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 at farm Pedrões of the F.C. Agropecuária, located in Uberaba-MG to evaluate the quality of Brachiaria decumbens hays harvested after seed ripening. The hays were submitted to the following treatments: control, anhydrous ammonia (3.0% NH3 in the DM), and urea (5.0% in the DM). The chemical composition, digestibility hays and the performance of steers were evaluated using a complete randomized block design with three treatments and six replications. The ammoniation either with NH3 or urea increased […]

The research was conducted to evaluate two sources of ammonia (anhydrous ammonia-NH3 or urea) to preserve alfalfa (Medicago sativa L.) hay stored with high moisture. The following treatments were studied: A – Control: untreated hay (12 to 15% moisture); B – hay (24 to 27% moisture) treated with NH3 (1.0% of DM); C – hay (24 to 27% moisture) treated with urea (0.9% DM); D – hay (24 to 27% moisture) treated with urea (1.8% DM); E – hay (34 […]

The experiment was conducted to evaluate the changes on the chemical composition and the in vitro dry matter digestibility (IVDMD) of the Brachiaria decumbens Stapf, jaraguá (Hyparrhenia rufa Ness Stapf) hays, untreated, treated with urea (5.4% DM), urea (UL-5.4% DM) and lab lab (Lablab purpureus L. Sweet, cv. Highworth-3.0% DM); and anhydrous ammonia (NH3 3.0% DM). The chemical treatment increased the pH and the in vitro digestibility of the hays Ammoniation did not affect ADF and cellulose contents. The NDF, […]
