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.

A Bayesian marker-free segregation analysis was applied for the estimation of variance components and to search for evidence of segregation genes affecting two carcass traits: intramuscular fat (IMF), %, and backfat thickness (BF), mm ; and one growth trait: body weight gain (LG) from 25 to 90 kg, approximately, g/day. In this study, 1,257 animals from the F2 design produced by breeding among pigs Meishan (male) and Dutch Large White and Landrace lines (female) were used. In animal breeding, finite […]

Genome scans can be used to identify chromosomal regions and eventually genes that control quantitative traits (QTL) of economic importance. In an experimental cross between Meishan (male) and Dutch Large White and Landrace lines (female), 298 F1 and 831 F2 animals were evaluated for intramuscular fat (GIM), % and growth trait: body weight gain (GP) from approximately 25 to 90 kg, g/day and 324 F1 and 805 F2 for backfat thickness, mm (ET). The animals of generations F1 and F2 […]
