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 true digestibility coefficients and the values of true digestible amino acids of whole toasted soybean, micronized soybean and five soybean meals samples were determined. The forced feeding method was used with cecectomized adult cockerels. A total of 24 adult Leghorn cockerels averaging 2348 ± 165 g were used. Each feedstuff was fed to six cockerels, with the cockerel the experimental unit, in two replicates in the time. A total of 30 g of the tested feedstuff was forced fed […]

The chemical composition, the apparent metabolizable energy (AME) and apparent metabolizable energy corrected by nitrogen (AMEn) of six feed of vegetal origins were determined by the total excreta collection method. A total of 252 male broiler chicks of the lineage Ross with 21 days of age were distributed in a completely randomized experimental design, with seven treatments (one basal reference diet and six test diets), six replicates and six birds per experimental unit. The evaluated feeds were: corn (CO), high […]
