technical management, and performance. The results showed that organic farms (‘All Organic’) mainly focus on the production of calves at weaning age which are fattened in conventional holdings (‘Organic 1’; n= 22). The remaining organic farms (‘Organic 2’; n=11) showed to participate in almost all stages of the agri-value chain. ‘Conventional’ farms were mainly dedicated to producing calves at weaning age (similarly to Organic 1).  Organic 1 had the smallest herd size: 80.18 LU, p&lt;0.05). Organic 2...

Provedor de dados: 21
Autores: Probst, Johanna K.; Hillmann, Edna; Leiber, Florian; Kreuzer, Michael; Spengler Neff, Anet.
In der Studie wurde untersucht, wie sich eine Handling Methode (basierend auf TTouch®) auf extensiv gehaltene Limousin Kreuzungstiere (15 Monate alt) auswirkt. Vor Beginn des Handlings wurde der erste Ausweichdistanztest (AWD-Test) durchgeführt. Anhand dieser Ergebnisse wurden zwei Gruppen mit jeweils ähnlichen Ausweichdistanzen gebildet: eine Handlinggruppe (HG = 1♀, 4♂) und eine Kontrollgruppe (KG =2♀, 3♂). Das “head-neck-region Handling” wurde 10-mal für je 8 min innerhalb von 5 Wochen vor der Schlachtung durchgeführt und beinhaltete die Anwendung der TTouch® Methode an der Kopf-Hals Region der Tiere. Ein zweiter AWD-Test wurde nach allen Handlingsessions, kurz vor dem Schlachttermin durchgeführt. Blutserumproben wurden während des Entblutens am...

Erhebliche Effizienzpotenziale in der Färsenaufzucht der ökologischen Milchproduktion
Provedor de dados: 21
Autores: Kiefer, Lukas; Menzel, Friederike; Over, Ralf; Bahrs, Enno.
In many organic farms there is a huge potential to increase efficiency in rearing heifers for replacement. This is the result of a study in 36 organic dairy farms with pasture from South Germany, which were analyzed economically in the years 2009 – 2011. In particular farms with high production efficiency and low production costs per heifer show decreased production times per cow for some months, but this effect is overcompensated by higher milk yields per cow. This is one reason why they perform economically better with regard to the dairy farm. The most important factors influencing the production costs per heifer are the costs for forage and labor. Based on the results of this study, more efficient rearing of heifers with lower production costs seems...

Growth and carcass quality of suckler calves grazing at the farm or in the mountain
Provedor de dados: 21
Autores: Steinshamn, Håvard; Höglind, Mats; Havrevoll, Øystein; Saarem, Kristin; Lombnæs, Inger Helene; Svendsen, Asgeir.
The objective was to examine the effect of mountain grazing on the growth and meat quality of suckler calves. Suckler calves with their dams were raised on either cultivated pasture (C) or free range on mountain/forest pasture (M) on four and five commercial farms in 2006 and 2007, respectively. The M included different vegetation types from open, grass-dominated meadows to forests with patches of grasses, herbs and shrubs among the trees. All calves were slaughtered at the end of the grazing season at an average age of 203 (2006) and 193 days (2007). On average, there was no effect of pasture type on production traits except for carcass fatness that was higher on M than on C. In 2006, significantly higher live weight gain and carcass weight were found in...

Jeder Betrieb muss sein eigenes Zuchtziel haben
Provedor de dados: 21
Autores: Bapst, Beat.
Züchten ist mehr als nur eine gute Stierenwahl treffen. Ebenso wichtig ist es, die Möglichkeiten und Grenzen des Betriebes realistisch einzuschätzen. Besonders in der Rindviehzucht können auf dem einzelnen Biobetrieb ansehnliche Erfolge verbucht werden, auch wenn es im Moment noch kein speziell auf den Biolandbau zugeschnittenes Zuchtprogramm gibt.     Beat Bapst von der FiBL-Fachgruppe Tierhaltung und Tierzucht setzt sich intensiv mit der Entwicklung einer Rindviehzucht für den biologischen Landbau auseinander. Leistungen spielen dabei zwar auch eine Rolle, aber nielosgelöst, sondern eingebettet ist die Verhältnisse des Betriebs.

Lungmask hos nötkreatur inom ekologisk produktion
Provedor de dados: 21
Det finns indikationer om att lungmaskinfektion hos nötkreatur fått ökat genomslag i landet under senare år. Vissa aspekter rörande parasiten smittvägar är dock oklara under svenska drifts- och klimatförhållanden. Syftet med projektet är att klargöra faktorer som påverkar spridning och förekomst av lungmaskinfektioner i svenska nötkreatursbesättningar. Vår forskning har visat att vilda idisslare inte är smittreservoarer för nötkreaturens lungmaskart, vilket står i motsats till den tidigare uppfattningen. Kännedom om de frilevande larverna förmåga att övervintra på betesmarkerna är däremot fortfarande bristfällig. Lokala anpassningar avseende resistens mot yttre faktorer och hur denna motståndskraften påverkas av genflödet mellan parasitpopulationer skall...

Low stress and safe handling of outdoor cattle - effective measures to improve work environment and avoid dangerous situations
Provedor de dados: 21
Autores: Geng, Q.; Atkinson, S.; Salomon, E.
Grazing cattle are needed to preserve 450 000 hectares of semi-natural grasslands of high biodiversity in Sweden. Keeping cattle outdoors promotes their health and possibili¬ties to conduct natural behaviors. Working with cattle on pasture however, can increase accident rates (Health and Safety Authority, 2011). During the last two years, five fatali¬ties and several accidents have occurred during handling of cattle in Sweden. A method, based on knowledge of the animals’ natural behavior, referred to as low stress stock han¬dling (LSS-method), has been introduced to Sweden for cattle handling (Atkinson, 2011). A handler who consistently uses this method prevents the use of hits, sticks, harsh voice or negative forceful handling techniques. A consistent...

