1. Performance, Growth Curves and Carcass Yield of Four Strains of Broiler Chicken
ABSTRACT The objective of this study was to evaluate the performance, carcass yield and growth curves of different commercial strains of broiler chicken. 2400 day-old chicks, males and females of the Cobb500, RossAp95, Hubbard Flex and a new Francesa line were used. The birds were distributed in a completely randomized design in a factorial arrangement 4x2 (

3. Serological response against bovine herpesvirus and bovine viral diarrhea virus induced by commercial vaccines in Holstein heifers
RESUMO: A vacinação é utilizada como estratégia para a prevenção e controle das doenças reprodutivas, causadas pelos vírus da diarreia viral bovina (BVDV) e herpesvírus bovino tipo 1 (BoHV-1), entretanto, as diversas composições de vacinas comerciais devem ser avaliadas quanto a sua eficiência protetiva mediada por anticorpos (Acs). O objetivo de

5. Análise evolutiva da morfologia e da irrigação do timo de javalis (Sus scrofa Linnaeus, 1758)
RESUMO Objetivou-se descrever comparativamente as artérias responsáveis pela irrigação dos lobos tímicos cervicais e torácicos dos javalis, determinando-se também as características morfológicas do referido órgão nessa espécie, a ponto de correlacioná-las evolutivamente com os demais representantes da família Suidae. Os lobos tímicos cervicais

6. Antimicrobial Resistance and Molecular Characterization of Salmonella Enterica Serotypes Isolated from Poultry Sources in Brazil
ABSTRACT Salmonella spp. remain among the most important agents of foodborne diseases worldwide. The importance of Salmonella spp. in public health is linked to their wide range of antimicrobial resistance and to their pathogenicity and virulence in both human and animal hosts. The aim of this study was to determine the antimicrobial resistance patterns for

7. DESEMPENHO ZOOTÉCNICO DE JUVENIS DE TILÁPIAS DO NILO (Oreochromis niloticus) ALIMENTADOS COM CEPAS PROBIÓTICAS E SUBMETIDOS A DESAFIO SANITÁRIO
Resumo O surgimento de doenças ocasionadas pelo estresse durante o cultivo de juvenis vem tornando-se comum devido à intensificação dos sistemas de produção, ocorrendo elevada mortalidade e prejuízos econômicos ao produtor. Mediante esse contexto, os probióticos que são um conjunto de micro-organismos vivos, estão sendo utilizados devido à sua ca

8. Adjustment of nonlinear models and growth parameters and body nutrient deposition in meat-type and laying quail
ABSTRACT The objective of this study was to determine the adjustment quality of non-linear models and estimate the growth parameters and body chemical composition of a meat-type quail strain (Coturnix coturnix coturnix) and two laying quail strains (Coturnix coturnix japonica), designated yellow and red. The study used 1500 quail, not sexed, distributed in a

9. Establishment of a Pathogenicity Index for Mice to Pasteurella multocida Strains Isolated from Poultry and Swine
ABSTRACT Fowl cholera is a contagious disease that results from infection by the bacterium Pasteurella multocida. This microorganism is extensively distributed among animal species, but little is known regarding it’s pathogenesis and specificity to various hosts. Many studies using pathogenicity evaluation methods are subjective and difficult to quantify b

10. Monitoring structures with optical fibers: infiltration detection
ABSTRACT The use of sensors and optical fibers for monitoring structures is continuously growing. Strains, displacements, accelerations, temperatures are just a few of the monitoring possibilities. In the case of dam structures, concrete face rockfill dams constitute a type of structures where the monitoring of water infiltrations is of particular interest.

11. Estimation of growth parameters of body weight and body nutrient deposition in males and females of meat- and laying-type quail using the Gompertz model
ABSTRACT The objective of this study was to estimate the growth parameters of body weight and body nutrient deposition in males and females of one meat- (Coturnix coturnix coturnix) and two laying-type quail strains (Coturnix coturnix japonica), designated either yellow or red, using the Gompertz model. A total of 1350 quail from 1 to 42 days of age were use

12. Production Indicators and Levels of Corticosterone in Pullets Treated with Beak-Trimming Protocols
ABSTRACT The aim of this study was to compare the effects of beak trimming by hot blade or infrared radiation on production indicators and plasma levels of corticosterone in pullets. During the rearing phase, an entirely random delineation was used a 2 x 3 factorial design (two different techniques for beak trimming x 3 strains), a total of six treatments wi
