Genetic parameters for birth, weaning, 6,9 and 12 month weights in a Baluchi sheep flock were studied. The genetic parameters were estimated by Restricted Maximum Likelihood method in an Animal Model. The heritability of birth weight, weaning, 6,9 and 12 month weights were 0.45(±0.02), 0.29(±0.029), 0.27(±0.03), 0.24(±0.05) and 0.33±(0.04) respectively. The Genotypic and phenotypic correlations of birth weight - weaning weight, birth weight - 6 month weight birth weight - 9 month weight, birth weight - 12 month weight, weaning weight - 6 month weight, weaning weight - 9 month weight, weaning weight - 12 month weight, 6 month weight - 9 month weight, 6 month weight - 12 month weight and 9, month weight - 12 month weight were (0.74 and 0.41), (0.71 and 0.36), (0.71 and 0.35), (0.62 and 0.31), (0.97 and 0.72), (0.93 and 0.66), (0.91 and 0.58), (0.96 and 0.79), (0.94 and 0.68) and (0.96 and 0.82) respectively.
