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 evaluate the use of the dietary cation-anion balance (DCAB) on the calcium metabolism in male Nellore steers with a mean age of 10 months. Three experimental diets were tested: a cationic diet, a diet consisting of Tifton hay only, and an anionic diet with +15.2, +23.9 and −10.0 mEq/100 g DM of DCAB values in the diet. The anionic diet was calculated as the addition of salts of ammonium chloride and magnesium sulfate. […]

The experiment was designed to simulate the mathematical models that relate to the phophorus (P) flow, considering the hypotheses that the endogenous phosphorus from digestive tract was absorbed in the same proportion of the dietary phosphorus and that the input and output flow of this mineral in the compartments was constant. The variables absorption, retention, endogenous P that returns to the gastrointestinal tract (GIT), dietary absorbed P, accretion, reabsorption and balance of P in bone and in soft tissues and […]
