Advantages and challenges for Brazilian export of frozen beef R. Bras. Zootec.
Pereira,Paulo Rodrigo Ramos Xavier; Barcellos,Júlio Otávio Jardim; Federizzi,Luiz Carlos; Lampert,Vinícius do Nascimento; Canozzi,Maria Eugênia Andrighetto; Marques,Pedro Rocha.
The objectives of this research were to analyse data on the international market of frozen boneless beef and to classify its participants into groups according to their trade relationships, identifying the main factors that influence the preference of a country to beef from a determined supplier country. International beef trade is composed of two markets: in one of them, the relationships between supplier and client depend on the lowest price, and Brazil is found in favorable conditions; and the other, the relationships are preferably based on the sanitary quality of the herd and traceability systems recognized by the purchaser, to which Brazilian participation is low.

Reinher,Cristiane; Barcellos,Júlio Otávio Jardim; Peripolli,Vanessa; Prates,Ênio Rosa; Canozzi,Maria Eugênia Andrighetto.
It was evaluated in this work the effect of calving sub-season on the pregnancy rate of 7,726 multiparous Hereford beef cows grazing on natural pastures in southern Brazil, from 1994 to 2007. Calving sub-season periods were divided in 20-day intervals from August 12th to 31st; from September 1st to 20th; from September 21st to October 10th; from October 11th to 31st; from November 1st to 20th. Calving in each sub-season and pregnancy rate (PR) were analyzed by the Chi-square test. Overall means of each sub-season were 92.7% (from August 12th to 31st), 90.6% (from September 1st to 20th), 82.1% (from September 21st to October 10th), 77.7% (from October 11th to 31st), and 70.6% (from November 1st to 20th). Calving sub-season significantly influenced pregnancy...

Pereira,Paulo Rodrigo Ramos Xavier; Barcellos,Júlio Otávio Jardim; Gründling,Roberta Dalla Porta; Canozzi,Maria Eugênia Andrighetto; McManus,Concepta; Lopes,Rúbia Branco.
The objective of this study was to measure and classify the international beef trade. For this, data related to the international chilled boneless beef (CBB) trade, the major and most important market, were analyzed. Producing countries were classified into groups according to their trade relations, and the main factors that influenced one country to prefer to import CBB from a specific exporting country were analyzed. The results revealed four markets related to client demands with regard to the sanitation and traceability of beef products. Furthermore, extrinsic characteristics of the product are discussed, such as a productive system that aims to minimize environmental impacts and to value animal welfare and respect for social demands. The markets that...

Barcellos,Júlio Otávio Jardim; Abicht,Alexandre de Melo; Brandão,Fernanda Scharnberg; Canozzi,Maria Eugênia Andrighetto; Collares,Fernando Carbonari.
The objective of this study was to determine consumers understanding of beef traceability, identifying how consumers value this meat and traceability elements to be presented on retail shelves. The method used in this study was a survey through the internet applying the Sphinx software. The sample consisted of 417 consumers, mostly living in Porto Alegre, Brazil. Consumers are aware of certified beef, consider it important, but this is not a demand. As to traced beef, most consumers (62.4%) are in favor of mandatory traceability of beef cattle in Brazil, but 86.6% disagree with the destination of traced beef only to the foreign market. The majority of people are willing to pay more for traced beef and consider traceability a market opportunity, used as a...

Development and application of a bioeconomic efficiency index for beef cattle production in Rio Grande do Sul, Brazil R. Bras. Zootec.
Lampert,Vinícius do Nascimento; Barcellos,Júlio Otávio Jardim; Kliemann Neto,Francisco José; Canellas,Leonardo Canali; Dill,Matheus Dhein; Canozzi,Maria Eugênia Andrighetto.
An index was developed to estimate the bioeconomic efficiency of production systems, identifying alternative scenarios that could improve their efficiency, and building isoefficiency relations in beef cattle production systems in Rio Grande do Sul. The concept of return on investment was used to develop the indicator. Scenarios regarded as efficient showed values higher than 3. The bioeconomic efficiency index for beef cattle production in the theoretical reference scenario was considered inefficient. At least four modifications in the variables method made it a bioeconomically efficient activity. These circumstances were studied using sensitivity analyses, with theoretical changes in the scenarios by changing variables two by two, while the others were...

