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.

This experiment was carried out to determine the values of the real digestibility coefficients of amino acids by using the method of “forced feed” with cecectomized roosters. The studied food were the following: rice bran, whole rice meal, corn, sorghum, wheat bran, soybean meal, cotton meal 28%, cotton meal 38%, yeast sugar cane 43% and yeast sugar cane 40%. The mean values of real digestibility coefficients of essential and non-essential amino acids were, in percentage, the following: for rice bran, […]

Four assays were carried out to determine the apparent metabolizable energy (AME) and nitrogen corrected apparent metabolizable energy (AMEn) of ten feedstuffs of vegetable origin for poultry at different ages. The chemical composition of the ten feedstuffs was also determined: 45% soybean meal, 48% soybean meal, extruded full-fat soybean, deactivated full-fat soybean, micronized full-fat soybean, deactivated soybean meal, soybean protein concentrate, corn gluten meal 21%, corn germ and broken rice. The method of total excreta collection was used and a […]
