Ability of non-linear mixed models to predict growth in laying hens R. Bras. Zootec.
Galeano-Vasco,Luis Fernando; Cerón-Muñoz,Mario Fernando; Narváez-Solarte,William.
In this study, the Von Bertalanffy, Richards, Gompertz, Brody, and Logistics non-linear mixed regression models were compared for their ability to estimate the growth curve in commercial laying hens. Data were obtained from 100 Lohmann LSL layers. The animals were identified and then weighed weekly from day 20 after hatch until they were 553 days of age. All the nonlinear models used were transformed into mixed models by the inclusion of random parameters. Accuracy of the models was determined by the Akaike and Bayesian information criteria (AIC and BIC, respectively), and the correlation values. According to AIC, BIC, and correlation values, the best fit for modeling the growth curve of the birds was obtained with Gompertz, followed by Richards, and then...

Addition of Amylase from Aspergillus Awamori to the Diet of Broiler Chickens Rev. Bras. Ciênc. Avic.
Morgado,HS; Cysneiros,CSS; Sousa,CM; Stringhini,JH; Ulhoa,CJ; Silva,AS; Fabino Neto,R; Freitas,PVDX; Oliveira,HP; Batista,LHC.
ABSTRACT Two experiments were performed to evaluate the hematological and blood biochemistry parameters, biometry of digestive organs, enzyme activities, protein content and absolute weight of the pancreas of broilers fed pre-starter and pre-starter diets supplemented or not with amylase from Aspergillus awamori. In total, 120 male Cobb chicks were housed in heated cages in each experiment. A completely randomized experimental design, with two treatments (feed with and without amylase) and six replicates per treatment of 10 birds each was applied. The data were subjected to analysis of variance using the F-test at 5% probability level. The dietary amylase addition did not affect hematological and blood biochemistry parameters and the biometry of the...

Amino acid digestibility and poultry feed formulation: expression, limitations and application R. Bras. Zootec.
Bryden,Wayne L.; Li,Xiuhua.
The nutritional value or quality of dietary proteins used for poultry feed formulation varies: amino acid availability is an important measure of protein quality. Determination of ileal digestibility values has become the preferred method for estimating amino acid availability. This review discusses the different approaches to the expression of digestibility results, including correction for endogenous loss and the derivatisation of standardised values. Sources of variation in values include, the assay protocol, anti-nutritional factors in feedstuffs and feed milling. Feed formulating with ileal digestibility values should allow higher dietary inclusion levels of protein feedstuffs of lower quality provided that values of different feedstuffs are additive,...

An alternative for antibiotic se in poultry: probiotics Rev. Bras. Ciênc. Avic.
Edens,FW.
Over the past 50 years, there has been increasing amounts of antibiotics used prophylactically and as growth promoters. Today, there is a consumer and governmental outcry to eliminate that practice from poultry and livestock production. Evidence has been accumulated to show that there is a link between risk of zoonotic disease and growth promoting antibiotic usage in livestock and poultry. Therefore, alternatives to the use of growth promoting antibiotics must be found to promote growth or production at or near the genetic potential of the modern day broiler, turkey, and egg producer. The use of probiotics has many potential benefits and include modified host metabolism, immuno-stimulation, anti-inflammatory reactions, exclusion and killing of pathogens in...

Assessment of immunity against avian colibacillosis induced by an aroA mutant containing increased serum survival gene in broilers BJM
Salehi,Taghi Zahraei; Tabatabaei,Saeid; Karimi,Vahid; Fasaei,Bahar Nayeri; Derakhshandeh,Abdollah; Jahromi,Omid Ali Nekoui.
Colibacillosis is an important disease in the poultry industry which causes serious economic damages. As it is suggested that vaccination is one of the means to control colibacillosis, we tried to investigate the vaccine potential of a ΔaroA derivative of an O78:K80 avian pathogenic Escherichia coli containing increased serum survival gene. 490 chicks were selected as follows: For assessment of virulence of ΔaroA mutant, 30 chicks were divided into three groups and injected with 0.5ml of PBS or bacterial suspension containing either10(7)colony forming units (CFU) of mutant or parent strains via subcutaneous route. Macroscopic lesions and mortality rate were recorded in different groups during the week after challenge. For assessment of safety and...

