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 study was conducted to evaluate the biological flow of P in pigs fed diets based on corn, soybean meal, defatted rice bran (DRB) and soybean oil, with increasing phytase levels (253, 759, 1265 and 1748 PU/kg of diet), using mathematics models. The model was deterministic and compartimental, in which the gastrintestinal tract (GIT) (C1), the plasma C2, the bones (C3) and the soft tissues (liver, heart, kidney and muscle) (C4) represented the compartments. Metabolism data and kinetics of P […]
