A study was conducted to estimate the pre- and post-weaning relative growth rates (RGR) in Sirohi goats born during 2005 to 2017 under field conditions. The overall least-squares mean for pre-weaning (0-3M) and post weaning (3-12M) relative growth rate were 1.79±0.02 and 0.263±0.005 percent per day, respectively. Sire, type of birth, sex of kid and cluster had highly significant (P≤0.01) effect on both pre- and post-weaning relative growth rates whereas season of birth and parity had highly significant effect (P≤0.01) only on pre-weaning relative growth rate. Year of birth had highly significant effect (P≤0.01) on pre-weaning relative growth rate whereas its effect was significant (P≤0.05) on post-weaning relative growth rate. Heritability estimates for pre- and post-weaning relative growth rate were 0.58±0.06 and 0.40±0.06. Genetic and phenotypic correlation between two traits was negative.
