The objective of this study was to evaluate the effect inclusion condensed tannins (CT) from black wattle (Acacia mearnsii) on feed intake, ruminal protozoa population, fermentation, and nutrient digestibility in Jersey steers. Five ruminally-cannulated steers were used a 5 × Latin square design, with five periods 20 days each (14 for diet adaptation six sample collection per period). Treatments composed dietary levels at 0, 5, 10, 15, g/kg dry matter. Intakes matter, organic ether extract,...
The objective of this study was to determine the optimal level dried brewers' grains (DBG) replace soybean meal in diets for lactating Holstein cows. Five cows, around 88±28 days milk, were distributed a 5 × Latin square design and fed containing different levels DBG (0, 25, 50, 75, 100%). forage:concentrate ratio diet 50:50. Feed intake, dry matter, nutrient digestibility, microbial synthesis, milk production composition, economic viability evaluated. There reduction matter intake and,...
RESUMO: Apesar do volume de leite produzido, a qualidade da matéria-prima é um dos maiores entraves ao desenvolvimento tecnológico e à consolidação indústria laticínios no Brasil. Dentre os entraves, toma destaque contagem células somáticas leite, que o indicador mais usado em programas controle prevenção mastite todo mundo. Com objetivo identificar características manejo ordenha quantificar fatores risco elevam subclínica seus principais agentes causadores, realizou-se coleta dados in loco...
The objective of the study was to evaluate replacement Tifton 85 hay (TH) for silage (TS) in diets lactating cows. Five Holstein cows middle lactation were allocated a 5 × Latin square design and each experimental period lasted 18 days (12 adaptation six collection). Treatments consisted 0, 25, 50, 75, 100% TH TS. intake digestion nutrients, microbial protein synthesis, milk yield composition, economic viability evaluated. intakes dry matter, organic ether extract had positive linear effect...
