Potencialidades da utilização de taninos na conservação de forragens e nutrição de ruminantes-revisão
(Archives of Veterinary Science, 2007-11-21) [Artigo]
This review present a discussion abouth the tannins. The tannins are compounds that have the ability to bind other macromolecules, reducing their availability to animal metabolism. This characteristic can be benefic or ...
Relações materno-filiais e sua influência no peso pré-desmama de animais Nelore da Bahia
(Archivos de Zootecnia, 2009-10-27) [Artigo]
The aim of this study was to investigate the maternal-offspring relationships in the bovine breeds Nellore PO (Pure Breed) and Nellore CL (Cara Limpa) in Bahia State. The genetic composition of breeds did not affect LP ...
Desempenho de bovinos em pastejo submetidos a duas frequências de suplementação no período da seca
(Acta Scientiarum: Animal Sciences, 2009-12-01) [Artigo]
This work was carried out to evaluate different frequencies of supplementation during the dry season. Forty-eight Nellore steers with 320 kg of initial live weight were fed with Brachiaria brizantha cv. Marandu pasture on ...
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 ...
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, ...
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 ...
