1. Evaluation of Bayesian models for analysis of crude protein requirement for pigs of Brazilian Piau breed
ABSTRACT: We evaluated the inclusion of information on genetic relationship into the analysis of crude protein requirement in diets for pigs of Brazilian Piau breed, using Bayesian inference. The animals were assigned to treatments in a completely randomized design in factorial scheme 4 × 2 (crude protein levels × sex) with 12 repetitions per treatment. Th

3. Effects of Diets with Graded Levels of Canola Meal on the Growth Performance, Meat Qualities, Relative Organ Weights, and Blood Characteristics of Broiler Chickens
ABSTRACT This experiment was conducted to evaluate the dietary supplementation of canola meal (CM) on the growth performance, carcass characteristics, antibody titers against Newcastle disease virus and Infectious bronchitis virus, and blood profiles of broiler chickens. In total 600 day-old feather-sexed Ross male broiler chicks were randomly assigned into

4. Performance, intestinal histomorphometry, and blood parameters of post-weaning piglets receiving different levels of soy protein concentrate in the diet
ABSTRACT Seventy-two barrows were used to evaluate the effects of the use of soy protein concentrate (SPC) in diets of post-weaning piglets on their performance, intestinal histomorphometry, and blood parameters. Piglets were weaned at 21 days of age and distributed in a randomized-block experimental design with four treatments (0, 3, 6, and 9% SPC), six rep

5. Live Performance, Carcass Yield, and Welfare of Broilers of Different Genetic Strains Reared at Different Housing Densities
Abstract This study evaluated the performance, carcass yield and quality, and physiological stress indicators of broilers of three genetic strains reared at three housing densities for 29 days. A total of 828 day-old male chicks, with average initial weight of 40.0± 2.0g were used. Three genetic strains (Cobb 500, Ross 808, and Ross 508, with 276 birds each

6. Effect of plasma and/or yeast extract on performance and intestinal morphology of piglets from 7 to 63 days of age
The objective of this study was to evaluate the effect of diets supplemented with plasma and/or yeast extract on performance (daily weight gain [DWG], daily feed intake [DFI] and feed conversion [FC]) and intestinal morphology of piglets from 7 to 63 days of age. A total of 288 piglets aged 7 days and weighing 2.57±0.05 kg were studied. A randomized block d

7. Sources of organic trace minerals in diets for weaned piglets
One hundred and twenty six piglets from a commercial genetic strain weaned at 21 days of age (6.11±0.42 kg) were used to evaluate the effects of supplementation levels of organic sources of trace minerals in the diets of weaned piglets on performance, occurrence of diarrhea, excretion of copper and zinc in the feces, and hematological parameters. A complete

8. Post-weaning weight gain and pregnancy rate of beef heifers bred at 18 months of age: a meta-analysis approach
The objective of this study was to evaluate, using meta-analysis, the main factors related to post-weaning body weight and weight gain that affect pregnancy rate of heifers bred at 18 months of age. Data of 1398 beef heifers from six experiments were analyzed as a set. Information related to methodology and results of each experiment were codified in Microso

11. Influência do peso dos leitões na uniformização no desempenho de primíparas suínas e suas leitegadas. / Influence of piglets weight at crossfostering on the performance of primiparous sows and their litters
The objective of this study was to evaluate the effect of crossfostering piglets with different birth weight on feed intake, body reserve losses and reproductive performance of primiparous sows and on performance of their litters until weaning. Primiparous sows were allocated in three groups: group A (n= 31) ¿ litters with 14 Light piglets (1.0-1.2 kg); gro

12. Avaliação de parametros clínicos, hematológicos e viabilidade econômica do uso do florfenicol na metafilaxia das afecções respiratórias inespecíficas de bovinos confinados no estado de Goiás / Evaluation of parameters clinical, hematological and economic feasibility of the use of florfenicol metaphilaxys nonspecific respiratory infections feedlot on Goias state
Producing more in less physical space and in less time, increasing the profitability and reducing sanitary and economical risks are some of the challenges of the Brazilian livestock that the intensive breeding aims to supplant. A considerable increase in the number of confining unities as well as in feedlot cattle is already observed, thus, the attention to
