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 objective of this study was to determine the coefficients of apparent and true digestibility of protein and amino acids of five feedstuffs (corn, wheat bran, soybean meal, corn gluten meal and fish meal) in 900 sex-reversed Nile tilapia (Oreochromis niloticus) of the Thai strain during the growth phase, with an initial weight of 315±8.45 g. A total of 750 fish were distributed according to a randomized block design (repetitions in time) into five treatments with six replicates of 25 […]

The objective of the present study was to propose the use of protein free diet (PFD) associated with synthetic amino acids (AA) as method to determine the amino acid and protein endogenous loss in broiler chicks, as the normal endogenous flux is underestimated in PFD use. Eighty-four Ross 308 male chickens were used, aged from 17 to 22 days in a randomized complete design, totaling two treatments with six replications, with seven birds per experimental unit. The endogenous amino acid […]