Full fart på fellesbeite i førti år
Provedor de dados: 21
Autores: Bergslid, Ildri (Rose) Kristine.
Storslettet fellesbeite er delt inn i 18 ulike skifter som kyrne beiter i tur og orden gjennom sommeren. Skiftene varierer i størrelse fra 8 – 30 daa. Kyrne er ute døgnet rundt. Sesongen avsluttes rundt 10. september. Det settes opp turnus for hele sesongen, og det er alltid to som melker; en fast ansatt i tillegg til en av gårdbrukerne. En uke melking og to uker melkefri gjennom sommeren gir fleksibilitet til anna arbeid, ferie og fritid gjennom sommeren.

Organic farming in the uplands – appraisal of a development programme
Provedor de dados: 21
Autores: Frost, David.
There is a widespread assumption that conversion of livestock production systems in the uplands can be achieved with minimal change to existing hill farming practices and yet still deliver environmental and financial benefits. This assumption needs to be examined because conversion of upland farm enterprises poses particular issues for organic farming, Frost (1999). The certifying bodies acknowledge that some of these issues are not adequately covered by the current standards for organic agriculture. The development of a hill farming organic system at Pwllpeiran was established to provide evidence for such an appraisal, Powell (1999).    Appraisal of the project indicates that organic beef and sheep production can be a viable option in the uplands. Long...

Productive, environmental and economic performances assessments of organic and conventional suckler cattle farming systems
Provedor de dados: 21
Autores: Veysset, Patrick; Lherm, Michel; Bébin, Didier.
Conversion to OF was simulated for four specialized suckler-beef systems by coupling an economic optimization model (“Opt’INRA”) with a model assessing non-renewable energy (NRE) consumption and greenhouse gas (GHG) emissions (“PLANETE”). After adaptation of the production system, and based on average prices over 2004–2008, we analyzed the productive, environmental and economic impacts of the conversion process. The ban on chemical fertilizers led to a drop in farm area productivity. For these specialized farms, meat production decreased by 18% to 37% depending on initial level of intensification. The reduced use of inputs results in a 23% to 45% drop in NRE consumption/ha, 5–20% of which is a drop in NRE per ton of live weight produced. Its methane...

Der Ökologische Gesamtzuchtwert für Fleckvieh, Braunvieh und Gelbvieh
Provedor de dados: 21
Autores: Krogmeier, D.
Der ökologische Gesamtzuchtwert (ÖZW) ist ein Gesamtzuchtwert, der der Zuchtzielsetzung in der ökologischen Milchviehhaltung entspricht. Der ÖZW stellt eine „ökologische Reihung“ der aktuellen Besamungsbullen dar und ist ein wichtiges Hilfsmittel für die Zuchtarbeit im ökologisch arbeitenden Milchviehbetrieb.   In den Ausführungen wird der ÖZW in seinen Einzelheiten beschrieben und aufgezeigt, dass ein ökologischer Zuchtwert nicht mit einem ökologisch orientierten Zuchtprogramm gleichzusetzen ist. Ein solches Programm ist aufgrund der geringen Anzahl von Herdbuchkühen in ökologischen Betrieben nicht durchführbar. Eine Beteiligung am bestehenden Zuchtprogramm ist bereits über Paarungsempfehlungen realisiert und sollte weiterentwickelt werden.   Wenn es...

Organic Beef Production with Emphasis on Welfare, Health and Product Quality
Provedor de dados: 21
Autores: Nielsen, Ph.D. student Bea Klinzing.
Organic beef production in Europe is based on grazing in the summertime and feeding of minimum 60% of roughage during whole the year. Although these recommendations should improve health and welfare several aspects can give problems in organic beef production systems. This paper gives an overview of welfare, health and product quality in organic beef production with emphasis on organic steer production based on dairy breed bull calves. A short overview of different production systems is given with emphasis on the effect on health, and welfare. Feeding aspects are discussed and farm studies have shown that organic steer production is based on high amounts of roughages, and only small amounts of cereals are used compared to a conventional production of bulls...

Gülle besser verstehen – Ergebnisse des Gülleuntersuchungsprojektes 2017
Provedor de dados: 21
Autores: Angeringer, Wolfgang; Weber, Christina; Freudenberger, Gertrude.
Flüssige Wirtschaftsdünger, also alle Formen von Gülle und Jauche, geraten heute gesellschaftlich immer mehr in Kritik. Aus landwirtschaftlicher Sicht steht die verlustarme Ausbringung, vor allem in Hinblick auf gasförmige Stickstoffverluste im Vordergrund. Die Bevölkerung nimmt diese Ausgasungen, vor allem Ammoniak und Schwefelverbindungen als Geruchsbelästigung wahr, wodurch es immer häuﬁ ger zu Auseinandersetzungen kommt. Entsprechend groß war das Interesse der Landwirte, am Gülleprojekt der LK Steiermark teilzunehmen. Die Untersuchung beinhaltete Nährstoffgehalte, Trockenmasse und pH-Wert im NIRS-Schnelltestverfahren. Ziel war es, aus der Fülle an Proben zusammen mit Hintergrundinformationen über die Güllebehandlungen und Systeme auf den Betrieben,...

Storfe, klima og bærekraft – en litteraturstudie
Provedor de dados: 21
Autores: Bergslid, Ildrid Kristine.
I følge FAO (2013) vil verdens befolkning øke fra dagens 7,2 milliarder til 9,6 milliarder i 2050. Samtidig må miljø- og klimabelastningene av matproduksjonen reduseres. Dette vil øke presset på jordbruket verden over.  Jordbruksdrift og husdyrhold belaster miljø og klima i ulik grad, og det er stort nasjonalt og internasjonalt fokus på ulike husdyrproduksjoner og driftssystemers effekter på miljø og klima. Formålet med denne rapporten er å se nærmere på produksjon av storfekjøtt, og om ulike driftssystem (intensiv vs. ekstensiv) belaster miljø og klima i ulik grad. Rapporten baserer seg på nasjonale og internasjonale forskningsresultater og rapporter.  Storfe i intensive driftssystemer har en høy kraftfôrandel i fôrrasjonen. Det betyr at de legger beslag...

