Valadares Filho, Sebastião de Campos; Ferreira, Marcelo de Andrade; Muniz, Elaine Barbosa; Veras, Antônia Sherlânea ChavesA utilização de diferentes níveis de concentrado na ração (25; 37,5; 50; 62,5; e 75%) foi avaliada sobre as características da carcaça, o peso dos compartimentos do trato gastrintestinal, o peso dos órgãos internos e o conteúdo do trato gastrintestinal, de 24 bovinos mestiços Simental x Nelore, não-castrados, com 17 meses de idade e peso vivo médio de 354 kg. Os animais foram abatidos quando atingiram 500 kg de...
In vitro rumen fermentation kinetics of some co-products generated in the biodi...
Mizubuti, Ivone Yurika; Ribeiro, Edson Luis de Azambuja; Pereira, Elzania Sales; Pinto, Andrea Pereira; Franco, André Luiz CustódioFermentation kinetics rates of co-products generated in the supply chain of biodiesel were evaluated by in vitro gas production technique. Crambe meal, cottonseed meal, crambe cake, soybean cake and sunflower cake were evaluated. The soybean cake had higher rates of degradation of non-fiber carbohydrates (NFC), compared to other foods, resulting in higher volume of gas. Cottonseed meal and crambe meal had degra...
Importance of interrelation carbohydrate and protein in diets of ruminants
Pereira, Elzânia Sales; Arruda, Alex Martins Varela de; Miranda, Lídia Ferreira; Mizubuti, Ivone Yurika; Muniz, Elaine Barbosa; Pinto, Andréa PereiraThis literature review had as objective to relate the importance of the carbohydrate and protein synchronization in ruminant diets. The nutritional requirements systems to ruminant that give support to the diets formulations, require that the feeds commonly used in the feeding are fractional for best characterize them. Along the years there was considerable progress in the ruminant nutrition, but that progress,...
Eating behaviour of lactating cows fed with different preserved forages
Pereira, Elzânia Sales; Arruda, Alex Martins Varela de; Mizubuti, Ivone Yurika; Queiroz, Augusto César de; Muniz, Elaine Barbosa; Barreto, Júlio CésarThe objective of this study was to evaluate the effect of different forages preserved in silage form on eating behavior (feeding, rumination and leisure). Twelve Holstein lactating cows with a average 30 kg milk production were used. They were fed with three experimental diets composed by a combination of forages plus concentrate: (T1) 50 % of corn silage + 25 % of ryegrass silage + 25% of barley silage, (T2) 5...
