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 experiment was to determine the digestible lysine requirement for male broilers in the period from 22 to 42 days. Four hundred and sixty male broilers Hubbard, with an initial average weight of 631 g, were allotted in a randomized block experimental design with five treatments, six replicates and 15 birds by experimental unit. The treatments corresponded to five L-lysine levels supplemented to a basal diet with 19,64% of crude protein and 3100 kcal of ME/Kg resulting […]

The objective of this experiment was to determine the digestible lysine requirement for male broilers from 1 to 21 days. Six hundred male broiler chicks, Hubbard, with an average weight of 48 g were allotted to randomized blocks experimental design with five treatments, six replicates and 20 chicks per experimental unit. The treatments corresponded to the basal diet, with 20.85% of crude protein and 3000 kcal of ME/kg, attending the requirements of protein, energy, calcium, phosphorus and amino acids, except […]
