Fontes energéticas associadas ao farelo de girassol ou à ureia em dietas para novilhos
(Archivos de Zootecnia, 2012-09-01) [Artigo]
The objective of this study was to evaluate the performance and carcass traits of steers fed corn or citrus pulp associated with sunflower meal or urea. Diets were composed of two energy sources (corn grain and citrus pulp) ...
Estudio de efectos ambientales y genéticos que influyen en la producción de leche y duración de lactación en bovinos de raza guzerat
(Livestock Research for Rural Development, 2011-07-01) [Artigo]
Objective of present work was study a influence of environmental and genetic effects over characteristics of milk total production (PL) and lactation duration (DL), from 2572 lactations of 477 Guzerat cows, collected since ...
Glicerina bruta na dieta de bovinos de corte confinados: Efeito sobre o hemograma
(Brazilian Journal of Veterinary Research and Animal Science, 2012-12-01) [Artigo]
The aim of this study was to evaluate the hemogram in cattle fed crude glycerin. 30 Nellore steers, were used for blood sampling, which were done each 28 days. The animals were confined for 103 days and were fed with five ...
Variance heterogeneity for milk yield in Brazilian and Colombian Holstein herds
(Livestock Research for Rural Development, 2004-04-01) [Artigo]
Heterogeneity of variances for milk yield (MY) was determined for Brazilian and Colombian herds. The herds were grouped as high or low variability within each country, using as criterion the phenotypic standard deviation ...
Phenotypic plasticity of composite beef cattle performance using reaction norms model with unknown covariate
(Animal, 2013-02-01) [Artigo]
The objective of the present study was to determine the presence of genotype by environment interaction (G × E) and to characterize the phenotypic plasticity of birth weight (BW), weaning weight (WW), postweaning weight ...
Morphologic and Cytogenetic Description of the Small Red Brocket (Mazama bororo Duarte, 1996) in Brazil
(Mammalia, 2003-12-01) [Artigo]
We evaluated morphological and cytogenetic data for three animals similar to the species of deer previously described as the Small Red Brocket (Mazama bororo Duarte, 1996). We compared these animals with five M. americana, ...

Were used 64 weaned pigs, distributed in eight treatments: ration with skim milk (SM), three rations with crescent levels of swine plasma (SP), three rations with whole egg (WE) and a ration with high inclusion of soybean ...
Estimates of direct and maternal genetic effects for weights from birth to 600 days of age in Nelore cattle
(Journal of Animal Breeding and Genetics, 2001-12-01) [Artigo]
Estimates of direct and maternal variance and heritability for weights at each week (up to 280 days of age) and month of age (up to 600 days of age) in Zebu cattle are presented. More than one million records on 200 000 ...
Multi-trait and random regression mature weight heritability and breeding value estimates in Nelore cattle
(South African Journal of Animal Sciences, 2009-12-01) [Artigo]
Mature weight breeding values were estimated using a multi-trait animal model (MM) and a random regression animal model (RRM). Data consisted of 82 064 weight records from 8 145 animals, recorded from birth to eight years ...
Análise espermática de perdizes (Rhynchotus rufescens) criadas em cativeiro e suplementadas com selênio
(Brazilian Journal of Veterinary Research and Animal Science, 2011-12-01) [Artigo]
Due to the commercial importance of the red-winged tinamou (Rhynchotus rufescens), for the past few years, the employment of reproductive biotechnologies has been attempted. Thirty animals were randomly assigned into two ...
