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.

Production of better quality forage can be achieved by changing grazing method, from continuous grazing by rotational grazing, associated with fertilization practices, especially nitrogen fertilization. It was evaluated during the rainy seasons of 2002/03 and 2003/04 the effect of nitrogen doses (0, 100, 200 and 300 kg ha-1) on dry matter yield and on chemical composition (crude protein, ADF, NDF, hemicellulose, cellulose and lignin) of a Urochroa decumbens cv. Basilisk pasture, managed under rotational grazing. In addition, it was evaluated […]

The objective of this experiment was to evaluate the effect of utilization of soybean meal or corn gluten meal on in situ ruminal degradabilities of diets, based on coastcross hay, corn and one of the nitrogen sources, fed to bulls, with average weight of 650 kg. Corn gluten meal was considered as a nitrogen source of low degradability and the SBM as intermediate ruminal degradability. They presented nitrogen potencial degradability of 39.7 and 90.3% and effective degradability of 35.7 and […]