Assessment of serological response of chickens to Salmonella Gallinarum and Salmonella Pullorum by Elisa Rev. Bras. Ciênc. Avic.
Oliveira,GH de<A NAME="nt01a"></A>; Berchieri Júnior,Â; Montassier,HJ; Fernandes,AC.
This study was done to assess an enzyme-linked immunosorbent assay (ELISA) to detect chicken serological response against Salmonella enterica serotypes Gallinarum and Pullorum. The assays have used soluble bacterial proteins of Salmonella Gallinarum strain 9 (AgSG) as detecting antigen and peroxidase and alkaline phosphatase conjugates. According to the results, the antigen, sera and conjugate concentrations were optimized. In addition, the assay using alkaline phosphatase and peroxidase conjugates was helpful to distinguish positive serological reaction to serotypes Gallinarum and Pullorum from Enteritidis.

Broiler-Housing Conditions Affect the Performance Rev. Bras. Ciênc. Avic.
Mesa,D; Muniz,E; Souza,A; Geffroy,B.
ABSTRACT In the last decades animal production has considerably increased worldwide to sustain an ever-growing human population. Among animal reared for consumption purposes, chickens are undoubtedly one of the most successful, mainly due to their rapid growth rate. The development of broiler farming has been accompanied in recent years by a substantial attention to animal welfare. This study is aimed at assessing the effects of different housing conditions on both feed conversion ratio and mortality of male broiler flocks through a large-scale study (more than 100 million birds) involving 977 farms belonging to one major producer. For this, we evaluated nine features of the housing system using a linear model with random effect. The features were:...

Campylobacter sp in organs and meconium of day-old broiler chicks derived from naturally infected breeder hens Rev. Bras. Ciênc. Avic.
Fonseca,BB; Soncini,RA; Vieira,FL; Siqueira,MS; Guimarães,AR; Beletti,ME; Rossi,DA.
Campylobacter sp is an important agent that causes foodborne infection, particularly in food of poultry origin. Therefore, the efficient control of the transmission routes in chicken farms is of outmost importance to prevent it from spreading. In chicken farms, the main transmission route of this microorganism is horizontal, as the vertical route continues to be the object of inconclusive researches. The objective of this study was to verify the presence of Campylobacter sp in breeder hens, meconium, and other organs of day-old chicks derived from these breeders in order to obtain information on vertical transmission. Microbiological analyses were performed, using cloacal swabs from 279 breeder hens. Positive breeders were segregated, and the presence of...

COMO construir instalações para aviários: programa 31: Nordeste/Vale do Jequitinhonha. Infoteca-e
Esta semana o Prosa Rural traz pra você orientações sobre as principais medidas que devem ser tomadas para a construção de um aviário - um galinheiro, voltado para a criação de ave caipira. A escolha do local, o tamanho, o material, as divisões necessárias são aspectos importantes ao se iniciar uma criação de galinha caipira. As instalações apropriadas são fundamentais para garantir o conforto térmico das aves, principalmente em zonas que apresentam temperatura e umidade elevadas. Participa do programa, o zootecnista Robério Sobreira, da Embrapa Meio-Norte.

Control of Newcastle Disease in Village Chickens AgEcon
Centre for International Economics.
Between 1983 and 1992, the Australian Centre for International Agricultural Research (ACIAR) invested A$3 million in research to find a vaccine that could provide protection from Newcastle disease in chickens and be applied in village environments in developing countries. A further $160 000 was invested in follow up projects which ended in 1996. Village chickens often provide the only source of protein to poor villagers living in remote areas and Newcastle disease frequently devastates unvaccinated village flocks. The ACIAR-sponsored research was highly successful in developing a heat resistant vaccine (HRV4) which could be readily used in the field by coating it onto chicken feed. The vaccine was commercialised by an Australian company which subsequently...
