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.

It was evaluated the effect of nitrogen fertilization (100 and 200 kg/ha of N as urea) on the components of forage production of an improved native pasture with 3.12 ha (paddocks – 0.52 ha). Control areas without application of N were used, using a complete block design with two replications. Paddocks were grazed by lambs in a continuous stocking and variable stocking rate to keep forage allowance of 16% LW. In spring of 2004, pasture was uniformly fertilized with 250 […]
Keywords: continuous stocking; forage allowance; herbage height; herbage mass; volumetric density

To evaluate the pattern of defoliation in a Mombaça (Panicum maximum) grass pasture, experimental paddocks were grazed by Holstein heifers to maintain canopy height of: 60, 80, 100, 120 and 140 cm height. The experimental design was completely randomized, with two replications. The assessed sward structures were: canopy height; herbage and leaf lamina mass; canopy, sheath plus stems and leaves bulk density; tiller density and number and length of fully-expanded and emerging leaves. Linear decrease in plant defoliation probability (Y= […]
Keywords: diet selection; leaf size; crossbreed cows; selectivity; volumetric density
