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.

This work was carried-out to study the effect of substitution levels of corn (COR) by cassava by-product flour (CPF) (25, 50, 75 and 100%) in the ration for sheep on voluntary intake, nutrients apparent digestibility and nitrogen (NB) and energy (EB) balance, pH and ammonia concentration (N-NH3) in ruminal liquid. Four male, castrated sheep, without defined race, with medium weight of 41.4 AW, in trial of digestibility were used, using the method of total collect feces and urine. The animals […]

The objective of this paper was evaluate ammonia concentration, pH of ruminal liquid and microbial synthesis efficiency in diets with different energetic sources: corn (CO), corn/cassava hulls (CC), cassava root (CR) and cassava by-product flour (CB). Four Holstein steers (270 kg) were used, in a 4 X 4 Latin Square design. The marker utilized for determination of duodenal and fecal flow was the acid insoluble ash. There was not effect in the ruminal pH of the experimental diets, however smaller […]
