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 objective of this trial was to evaluate the effect of feed restriction during a grazing period of 104 days (phase I) on intake, feed conversion, and digesta load as well as body weight (BW) change and weights of carcass and non-carcass components during a feedlot period (phase II) in crossbred steers. Thirty nine crossbred Holstein-Gyr steers averaging 19.3±5.1 months of age and 202.0±49.1 kg of BW at the beginning of the study were used. Animals were assigned to one […]

The influence of the level of forage intake on the degradability of particles of elephant grass in the sections of gastrointestinal tract (GIT) of bovines and on some traits of ruminal kinetics was studied. A completely randomized split plot design was used, with twelve treatments in the main plots (a 2×6 factorial, comprising two levels of feeding: restricted – NA1 and unrestricted – NA2, and six slaughter times) and the five sections GIT in the split plots. Thirty-six steers maintained […]
