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 carried out to evaluate factors related to the grazing efficiency of five Pennisetum sp. genotypes (CE 08 A.D., Venezuela, HV-241, Elephant B and Hexaplóide) during the dry period in the Forest Zone of Pernambuco. Genotypes were managed under rotational stocking (44 days of resting and four days of grazing period). It was used a split-plot arrangement in a complete randomized block design (genotypes represented the plots; grazing cycles, the subplots). Six replications were used to determine pre-grazing […]

It was evaluated the forage production from black oat (Avena strigosa Schreb) plus italian ryegrass (Lolium multiflorum Lam) mixture under grazing with beef heifers of Charolais breed and their crosses with Nellore submitted to following treatments: 0, 0.7, and 1.4% live weight/day of supplementation of rice bran plus citrus pulp (1:1). Daily dry matter accumulation rate (TA), botanical composition, forage losses and economic return of the different levels of supplementation were evaluated. The treatments with supplementation increased TA, however, the […]