Stature is affected by many polymorphisms of small effect in humans1. In contrast, variation in dogs, even within breeds, has been suggested to be largely due to variants in a small number of genes2,3. Here we use data from cattle to compare the genetic architecture of stature to those in humans and dogs. We conducted a meta-analysis for stature using 58,265 cattle from 17 populations with 25.4 million imputed whole-genome sequence variants. Results showed that the genetic architecture of stature in cattle is similar to that in humans, as the lead variants in 163 significantly associated genomic regions (P &lt; 5 × 10−8) explained at most 13.8% of the phenotypic variance. Most of these variants were noncoding, including variants that were also expression...

Autores: Aanensen, Lise; Henriksen, Britt I. F.
På oppdrag fra Relelverksutvalget for økologisk produksjon (RVU) har Bioforsk utført en vurdering av fordeler og ulemper knyttet til luftekravet for okser i økologisk produksjon, samt en utredning av mulige løsninger for lufting av okser. I tillegg er det utført en vudering av alternative metoder for produksjon av økologisk storfekjøtt, for eksempel produksjon av kastrat-, kvige- og kalvekjøtt. Økologisk produksjon av storfekjøtt er vurdert med bakgrunn i kravet om lufting av okser. Regelverket for økologisk produksjon(EU-reg. 2091/92) sier at "(...) okser skal ha tilgang til beiter eller luftegårder. Okser over ett år gamle kan holdes i et husdyrrom med fri adgang til en luftegård hele året, i stedet for å gå på beite i sommerperioden." Nytt regelverk som...

Can early handling of suckler beef calves reduce their timidity towards humans?
Provedor de dados: 21
Autores: Probst, Johanna K.; Hillmann, Edna; Leiber, Florian; Kreuzer, Michael; Spengler Neff, Anet.
In herds of suckler beef cows the relationship between humans and animals is an important issue concerning animal handling.  Unlike dairy cow herds, suckler beef herds are less used to close contact with humans. Due to low management input animals  may be difficult to handle during treatments like medical care, routine handling or at slaughter house.

The objective of this work was to assess the degree of multicollinearity and to identify the variables involved in linear dependence relations in additive-dominant models. Data of birth weight (n=141,567), yearling weight (n=58,124), and scrotal circumference (n=20,371) of Montana Tropical composite cattle were used. Diagnosis of multicollinearity was based on the variance inflation factor (VIF) and on the evaluation of the condition indexes and eigenvalues from the correlation matrix among explanatory variables. The first model studied (RM) included the fixed effect of dam age class at calving and the covariates associated to the direct and maternal additive and non-additive effects. The second model (R) included all the effects of the RM model except the...

Abstract: The objective of this work was to evaluate the performance of crossbred steers post-weaned in an integrated crop-livestock system (ICL) and finished in a feedlot, fed either a high-level concentrate diet or whole corn with no roughage. Weaned calves of two breed groups - ½ Angus × ½ Nellore, and ½ Charolais × ¼ Angus × ¼ Nellore - were allotted in a completely randomized experimental design (CRD). During the rainy season, the ½ Angus × ½ Nellore animals showed a higher performance than the ½ Charolais × ¼ Angus ×¼ Nellore ones, with 0.748 and 0.490 kg average daily gain, respectively. The productivity in the post-weaning period was 926 kg ha-1 body weight in a 11-month period, in the ICL system. Subsequently, the animals were confined and fed...

Autores: Carvalho,Caio Victor Damasceno; Bittencourt,Thereza Cristina Calmon de.
Abstract:The objective of this work was to define the traits that should be included as breeding objectives for Nellore cattle, according to simulations with a bio-economic model for rearing systems. The economic values (EVs) of the traits were calculated as the differences between the profits due to an increased performance of 1% in each trait, with the others traits remaining constant. To determine the impact of each selection on the revenue system, two scenarios were simulated based on the traits being selected. In the first scenario, the adopted selection criteria were: weaning weight (WW), weaning rate (WR), yearling weight (YW), and mature cow weight (MCW). In the second scenario, the cumulative productivity (CP) of dams was used as an indirect...

Abstract: The objective of this work was to evaluate the effects of genomic information on the genetic evaluation of hip height in Brahman cattle using different matrices built from genomic and pedigree data. Hip height measurements from 1,695 animals, genotyped with high-density SNP chip or imputed from 50 K high-density SNP chip, were used. The numerator relationship matrix (NRM) was compared with the H matrix, which incorporated the NRM and genomic relationship (G) matrix simultaneously. The genotypes were used to estimate three versions of G: observed allele frequency (HGOF), average minor allele frequency (HGMF), and frequency of 0.5 for all markers (HG50). For matrix comparisons, animal data were either used in full or divided into calibration (80%...

Abstract: The objective of this work was to evaluate the genetic diversity of Brahman cattle in Brazil with pedigree analysis. Genealogical records of a subpopulation were used considering all pedigree information (Pt) and the pedigree information divided into two periods (P1, from 1994 to 2004; and P2, from 2005 to 2012) or according to the raising system (Ppt, animals on pasture; or Pst, on stable). Estimates were obtained for average inbreeding coefficients, generation intervals (GI), number of equivalent known generation (CGE), number of founders (Nf), effective number of founders (fe), effective number of ancestors (fa), and founder genome equivalents (fg). The average inbreeding coefficients were 11.97, 7.79, 11.95, 11.74, and 11.31% for Pt, P1, P2,...

Mitochondrial DNA of Nellore and European x Nellore crossing cattle of high performance
Provedor de dados: 86
Autores: Curi,Rogério Abdallah; Mota,Lígia Souza Lima Silveira da; Silveira,Antônio Carlos.
The objective of this work was to evaluate, through a polymorphism in the ND5 gene of the bovine mitochondrial DNA, the frequency of Bos taurus indicus mtDNA individuals in a sample of Nellore purebred origin animals (n = 69) and crossbred animals originated from crosses of European sires and Nellore purebred origin females (n = 275). Only 2.26% (8/354) of the animals presented Bos taurus indicus mtDNA. The high frequency of Bos taurus taurus mtDNA in these animals can be a consequence of selection, once the animals studied are originated from selected lineages of high performance for meat production.

