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.

Evaluation of Nutritive Characteristics of the Grasses Brachiaria brizantha cv. Marandu, Setaria sphacelata cv. Kazungula and Panicum maximum cv. Tanzânia-1 in the Seasons of the Year
A field plot experiment was conducted, in a split plot design with 12 replications to compare the percentages of crude protein (CP), neutral detergent fibber (NDF) and in vitro dry matter disappearance (IVDMD), of the whole plant and its leaf blades and stems of the grasses Marandu (Brachiaria brizantha Stapf. cv. Marandu), Setaria (Setaria sphacelata cv. Kazungula ) and Tanzania (Panicum maximum Jacq. cv. Tanzania-1) in cuts taken at 35 days of growth in the spring (11/21 to 12/25/97), summer (12/29/97 to 02/02/98), fall (04/13 to 05/18/98) and winter (05/28/98 to 07/01/98). The plots were the grasses and the split-plots were the year seasons. Marandu and Tanzania did not differ for the CP and IVDMD percentages, but Tanzania NDF was higher than the ones of the other two grasses. Setaria showed high levels of CP but the least IVDMD. The best nutritive value, considering higher CP and IVDMD and lower NDF percentages, was observed during the autumn, for the three grasses.
