This study was conducted to estimate heritabilities and genetic and phenotypic correlations among growth traits (weaning weight, weight of 12 month, weight of 18 month, weight of 24 month). Growth data collected from steers (n=3,321) and 8,818 animals in pedigree were used for estimation of genetic parameters. Traits evaluated included live weight at 4 month (W4), 12 month (W12), 18 month (W18) and 24 month (W24). Parameters were estimated using an multitrait animal model and derivative-free restricted maximum likelihood procedures. Heritabilities estimated for growth traits at W4, W12, W18 and W24 were 0.21, 0.11, 0.08 and 0.14, respectively. Genetic correlations were in the range of 0.79 to 0.87. Phenotypic correlations were in the range of 0.16 to 0.81.
