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 experiment was accomplished in a greenhouse from May to August of 2005, with the objective of to evaluate the effect of phosphorus and nitrogen fertilization on morphogenetic and structural characteristicas of Tanzania grass. The morphogenetic evaluations included leaf appearance, leaf elongation rate, and stem elongation rate. The structural evaluations measurements were: number of leaves, number of green leaves, number of tillers per plant, and final leaf length. It was used a complete randomized experimental design in 4 x 2 […]

This experiment was carried out to evaluate the influence of different fertilization and cutting intensity combinations on morphogenic and productive characteristics of Panicum maximum Jaccq., cv. Tanzania in pots. Leaf appearance rate (LAR) and phyllochron were not influenced by cutting intensities. Plants fertilized with N, however, produced greater LAR and phyllochron, with 0.21, 0.20, and 0.19 leaf/day and 4.67, 5.03, and 5.43 day/leaf for N and K (NK), N and P (NP), and N, P and K (NPK) combinations, respectively.

An experiment was carried out during two years on Cerrado soil with the objective of evaluating the response of degraded Brachiaria brizantha cv. Marandu pastures to different N and S fertilization doses. Seven treatments, six with different N and S combinations and a control (degraded pasture), were compared in a randomized complete blocks design. The combinations were: 70 kg ha-1 N without sulphur, 140 kg ha-1 N without sulphur, 210 kg ha-1 N without sulphur, 70 kg ha-1 N and […]
