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.

Abstract We investigated whether a panel of molecular markers previously associated with temperament has an effect on live growth traits. Phenotypic data from 412 Charolais cows categorized according to their age in adult and young cows were used to determine Pearson’s correlations between birth (BW), weaning (WW), and yearling live (YW) weight and temperament traits (measured as exit velocity [EV] and temperament score [TS]). For association analysis, selective genotyping of a group of 80 cows identified as the most docile […]

ABSTRACT In this study, we aimed to provide a wet laboratory validation for a set of single nucleotide polymorphisms (SNP), which had been identified as candidate functional variants in silico. Genotyping for candidate SNP was performed in Brahman and Tropical Composite cattle. After quality control, 29 SNP were first investigated individually for their association with female reproductive traits and then used as a panel for genomic predictions. The reproductive traits studied were age at first corpus luteum (AGECL; days), post-partum […]

Records of the weights at birth, weaning and monthly from 8 to 19 months of age from three genetic groups: ½Canchim-Nellore (CN), ½Angus-Nellore (AN) e ½Simmental-Nellore (SN), born in 1998 and 1999 in Southeast Brazil, were used to fit a Logistic nonlinear model that included the fixed effects of the contemporary group and genotype of the genes kappa-casein-HinfI (CSN3): AA and AB, growth hormone-AluI (GH): LL and LV, and b-lactoglobulin-HaeIII (LGB): AA, AB and BB, to examine the effect of […]