The ratios 1:10, 1:25, and 1:40 were used in native pastures with a mean stocking rate of 0.27 mature animal unit per hectare over two consecutive breeding seasons. Statistical analysis did not show any effect (P&gt;0.05) of year (P = 0.2097), animal category (P = 0.0773), bull:cow ratio (0.8134) on reproductive performance. However, the pregnancy rate in a multiple bull system was higher (P = 0.0228) than in the individual bull system. An evaluation of the economic impact of this management system in the extensive Lowland herds showed that at the ratio of 1:10 the bulls...

ABSTRACT: Pantanal plain has large extensions of land formed by many types of landscapes suitable to extensive livestock system. Open grasslands and lowlands are formed by forage such as grasses and forbs widely consumed by cattle. However, climatic and human factors can promote the dissemination of invasive shrub species such as canjiqueira (Byrsonima cydoniifolia A. Juss) making it necessary, in many cases, the human intervention to control the invasion. The present work had as objective to determine the economic threshold level to control canjiqueira through two methods: tractor driven blade and link chains pulled by tractor in different invasion levels plants per hectare. Economic Threshold proved to be a tool for efficient and effective management for...

The paper analyzed the impacts of the price of finishing steers on the price of backgrounding steers in the State of São Paulo from January 1995 to January 2007. The ADF Unit Root test, the Granger causality test, the Johansen’s co-integration test, and the method of Vector Auto-Regression (VAR) were used. In this period, the results indicated that exist a unidirectional relationship among the prices of finishing steers and backgrounding steers, confirming the importance of the prices of finishing steers on the prices formation of the backgrounding steers, but the prices had no equilibrium relationship in the long term.

An Exploratory Assessment of the Economic Impact of Forage Options for Beef Production on Smallholder Farms in the Red Soils Region of China
Provedor de dados: 31
Autores: MacLeod,   Neil D.; Wen,   Shilin; Hu,   Mingwen.
The rapidly growing beef cattle herd of the Peoples Republic of China is largely carried as small numbers of animals on smallholder farms. These enterprises have traditionally focussed on cereal and vegetable crops. Limited plantings of specialised forages combined with a poor knowledge of ruminant nutrition by sm allholder farmers represent a serious challenge to establishing genuinely sustainable beef enterprises for this sector. Government policy to promote beef cattle production on smallholder farms is now focussing on the use of new forages and improved feeding practices. The paper draws on some economic insights from an Australian Centre for International Agricultural Research (ACIAR) project that is exploring options for integrating the planting and...

Autores: Franken,   Jason R.V.; Parcell,   Joseph L.; Patterson,   David J.; Smith,   Michael F.; Poock,   Scott.
The beef industry’s share of domestic meat demand continues to decline, as increasing vertical coordination in pork and poultry contribute to these industries’ ability to offer convenient, consistent, and less expensive products.  For such vertical coordination to be effective, incentives must be properly aligned so that those responsible for making the most important investments for system profitability are appropriately compensated.  This study demonstrates that cow-calf producers who invest in quality registered cattle and those who are interested in incorporating feedlot and carcass data into herd management decisions are also more interested in retained ownership.

Autores: Mattos,   Leonardo Bornacki de; Lima,   Joao Eustaquio de; Lirio,   Viviani Silva.
The analysis of market integration of agricultural commodities based on price information are limited because the effects of transaction costs are not considered in the adjustment process. The main objective of this paper was to estimate the possible transaction costs impacts on market integration of beef cattle between the states of Minas Gerais and São Paulo. It was estimated a Threshold Vector Error Correction Model (TVEC model) using monthly price data for the period from January 1972 to August 2005. The results indicated the presence of threshold cointegration implying that transaction costs have important effect on the price adjustment process.

An Economic Analysis of Genetic Information: Leptin Genotyping in Fed Cattle
Provedor de dados: 31
Autores: DeVuyst,   Eric A.; Bullinger,   Jared R.; Bauer,   Marc L.; Berg,   Paul T.; Larson,   Daniel M.
A polymorphism in the leptin gene is associated with fat deposition. Since fed cattle are often priced on a grid that considers yield and quality grades, fat deposition is an important factor in profitability. Using data from 590 crossbred steers and heifers, we simulate carcass traits to various days-on-feed and compute the associated profit under three price grids. Results indicate that leptin genotype does affect value by as much as $48 per head but has little impact on days-on-feed. Given current commercial testing fees of $40-$50 per sample, genotyping of feeder cattle appears to break even at best.

Autores: Priyanti,   Atien; Hanifah,   Vyta W.; Mahendri,   I.G.A.P.; Cahyadi,   F.; Cramb,   Rob A.
Despite its small area and intensively cropped landscape, East Java accounts for 30% of Indonesia’s beef cattle population. About two million households draw on family labour to raise cattle in backyard sheds and small enclosures, largely for cash income. The paper reports on a study in two contrasting sites – irrigated lowlands and rainfed uplands – to explore the constraints facing cattle producers in these environments and possible means to enhance their production systems and incomes. In particular, the paper focuses on the issue of feed supply and the local market that has emerged for agricultural by-products (rice straw, maize stover, and legume residues) and planted forage grasses. The research shows that intensive cattle production can provide a...

Technical Efficiency of Italian Beef Cattle Production Under a Heteroscedastic Non-Neutral Production Frontier Approach
Provedor de dados: 31
Autores: Trestini,   Samuele.
A stochastic production frontier has been estimated to measure the technical efficiency of an unbalanced panel of beef cattle farms extracted from the Farm Accountancy Data Network (FADN) databank of Veneto region in Italy. The technical efficiency is measured based on the estimation of a non-neutral and heteroscedastic production frontier. The model explains the average value of technical inefficiency as a linear function of the farm-specific variables (Battese and Coelli, 1995) and the input interaction variables (Huang and Liu, 1994). The inefficiency term is assumed to be distributed as a truncated normal with a heteroscedastic variance explained as a function of the farm-specific variables (Reifschneider and Stevenson, 1991). The average value of the...

