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 purpose of this study was to determine the N-corrected apparent metabolizable energy (EMAn) of alternative protein ingredients, for newly hatched chicks, and to evaluate the effects of the utilization of these ingredients in the first week broiler feed, on the performance and gastrointestinal tract (TGI) development. In the metabolism trial, 288 male chicks from 4 to 7 days were allotted to a completely randomized design with six treatments (a reference diet and five diets with inclusion of the test […]

This work was conducted to determine the N-corrected apparent metabolizable energy (EMAn) of different carbohydrate sources for broilers from 1 to 7 days, and to evaluate the utilization of these ingredients in the diet of newly hatched broilers based and on live performance and on the gastrointestinal tract (TGI) development. Total excreta collection method was used in trial one, with 220 male chicks from 4 to 7 days, allocated to batteries in a completely randomized design with five treatments (a […]
