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.

This experiment was carried out with the objectives of determining repeatability coefficients, the number of harvests necessary to increase accuracy and the genotypic stability of yield characteristics in Brachiaria brizantha cultivars in the northeast region of Brazil in the period from July 2009 to March 2011. The experimental design used was completely randomized with three treatments (Brachiaria brizantha var. Marandu, Xaraés and Piatã) and three replications. Each plot was harvested seven times: five in the rainy season and two in […]

The experiment was carried out with the objectives to evaluate the use of morphologic descriptor in the characterization and selection of dwarf elephant grass genotypes, and to evaluate the heritability of the evaluated traits. Nine dwarf elephant grass clones were used (Taiwan A.146 – 2.14, Taiwan A.146 – 2.27, Taiwan A.146 – 2.37, Taiwan A.146 – 2.114, Merker México – 6.2, Merker México – 6.5, Merker México – 6.31, cv. Mott, and CNPGL92F198.7) was allotted to a randomized complete block […]

The genus Brachiaria encompasses about one hundred species and the correct classification of the accessions involved in the breeding programs is of great interest for the genetic improvement of this forage species. Three hundred and one accessions of six different Brachiaria species were analyzed, in which vegetative, reproductive and pubescence characteristics were evaluated. Anderson’s discriminant analyses were conducted for each one of the three groups of morphological traits and discriminant functions were established for the six species. Rates of correct […]
