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 during two years for evaluation of the soil/pasture system response to phosphorus fertilizers with different solubilization rates (ordinary superphosphate, triple superphosphate, and termalphosphate), with and without liming. The various phosphorus sources did not affect forage yield when fertilization was made during two years. Association of fertilizers may be advantageous since termalphosphate promoted the best forage yield when phosphorus fertilization was suppressed in the second year while fertilization with superphosphates resulted in best forage yield in the […]

The experiment was carried out to study the effects of fiber levels (38.7 and 57.2% NDF), composed of elephantgrass silage and chopped sugarcane and two protein sources, a high (soybean meal) and low (blood meal and corn glúten meal) ruminal degradable protein, on the ammonia nitrogen concentration (N-NH3) and on the ruminal pH of steers. Four rumen fistulated Brow-Swiss steers, with 316 kg of average initial weight, were randomly allotted to a 4 x 4 Latin square design. The steers […]
