Abstract

Heritability estimates of growth traits are essential information in animal breeding programmes. 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 shown that for all traits, Nelore cattle, the majority of cattle in Brazil, had greater pooled heritability estimates than the other breeds. Restricted maximum likelihood and DerSimonian and Laird methods were used to estimate the variance between studies, where the first method showed higher variances.
