The Revista Brasileira de Zootecnia (RBZ) is a publication dedicated to the broad field of Animal Science. We publish high-quality, original scientific research that spans across diverse areas within the discipline. The scope of RBZ encompasses a wide range of topics, including aquaculture, biometeorology and animal welfare, forage crops and grasslands, animal and forage plants breeding and genetics, animal reproduction, ruminant and non-ruminant nutrition, meat science and muscle biology, precision livestock, and animal production systems and agribusiness.

The experiment was conducted to evaluate the dry matter (DM), crude protein (CP) and neutral detergent fiber (NDF) degradation kinetics and different models to estimate the passage rate in steers fed diets with 15.0% of broiler litter associated to two levels of a supplement based on bovine lyophilized ruminal microbiota (0 and 10 g/animal•day). Four steers with ruminal and abomasal fistulae were allotted to a completely randomized experiment. The passage rate was determined using chromium complexed to the cellular wall […]

The objective of this work was to evaluate the in situ disappearance of canola meal treated with water (control), in autoclave at 127oC for 30 min (CC), with 15% of Acacia mearnsii tannin (CT) and tannin followed by autoclaving (CTC). The effect of these treatments on in situ disappearance of dry matter (DM) and crude protein (CP) was evaluated by the nylon bag technique, using two rumen fistulated Holstein cows. The estimates of effective degradation of DM for control, CC, […]
