2. Do live or inactive yeasts improve cattle ruminal environment?
ABSTRACT This research was conducted to investigate the effect of live and inactive sugarcane yeast on beef cattle voluntary intake, apparent digestibility of nutrients, ruminal pH, volatile fatty acids (VFA) concentrations, and ruminal ammonia. Five rumen-cannulated Nellore heifers were distributed in a 5×5 Latin square design, with five experimental perio

3. Características da Carcaça de Novilhos F1 Guzerá + Nelore e F2 Guzerá + Limousin + Nelore. / Carcass Characteristics of F1 Guzerá + Nellore and F2 Guzerá + Limousin + Nellore Steers.
Carcass characteristics of Guzerá + Nellore (F1) and Guzerá + Limousin + Nellore (F2) were evaluated. Each experimental group was constituted by twelve animals. The bovines presented respective average weights to F1 and F2 of 477,50 18,54 and 468,89 21,03 kg at the beginning of experimental period and 526,83 18,77 kg and 516,08 20,03 kg in the slaughter oc

4. Behavioral patterns of Angus, Caracu and Nelore beef cattle under grazing conditions with availability of shade and water for immersion / Aspectos comportamentais de bovinos das raças Angus, Caracu e Nelore a pasto frente à disponibilidade de recursos de sombra e água para imersão
Cattle under grazing conditions in tropical areas seek for shade as a thermal comfort resource often during the hottest periods of the day. The objective of this study was to evaluate and understand how cattle of different origins (Caracu - adapted taurus, Nellore - zebu and Red Angus - european taurus) use the thermal comfort resources, quantifying the freq

6. Consumo e digestibilidade do feno de Brachiariia brizantha cv. MG4 por bovinos suplementados com diferentes niveis de uréia / Intake and digestibility of Brachiaria brizantha cv. MG4 hay for bovine supplemented with different levels of urea
The intake and apparent digestibility of dry matter (DM), organic matter (OM), neutral detergent fiber (NDF), crude protein (CP), non fiber carbohydrate (NCF), eter extract (EE)) and total digestible nutrients (TND) of the low quality Brachiaria brizantha cv. MG4 hay were evaluated on presence of increasing urea levels. Where used five Nellore steers, male,

7. Intake, partial and tract total digestibility, microbial protein synthesis and metabolizable protein requirements for maintenance of Nellore bovines / Consumo, digestibilidades total e parcial, produção microbiana e exigências de proteína para mantença de bovinos Nelore
Two trials were conducted from May to November 2004. Each experimental period lasted 15 days nine for diet adaptation and six for collections. In the first experiment, twelve Nellore of three sexual categories (four heifers, four bulls and four steers) averaging 15 months of age and body weight of 235, 249, and 239 kg, respectively, were assigned to a comple

9. Exigências de proteína e energia líquidas para o ganho de peso de tourinhos das raças Nelore e Brangus alimentados com dietas com diferentes proporções de concentrado. / Protein and energy requirements for weight gain of Nellore and Brangus bulls fed with different concentrate levels.
The determination of energy and protein requirements for maintenance and growth of beef cattle is very important for an efficient animal production. Nellore and crossed breeds like Brangus are very used in Brazil, but the main source of information about nutritional requirements is the NRC, whose data was obtained with different breeds and environments. The