The use of genetic knowledge is widespread in crop production but is just recently being utilized in livestock production. This study investigates the economic value to feedlots of a polymorphism in the bovine leptin gene. Previous studies indicate that this polymorphism is associated with fat deposition. Since fed cattle are often priced on a grid that considers both yield and quality grades, fat deposition is an important factor in the value and profitability of fed cattle. Using data from 590 crossbred steers and heifers, we estimate growth curves for relevant biological traits, both with and without genotypic information. Using the resulting functions, we then simulate carcass traits to various days-on-feed and compute the associated profit under three...

The financial implications of manipulating nitrogen (N) inputs and management strategies for beef production systems were assessed. One-hectare grassland farmlets were grazed to a target sward height by beef steers; herbage surplus to grazing requirements was cut for silage. Three systems were compared: ‘CN’, conventional mineral N application to a grass monoculture and broadcast slurry; ‘TN’, tactical mineral N application at fortnightly intervals to a grass monoculture with slurry injection and the early housing of cattle; ‘GC’, a mixed grass/white clover sward with no mineral N addition and slurry injection. Comparisons were made on two contrasting soil types: a freely-draining sandy loam (site 1) and a poorly drained clay (site 2). Financial budgets...

Autores: Otieno,   David Jakinda; Hubbard,   Lionel J.; Ruto,   Eric.
In this study the stochastic metafrontier method is used to investigate technical efficiency and technology gaps across three main beef cattle production systems in Kenya. Results show that there is significant inefficiency in nomadic and agro-pastoral systems. Further, in contrast with ranches, these two systems were found to have lower technology gap ratios. The average pooled technical efficiency was estimated to be 0.69, which suggests that there is considerable scope to improve beef production in Kenya

Market Signals Transmitted by Grid Pricing
Provedor de dados: 31
Autores: Johnson,   Heather C.; Ward,   Clement E.
Grid pricing improves the flow of information to producers, but market signals sent by grids may not be clearly understood. This study uses a two-stage Coefficients of Separate Determination process, four sets of fed cattle carcass data, and sensitivity analyses to identify market signals sent by grid pricing. Weight sends a stronger market signal than carcass quality characteristics such as quality and yield grade. Although grids are shaping production, market signals indicate that lower quality carcasses are penalized more than higher quality carcasses are rewarded. Sensitivity analyses suggest changes in quality and yield grade discounts have the greatest impact on market signals.

Plurality of governance on cattle ranches: case studies in Brazil
Provedor de dados: 96
Autores: Galuchi,Tharic Pires Dias; Mozambani,Carlos Ivan; Batalha,Mário Otávio.
ABSTRACT The present article investigated the plural forms of governance that have been adopted in buying and selling transactions by cattle ranches with differentiated markets. In addition, it proposes to describe and explain which determinants influence this plurality, based on the theoretical principles of transaction cost economics. The analysis was based on the observation of both upstream transactions and commitments and agreements established downstream by two ranches, both specialized in beef cattle, but with different competitive strategies. The adoption of plural forms demonstrates diverse competitive advantages, insofar as both can meet the requirements of different distribution channels or increase production capacity. The results indicated...

ABSTRACT The objective of this study was to evaluate the associations between feed efficiency and feeding behavior, growth and carcass traits in Senepol cattle. A total of 137 animals were evaluated. Of these animals, 36 males were evaluated in a second test, totaling 173 records (initial age of 466±96 days and initial weight of 426±104 kg). Residual feed intake (RFI) was calculated as the difference between observed and expected dry matter intake, estimated by regression of dry matter intake on average daily gain and metabolic body weight (BW0.75), and the animals were classified as negative (high efficiency) and positive RFI (low efficiency). The mean RFI was -0.838±0.078 and 0.797±0.075 kg DM day-1 for negative and positive RFI animals, respectively,...

Feed intake and average daily gain (ADG) in Nellore cattle were determined to calculate residual feed intake in two performance tests: first during the growth phase (RFIgrowth) and then during a measurement of the methane emission phase (RFImet). During the RFIgrowth test, 62 males and 56 females were classified as low-, medium-, and high-RFI. Enteric methane emission was measured in 46 animals; 23 males used for RFImet measurement plus 23 females (22 low-RFIgrowth and 24 high-RFIgrowth). Diet consisted of Brachiaria brizantha cv. Marandu hay (445 g/kg DM) and concentrate (555 g/kg DM). During the RFIgrowth and RFImet phases, DMI was lower in the animals with low RFI, with no difference in ADG. Residual feed intake was -0.359 and 0.367 kg DM/d for low- and...

Autores: Silva,Luiz Henrique Oliveira; Bonilha,Sarah Figueiredo Martins; Branco,Renata Helena; Cyrillo,Joslaine Noely dos Santos Gonçalves; Mercadante,Maria Eugênia Zerlotti.
ABSTRACT The objective of this study was to develop accurate regression equations to predict body composition of Nellore cattle using chemical composition of the 9th, 10th, and 11th ribs and to evaluate the models proposed by analyzing mean and linear bias. Sixty-seven Nellore bulls were slaughtered and slaughter body weight (SBW), hot carcass weight (HCW), and 9th-, 10th-, and 11th-rib-cut weight (RCW) were measured. Empty body composition was obtained after grinding, homogenizing, sampling, chemical analysis, and pooling (blood, skin, head + feet, viscera, and carcass). Chemical components were determined in rib cut, carcass, and empty body: protein (RCP, HCP, and EBP), fat (RCF, HCF, and EBF), ash (RCA, HCA, and EBA), and water (RCWt, HCWt, and EBWt)....

Abstract We investigated whether a panel of molecular markers previously associated with temperament has an effect on live growth traits. Phenotypic data from 412 Charolais cows categorized according to their age in adult and young cows were used to determine Pearson's correlations between birth (BW), weaning (WW), and yearling live (YW) weight and temperament traits (measured as exit velocity [EV] and temperament score [TS]). For association analysis, selective genotyping of a group of 80 cows identified as the most docile and temperamental were genotyped with a 151-SNP (single-nucleotide polymorphisms) panel of molecular markers previously associated with temperament. Significant Pearson's correlations between birth weight and weaning weight and the two...

