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.

The objectives of this study were to evaluate morphogenetic characteristics and tillering dynamics in Tanzania grass fertilized and non-fertilized with nitrogen, under intermittent grazing, in the spring and the summer. The main plots were composed of four nitrogen rates (0, 100, 200 and 300 kg/ha) and the subplots were growth seasons: spring (October, November and December) and summer (January, February and March). The experimental design was of randomized block with plots subdivided by time (seasons of the year) and four […]

The aim of this study was to evaluate morphogenetic characteristics and net herbage accumulation rate in Mombaçagrass pastures under three grazing intervals (28, 38 and 48 days) from October 1995 to September 1996. Trials were set in a split plot randomized block experimental design, with grazing intervals as main plots and periods as subplots. Leaf and stem elongation rates, leaf senescence rate, tiller density and pasture height were evaluated. Net herbage accumulation rate was estimated using tissue turnover data. Leaf […]
