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.

Two experiments were conducted to evaluate the effects of digestible energy (DE) levels on performance and carcass gain composition. Fifty crossbred gilts and 50 crossbred barrows, from 30 to 60 kg, maintained in a thermoneutral environment, were used. The experimental design was a randomized blocks with five treatments (3100, 3250, 3400, 3550, and 3700 kcal de DE/kg of diet), five replicates and two animals per experimental unit. In the experiment with gilts the DE level did not influence daily weight […]