Manejo da comercialização em leilões e seus efeitos no preço de bezerros de corte R. Bras. Zootec.
Christofari,Luciana Fagundes; Barcellos,Júlio Otávio Jardim; Braccini Neto,José; Oaigen,Ricardo Pedroso; Canozzi,Maria Eugênia Andrighetto; Wilbert,Cássio André.
Avaliou-se o processo de comercialização de 1.757 lotes de bezerros, totalizando 28.495 animais, incluindo a ordem e o tempo de permanência em pista, as estratégias de divulgação aos compradores e uniformização dos lotes, o preço final (R$/kg de PV) e o número de lances. O modelo proposto foi eficiente em cenários desfavoráveis à atividade de cria. Em períodos de grande oferta de bezerros e preços baixos, todas as variáveis estudadas podem influenciar o preço final por quilograma de peso vivo, o que indica que alguns aspectos fora do controle do produtor, mas bem próximo dele, podem influenciar o valor recebido, portanto, são importantes no acompanhamento do processo de comercialização dos animais.

Modelling beef cattle production systems from the Pampas in Brazil to assess intensification options Scientia Agricola
Lampert,Vinícius do Nascimento; Canozzi,Maria Eugênia Andrighetto; McManus,Concepta Margaret; Dill,Matheus Dhein; Oliveira,Tamara Esteves de; Mercio,Thomaz Zara; Teixeira,Odilene de Souza; Barcellos,Júlio Otávio Jardim.
ABSTRACT Traditional livestock productivity is hard to estimate, since it depends on a gamut of animal production indicators that are difficult to measure for many farms. Thus, we propose an analytical method for estimating productivity and understanding the importance of animal production indicators under different full-cycle cattle production systems in Brazil. To evaluate the impact of these indicators, equations were derived from a comutational model of herd evolution for estimating the output parameters of the system as follows: productivity per hectare (PH) and offtake rate (COR), as a function of the indicators; calving rate (CR), mating age (AM), age of slaughter (AS) and stocking rate (SR). For this analysis, twenty-seven scenarios (simulation...

Menezes,Adriana Morato; Louvandini,Helder; Esteves,Geisa Isilda Ferreira; Dalcin,Luciana; Canozzi,Maria Eugênia Andrighetto; Barcellos,Júlio Otávio Jardim; McManus,Concepta.
The objective of this study was to evaluate performance and biometrics of lambs fed different sources of forage. Twenty-four six-month-old Santa Inês female lambs were randomly allocated to four experimental diets and housed in individual stalls. They weighed on average 26.35±0.20 kg. The diets were coast cross hay (HAY), cassava hay (CAS), dehydrated by-product of pea crop (PEA) and saccharin (SAC). The diets were formulated with the same amount of protein and energy with fixed levels of forage (60%) and concentrate (40%). Adaptation to the diet took 7 days, with 45 days on experiment. Weights and biometric measurements were obtained every fortnight and feed intake three times a week. Rights half-carcasses were weighed and sectioned into retail cuts, rib,...

ABSTRACT This study was intended to evaluate body size structure and growth parameters of crossbred heifers fed at four nutritional levels to achieve puberty earlier. Animals were classified depending on their level of crossing between Nelore and Hereford and subjected to four nutritional levels (kg day−1) as follows: 0.5 (light; n = 32), 0.75 (medium; n = 32), 1.00 (high; n = 29), and 1.25 (very high; n = 27). Heifers at puberty and at weaning were individually classified for growth parameters. The fat thickness and longissimus muscle area throughout the experimental period were determined by ultrasonography. The height, heart girth, frame, and weight:height ratio were variables used to evaluate body traits. Univariate analysis of variance using the GLIM...

Canozzi,Maria Eugênia Andrighetto; Marques,Pedro Rocha; Teixeira,Odilene de Souza; Pimentel,Concepta Margaret McManus; Dill,Matheus Dhein; Barcellos,Júlio Otávio Jardim.
ABSTRACT: The objective of this study was to evaluate the bioeconomic efficiency of beef cattle production systems in the south of Brazil. A survey was conducted with 33 beef cattle farmers operating with complete cycle production systems in areas larger or equal to 900 ha. Answers were classified in two drivers, technology (TEC) and management (MAN), which were separated into subfactors with their respective components. Multiple correspondence analysis, Tukey test, cluster analysis, and Pearson correlation were the statistics procedures. The TEC components were above normal for Brazilian farmers, but the gross margin is still lower than that needed to generate financial resources for a proper remuneration of cattle farmer. Farmers were classified into...
