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 ...
Comparação de sistemas de avaliação de dietas para bovinos no modelo de produção intensiva de carne. Confinamento de tourinhos jovens
(Revista Brasileira de Zootecnia, 2002-01-01) [Artigo]
Thirty 3/4 Canchim + 1/4 Nelore young bulls with 417 kg of body weight and 15 months of age, were confined during 84 days. The animals were fed with diets composed with corn silage, corn grain, cottonseed meal, soybean ...
Métodos de coleta de fezes e determinação dos coeficientes de digestibilidade da fração protéica e da energia de alimentos para o pacu, Piaractus mesopotamicus (Holmberg, 1887)
(Revista Brasileira de Zootecnia, 2004-09-01) [Artigo]
To improve the pacu (Piaracatus mesopotamicus) feeding in the growth phase, it's necessary to know the digestibility of the ingredients used in his diets. Initially, four fecal collection methods were analyzed (dissection, ...
Rendimento dos não-componentes da carcaça de cordeiros de diferentes genótipos
(Archivos de Zootecnia, 2008-03-01) [Artigo]
Non-carcass components percentages of lambs terminated in confinement, fed with diet containing 40:60 forage:concentrate ratio were influenced by lambs' breed (Morada Nova and 1/2 Somális Brasileira 1/2 Morada Nova), except ...
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, ...
Plasma suíno e ovo inteiro em rações de leitões sobre desempenho na fase inicial e efeito residual até a terminação
(Brazilian Journal of Veterinary Research and Animal Science, 2011-05-31) [Artigo]
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 ...
Diferentes procedimentos na determinação de indicadores internos para estimativa de produção fecal e fluxo duodenal de matéria seca em bovinos
(Acta Scientiarum: Animal Sciences, 2010-08-20) [Artigo]
Times of in situ incubation (144 and 288h) for determination of internal markers IADF and INDF and the effects of differents procedures (wash or not the nylon bag every 72h incubation) was evaluated in samples of diet, ...
Comparações entre equações de predição de consumo de capim-elefante cortado para vacas lactantes
(Archivos de Zootecnia, 2008-07-25) [Artigo]
This work aimed to compare intake prediction equations with values obtained by direct methods using chopped elephant-grass offered to crossbreed lactating cows with rumen canulas. The experimental design was a 3 x 3 Latin ...