Autores: Menezes,Gilberto Romeiro de Oliveira; Torres,Robledo de Almeida; Torres Júnior,Roberto Augusto de Almeida; Silva,Luiz Otávio Campos da; Gondo,Andrea; Euclydes,Ricardo Frederico.
To provide information that can contribute to the genetic evaluation and selection in Tabapuã cattle, genetic parameters were estimated for growth traits using a multi-trait animal model. (Co)variance components were estimated by a Bayesian approach using the Gibbs Sampler. Moderate and similar responses to selection are expected when selecting for weights at the four ages evaluated, since the direct heritability estimates were similar and of average magnitude (0.18 to 0.19). The direct and maternal additive genetic correlations between all pairs of weights were higher than 0.70, indicating a high degree of association between the four traits. This suggests that using any of them as selection criteria will result in correlated response in the others and...

A simulation model implemented in the programming software Delphi XE® was applied to evaluate sex selection in bovine. The hypothesis under investigation was that a dynamic model with stochastic and deterministic elements could detect the sexed semen technique to minimize pregnancy cost and to determine the adequate number of recipients required for in vivo (ET) and in vitro embryo production (IVP) in the proposed scenarios. Sex selection was compared through semen sexed using flow cytometry (C1) and density gradient centrifugation techniques (C2) in ET and IVP. Sensibility analyses were used to identify the adequate number of recipients for each scenario. This number was reinserted into the model to determine the biological and financial values that...

The objective of the present study was to outline the profile of managers and inseminators involved in beef cattle artificial insemination programs to characterize the management processes involved in this activity. Additionally, by interviewing managers and inseminators, it was searched to detect particularities concerned to personal life and work that can be used to evaluate the quality of life of inseminators on farms. The open questions were analyzed by frequency of answer, after being grouped by similarity. Accordingly to the results, managers associate the concept of human resource management to work supervision, mainly, prioritizing technical factors such as professional experience and indexes in the selection processes, although problems in...

The objective of this study was to estimate the heritability of probability of early pregnancy (PEP) and scrotal circumference (SC) and the genetic correlation between these traits in Nellore cattle. PEP records from 11,696 Nellore females born between 1983 and 2001 were analyzed. PEP was assumed to be one for females that effectively bred in the herd (19.84%) and zero for those discarded before first calving (80.16%). The model used to study PEP included the effects of contemporary group, age of dam at calving and heifer weaning age, direct additive genetic effects, and residual effects. For SC, 9335 records were analyzed considering the effect of contemporary group, direct additive genetic effects and residual effects. Covariance components were...

Autores: Mombach,Mircéia Angele; Carvalho,Perivaldo de; Cabral,Luciano da Silva; Rodrigues,Renato de Aragão Ribeiro; Torres,Renato Cristiano; Pereira,Dalton Henrique; Pedreira,Bruno Carneiro e.
ABSTRACT This study aimed to evaluate the frequency and intensity of GreenFeed (GF) use by Nellore steers using different attractants in pastures of integrated systems. The attractant protein supplement and Tifton bermudagrass pelleted hay flavored with vanilla were evaluated over a period of 15 days. The pelleted hay stimulated the animals to stay longer in the equipment (24.23 s), with 8% more visits in intervals longer than 30 s in contrast to protein supplement. This indicates that pelleted hay flavored with vanilla is a potential attractant to encourage Nellore steers to visit GF in grazing systems.

Autores: Azevêdo,José Augusto Gomes; Valadares Filho,Sebastião de Campos; Pina,Douglas dos Santos; Chizzotti,Mario Luiz; Valadares,Rilene Ferreira Diniz.
The study was carried out to develop and to evaluate new equations to predict dry matter intake (DMI) of Nellore and Zebu-crosses cattle using meta-analysis procedure. The data used to estimate the parameters were collected from independent performance experiments using growing and fattening Nellore and Zebu-crosses cattle, and they were compiled from 561 experimental units. Before proposing an equation to predict DMI, it was observed that the genetic group was a source of statisticaly significant variation. Therefore, equations to predict dry matter intake in the Zebu-Crosses and Nellore cattle were independently developed. The regression equations for Zebu-crosses cattle were: DMI = -2.6098 + 0.08844BW0.75 + 4.4672ADG - 1.3579ADG2 and DMI = -1.0094 +...

Autores: Marinho,Kedma Nayra da Silva; Freitas,Alfredo Ribeiro de; Falcão,Alencariano José da Silva; Dias,Francisca Elda Ferreira.
Growth curves of Nellore cows were estimated by comparing six nonlinear models: Brody, Logistic, two alternatives by Gompertz, Richards and Von Bertalanffy. The models were fitted to weight-age data, from birth to 750 days of age of 29,221 cows, born between 1976 and 2006 in the Brazilian states of Acre, Amapá, Amazonas, Pará, Rondônia, Roraima and Tocantins. The models were fitted by the Gauss-Newton method. The goodness of fit of the models was evaluated by using mean square error, adjusted coefficient of determination, prediction error and mean absolute error. Biological interpretation of parameters was accomplished by plotting estimated weights versus the observed weight means, instantaneous growth rate, absolute maturity rate, relative instantaneous...

Provedor de dados: 96
Autores: Contreras,Víctor Inocencio Pacheco; Bracamonte,Gaspar Manuel Parra; Bustamante,Luis Arístides López; Medina,Víctor Ricardo Moreno; Rincón,Ana María Sifuentes.
To determine the effects of a number of non-genetic factors on milk components and estimate their indirect relationships with weaning weight (WW205), the percentages of protein, fat, lactose and solids non-fat in Charolais cows from Mexico were estimated. Lactation period (LP) and calving season (CS) had significant effects on protein and fat, whereas lactose and solids non-fat were only affected by the LP. Sire line and age of the dam had significant effects on calf birth weight, while CS affected WW205. Residual correlations between milk components and WW205 suggest a low but significant correlation with lactose. These results demonstrate the importance of several non-genetic factors on the composition of milk from Charolais cows managed under extensive...

