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.

In this study, it was aimed to evaluate the economic responses of finishing Nellore steers to supplementation of Brachiaria brizantha pastures in southwestern Bahia. The experiment was developed from August to November 2006 in a 52-ha area divided in eight pickets of approximately 6.5 hectares each. It was tested four levels of concentrate supplementation (control, 0.3, 0.6 and 0.9% of the body weight of animal) compared to supplementation with mineral salt. Supplementation levels raised the amount of meat produced per hectare. The curve of revenue growth is less sharp than the cost growth curve, resulting in a flattening of profit according to levels of the studied supplementation. The best biological results obtained from high levels of supplements are not economically sustainable because of the increase in the production cost, however, supplementation levels lower than 0.3% of body weight in the finishing phase are feasible and they are potentially economical.
