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 study was to analyze variability, linear and spatial correlations of forage dry mass yield (FDM) and dry matter percentage (DM%) of Brachiaria decumbens with the bulk density (BD), gravimetric (GM) and volumetric (VM) moisture, mechanical resistance to penetration (RP) and organic matter content (OM), at depths 1 (0-0.10 m) and 2 (0.10-0.20 m), in a Red Latosol (Oxisol), in order to select an indicator of soil physical quality and identify possible causes of pasture degradation. The […]

It were utilized four crossbreed, castrated, rumen cannuladed bovines, receiving dietary starea (containing 30% of urea) in the concentrate and corn silage, with the objective of quantify the liquid-associated bacteria and protozoa, solid-associated bacteria and related them with the ruminal pH. Three samples from ruminal content were harvested at 1 a.m., 2 a.m. and 30 min and 11 a.m. and 30 min after feeding. The microbial mass was quantified and qualified in the different fractions of solid-associated bacteria (SAB), liquid-associated […]
