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.

One experiment was conducted to evaluate the utilization of rice by-products in diets based on crude and ideal protein concepts for broilers from 1 to 42 days of age. Seven hundred and twenty male chicks, one day old, Hybro strain, were distributed in a completely randomized design in a 3 × 2 factorial arrangment, three diets (without by-product, whole rice meal and broken rice) and two ration formulation concepts (crude and ideal protein), totalizing six treatments and four replications of 30 birds. Weight gain, feed intake and feed:gain ratio were evaluated at 21 and 42 days, and carcass characteristics at 42 days of age. In conclusion, birds fed diets formulated by the traditional concept (based on crude protein) showed better feed:gain ratio and lower deposition rate of abdominal fat.
