A meta-analysis was conducted to summarize published heritability estimates of growth traits of zebu beef cattle in 186 reports. The factors affecting weighed heritability estimates were analysed by the least square means method for a model including fixed effects. Breed and estimation method were the significant factors in the four growth traits (birth weight, weaning weight, weight at 365 days and weight at 550 days). Estimation method is always recommended to summarize these estimates. The pooled heritability estimates for birth weight, weaning weight, weight at 365 days old and weight at 550 days old were 0.30+or-0.01, 0.23+or-0.01, 0.27+or-0.01 and 0.31+or-0.01, respectively. Meta-analysis techniques are recommended for polling of genetic parameters of zebu beef cattle.
