Live body weight data from 288 Murrah buffalo female calves maintained at the Livestock Research Center, Karnal, Haryana, India, born in the period between 2000 and 2009 were used for this study. Data were analysed using least-squares procedures. The overall mean for birth weight of Murrah buffalo female calves was 32.32±0.31Kg.The mean body weight at 3rd, 6th, 9th, 12th , 15th , 18th , 24th , 30th and 36th months of age pooled over season, periods and birth weight were 65.0 ± 0.51, 108.78 ± 0.97, 139.07±1.43, 174.82±1.80, 211.20±2.20, 255.21±2.30, 338.39±2.56, 405.75±3.29 and 470.50 ± 3.87 kg, respectively. The overall mean values of body weight at sexual maturity and weight at first calving of Murrah buffaloes were 413.60±3.68 Kg and 569.60±5.13Kg. Period of calving influenced the weight significantly almost all month of ages in this study. The calves born during the summer season were generally heavier and gained more body weight than those born in other seasons. Birth weight of calves influenced the body weight significantly at 3rd, 18th months of age only and also influences the weight at sexual maturity and weight at first calving. The phenotypic parameter estimates indicated that the more than 6th month of body weights can be used as a selection tool for improvement of growth traits considering its highly positive phenotypic correlations with succeeding growth traits.
