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.

Heritability estimates of growth traits are essential informations in animal breeding programs. In this paper, 869 heritability estimates of birth weight, weaning weight, weight at 365 days old and weight at 550 days old, of 186 reports were compiled. The estimates were divided in groups using the Ward method of cluster analysis, and pooled by meta-analysis. It was observed, for all traits, that groups from Nelore breed, majority in Brasil, showed greater pooled heritability estimates than the other groups. The methods, restricted maximum likelihood and DerSimonian and Laird, were used to estimate the variance between studies, where the first method showed higher variances.
