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 conducted with the objective of predicting the dry matter (DM) digestibility of rations for growing rabbits, by means of equations based on the concept of ideal nutritive entity. One hundred 42-day-old rabbits from the Botucatu Genetic Group were used. Sixteen rations were tested, containing roughage (paper, corn cobs, sugarcane bagasse or pine shavings), plus corn, soybean meal, soybean oil, kaolin and common salt. Roughages were included at four levels, to obtain 22, 28, 34 or 40% neutral […]

The objective of this work was to evaluate the equations adopted by the NRC and Detmann to estimate the energy content of agricultural and agroindustrial byproducts. It was evaluated byproducts of pineapple, cocoa, palm oil, beans, sunflower, guava, cassava bark, cassava stem, raw cassava, papaya, mango, passion fruit, turnip and corn gluten meal. All animals received corn silage and the mixture urea/ammonium sulfate (9:1) so rations with the two levels of each byproduct remained isonitrogenous. Among the models for digestible […]

Twelve lactating dairy cows (Holstein and crossbred Holstein x Zebu) were blocked by days in milk and randomly assigned to three replicate 4 x 4 Latin squares to compare two schedules of total fecal collection (two versus six days) and the reliability of two internal markers [indigestible neutral detergent fiber (INDF) or indigestible acid detergent fiber (IADF)] to estimate fecal DM excretion (FDME), apparent total tract digestibility of nutrients, and the total digestible nutrients (TDN) content of the diets. The […]