ABSTRACT The objective of this survey was to identify what mycotoxins were present in ingredients used in diets offered to beef cattle in feedlots and their concentrations. The survey covered 30 Brazilian feedlots located in the five major beef-producing states. Samples of total mixed ration (TMR) and ingredients were collected and analyzed for mycotoxin using ultra-performance liquid chromatography coupled to tandem mass spectrometry. Mycotoxin concentrations were further interpreted according to known species-specific sensitivities and normalized according to the principles of toxic equivalent factors (risk equivalent quantities - REQ) expressed in µg kg−1 of aflatoxin B1-equivalent. Forty percent of the visited feedlots had apparent fungi in TMR....

Autores: Silva Neto,Waldemiro Alcântara da; Bacchi,Mirian Rumenos Piedade.
With the considerable growth of beef production in Brazil and the growth in beef exports as a backdrop, the main objective of this study is to identify the factors responsible for the excellent performance of this agribusiness sector. Conducting this study required the construction of a theoretical model that was capable of supporting the specification of the adjusted econometric model using vector autoregression with identification by the Bernanke process. The findings show that the main determinant of beef cattle growth and Brazilian beef exports is increased animal stock. Furthermore, productivity has a positive, albeit more modest, effect on beef production and exports. The results show that the increase of the number of cattle reduces costs to the...

Considerable resources have been allocated to support research in the development of non-invasive and non-destructive techniques for carcass composition and quality evaluation. Ultrasonography is a reliable and relatively low-cost technique that can be used. In the present study, real-time ultrasonography was used to predict ribeye area (REA) and subcutaneous fat thickness (FT) in live animals as compared to carcass measurements. Animals used were 115 yearling bull calves (initial body weight, 329 kg), kept under feedlot conditions, of four genetic groups (30, ½ Angus x Nellore; 30, ½ Canchim x Nellore; 30, ½ Simmental x Nellore, and 25 Nellore), and two finishing frame sizes (small and large). Four ultrasonographic measurements were taken every 28 days...

Mixed-effects growth curves in the valuation of Nellore sires
Provedor de dados: 63
Autores: Giolo,Suely Ruiz; Henderson,Robin; Demétrio,Clarice Garcia Borges.
Cattle breeding programmes need objective criteria in order to evaluate and subsequently improve production systems. This work uses a logistic growth curve model for evaluating sires based on their progeny weight measured repeatedly over time. The parameters of the curve are described as a linear function of fixed and random effects. A Bayesian approach is used for the estimation. Analysis of the weights recorded on animals of the Nellore breed shows that growth curve models with fixed and random effects can be useful to evaluate and selecting sires.

Hanging beef carcasses in different configurations in the cooler affect some carcass muscle tenderness. Forty Nellore steer carcasses (ten per day) were chosen at random in a federally inspected slaughter plant and hanged alternate left and right sides either in the traditional way by the hindquarter (HQ) or by the forequarter (FQ) also called "tenderbife". Carcasses were selected from steers up to 30 months old and had an average hot carcass weight of 244.1 kg. These carcasses were chilled for 48 hours, when samples from the Longissimus dorsi (LD) at the 12th rib and the Biceps femoris (BF) at the P8 site were removed, kept under refrigeration (0-2ºC) for five days and frozen for future analysis.

This experiment aimed to investigate the effect of Mao pomace (MP) levels on degradability and rumen gas production using in vitro gas production techniques. The experiment was designed by a completely randomized design (CRD). The dietary treatments were supplemented by MP at 0, 4, 8, 12, 16 and 20 mg with 0.5 g of roughage and concentrate ratio at 60:40. It was found that gas production from the insoluble fraction (b) had no effect (p&gt;0.05) by MP supplementation, while potential extent of gas production (a+b) and gas production rate (c) were significantly different among treatments. Cumulative gas production at 96 h was not affected by MP supplementation (p&gt;0.05). Moreover, in vitro dry matter degradability (IVDMD) was not different among groups...

Autores: Bresolin, Tiago; Everling, Dionéia Magda; Rorato, Paulo Roberto Nogara; Braz, Camila Urbano; Breda, Fernanda Cristina.
The aim of this study was to assess the occurrence of genotype-environment interaction, as well as its effects on the magnitude of genetic parameters and the classification of Nellore breeding bulls for the trait adjusted weight at 205 days (W205) on Southern Brazil. The components of (co)variance were estimated by Bayesian inference, using a linear-linear animal model in a bi-trait analysis. The proposed model for the analyses considers as random the direct additive genetic and maternal effects and residual effects, and as fixed effects the contemporary groups, sex, season of birth and weighing, and calving age as covariable  (linear and quadratic effects). The a posteriori mean estimates of the direct heritabilities for W205 in the three States varied...

Minerals play an important role in the cattle metabolism with great impact in productive and reproductive performance of animals raised on extensive grasslands. At present, there is a lack of information concerning mineral deficiency throughout the analysis of biological fluids in Rio Grande do Sul State (southern Brazil). The Central Valley region of this State is characterized by extensive production on natural pastures with poor mineral supplementation. The low levels of minerals found by previous studies on pastures in this area motivated this research. The aim of the present work was to detect possible mineral deficiencies in beef cows by determining concentrations of minerals in biological fluids and in pasture. There were determined concentrations...

Autores: Vinholis,Marcela de Mello Brandão; Carrer,Marcelo José; Souza Filho,Hildo Meirelles de.
ABSTRACT: This paper aimed to identify the determinants of beef traceability adoption at farm level in São Paulo State, Brazil. A sample survey of 32 farmers who adopted the European Union certified traceability and 52 other farmers who did not adopt traceability provided data to test hypotheses on determinant factors. Three binomial logit models were used in the analysis. Results suggested that capital-intensive livestock production system, high scale production, access to specialized information and high level of human and social capital play significant role in the adoption decision.

