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 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 […]

This research was conducted to determine the minimum endogenous losses, the nutritional requirement of phosphorus (P) for maintenance, the biological availability of P from dicalcium phosphate and the variation of plasma P concentration in swine of 20 kg LW. The pigs were fed diets containing different levels of total phosphorus (.30, .40, .51, .65 and .73%). Twenty commercial crossbred barrows were maintained in metabolic cages for a seven-day period of adaptation and seven days of total collection of feces, urine […]
