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.

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= […]

This trial was carried out to evaluate the morphological characteristics of three Elephant grass clones (Cameroon, Roxo de Botucatu and Mott) and an Elephant grass with pearl millet hybrid (HV-241) submitted to two humidity regimes (with and without water stress). A randomized block design with split plots and three replicates was used. In the main plot, the effect of the humidity regimes was studied, and in the split plot, the different clones. Plants submitted to water stress showed lower height, […]