ABSTRACT: The demand for beef cattle with specific traits is evident from sales in auctions. While purchasing, buyers consider individual traits (e.g., muscularity, frame, racial composition, and weight) as predictors of quality, and adjust their bids according to their preferences. The present study aimed to evaluate the effect of phenotypic and racial characteristics in determining the final sale price of calves of beef cattle in official auctions at the western border of the state of Rio Grande do Sul, Brazil. Five-hundred and seven lots of calves sold in calf auctions from five cities on the western border of Rio Grande do Sul were evaluated. The assignment of visual scores was based on their genetic group, frame, muscularity, and coat. Analysis of...

Evaluation of "Pampa-Corte" simulation model in different beef cattle fattening systems in Spain
Provedor de dados: 65
Autores: Silveira,Vicente Celestino Pires; Casasús,Isabel; Blanco,Mireia; Joy,Margalida; Bernués,Alberto.
The Pampa-Corte model was developed to simulate the growth of beef cattle in grazing systems in a dynamic and mechanistic way. It was validated under Brazilian conditions. This paper aims to verify the performance of the model in conventional and alternative beef cattle finishing systems in Spain. An experimental dataset of 21 Parda de Montaña calves of similar age and weight at weaning was used to evaluate the model. They were slaughtered individually on reaching 450kg liveweight. The model considered genetic group maturity rather than breed, in order to adjust growth parameters, once Parda de Montaña breed is not contemplated by AFRC (1993). Parameters from late maturing group were initially used considering adult animal size of Parda de Montaña animals;...

ABSTRACT: Mature weight (MW) of cows is related to the costs of their production. Usually, cows with moderate MW are more efficient in challenging environments, such as those available in the production systems in Brazil. In the present study, the selection index comprises the following traits: conformation, finishing precocity, musculature at weaning (WC, WP, WM) yearling (YC, YP and YM), scrotal circumference at yearling (SC), days to gain 160kg from birth to weaning (D160) and 240kg after weaning (D240). This are related to birth weight gain at weaning (WG) and from weaning to yearling (YG). The mature (MW) and birth weight (BW) traits were not considered in the selection index. The aim of this study was to estimate the values for the genetic trends...

Autores: Fabricio,Edom de Avila; Pacheco,Paulo Santana; Vaz,Fabiano Nunes; Lemes,Daniel Batista; Camera,Angelina; Machado,Gabriella Ibarra Ocaña.
ABSTRACT: The objective of this study was to evaluate various financial indicators, estimated deterministically (considering historical quotes twelve consecutive years - 2003 to 2014), on the economic feasibility of finishing steers commercialized with different weights, using the simulation technique. Performance data steers were simulated with average initial weight of 350kg, fed in feedlot and slaughtered with 410, 440, 470, 500, 530, 560 and 590kg. The feeding period varies from 46 to 185 days, respectively. Based in various economic indicators, the viability of the investment decreased linearly according to the increase in slaughter weight. The coefficient of simple linear regression and means from lowest to highest slaughter weight were,...

Three short tandem repeats (STRs), BMS1074, BM1500, IDVGA-51, and three single nucleotide polymorphisms (SNPs), LEPSau3AI (A/B), LEPSau3AI (+/-) and LEPKpn2I linked to the LEP gene were investigated to verify associations with productive performance in postpartum cows of two beef cattle breeds, Aberdeen Angus (AA, n=98) and Charolais (C, n=83). After polymerase chain reaction, STRs were analyzed by vertical electrophoresis and SNPs in agarose gel after endonucleases cleavage. In AA herd 79% of BMS1074*151 carriers had a lower average daily weight gain (ADG) when compared with the population mean daily weight gain (103g), while 62% of BMS1074*151 non-carriers presented a higher ADG (P&lt;0.01); AA animals with at least one BMS1074*151 allele showed a ADG...

The joint analysis of indicators of the investment project is very relevant in making decisions, resulting in more consistent information regarding risk assessment and its confrontation with the possibility of return. This research aimed to evaluate the economic feasibility of Red Angus young steers finished in feedlot, slaughtered at 340, 373, 396 or 430kg with use of various financial indicators, marketed with or without bonus. The purchase of feeder cattle and feeding were variable costs with a higher share in the total cost. In the analysis with bonus, the regression analysis to gross margin, net margin, net present value, benefit:cost index and additional return on investment showed quadratic behavior, with the point of maximum at 406kg (R$ 185.17),...

Autores: Guimarães,Adriano de Souza; Souza,José Camisão de; Andrade,Ivo Francisco de; Freitas,Rilke Tadeu Fonseca de; Cirillo,Marcelo Ângelo.
The objective was to characterize cattle slaughtered from the region of Lavras - MG. In the public abattoir 720 bovines were identified and slaughtered from September 20th through November 20th of 2004. Variables such as: genetic origin, live weight, body condition, age, and sex were studied. At arrival, animals were weighed and classified according to their genetic origin. Before slaughter, their body condition (BC) was determined on a 1 - 9 scale. Reproductive status was observed during scratch and evisceration: castrated male, MC; intact male, MI; pregnant female, FG; and Non-pregnant female, FNG. Age was determined by the count of the permanent incisive teeth (p.i.t.). Most animals slaughtered during the survey were male, with predominance of the...

Provedor de dados: 64
Autores: Liz,Diego Melo de; Ribeiro Filho,Henrique Mendonça Nunes; Andrade,Ederson Americo de; Nardi,Camila Zardo de; Miguel,Marcolino Frederico; Almeida,Edison Xavier.
Relatively short grazing periods in a pure legume pasture can be an alternative for increasing animal performance in medium-quality tropical pastures. Thus, the aim was to evaluate the herbage intake and animal performance of steers grazing dwarf elephant grass (Pennisetum purpureum Schum. cv. BRS Kurumi) with two access times [2 h (07:00 - 9:00) and 6 h (07:00 - 13:00)] to an area of forage peanut (Arachis pintoi cv. Amarillo). Twelve steers (219 ± 28.8 kg LW) were divided into four groups and assessed during three consecutive grazing cycles, from January to March 2013. The crude protein and neutral detergent fiber contents were 158 and 577 g/kg dry matter (DM) for dwarf elephant grass and 209 and 435 g/kg DM for forage peanut, respectively. The...
