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 experiment was to use n-alkane to estimate accurately and precisely the botanical composition of dietary forage in sheep fed different proportions of Arachis pintoi Koprov & Gregory cv. Amarillo and Brachiaria decumbens Stapf (0, 15, 30, 45 e 60% of Arachis pintoi). Twenty lambs were used in a completely randomized design with 10 days for diet adaptation and 5 days for fecal collection. Both fecal composites and hay samples were analyzed for n-alkane concentration. Dietary forage […]

The objective of this trial was to use n-alkanes to estimate dry matter intake (DMI) and DM digestibility in sheep. It was also of particular interest to compare two methodologies of fecal collection (total collection vs. grab samples) as well as to identify which n-alkanes best estimate DMI and DM digestibility. Twenty animals were assigned to a completely randomized design and were fed diets containing different proportions of forage peanut (Arachis pintoi Koprov & Gregory cv. Amarillo) and signalgrass hays […]
