Thirteen newly born Murrah buffalo calves were utilized for the experiment and were randomly allocated to suckling and weaned groups. The allocation resulted in 7 suckling calves as well as 6 calves under weaning system of management. The overall least squares’ means (LSM’s) for LWB’s of Murrah buffalo calves at birth, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30 and 31 weeks of age were 30.87±1.13, 37.81± 2.37, 41.50±2.23, 44.02±2.29, 46.65. ±2.35, 49.31±2.57, 52.54±2.85, 54.46±2.82, 58.65±3.10, 63.56±3.02, 67.73±3.19, 71.35±3.46, 76.53±3.53, 79.16±3.31, 84.04±3.75, 89.59±3.89, 93.49±3.83, 99.25±4.42,103.20±4.48, 108.22±5.29, 113.45±5.34, 118.12±5.25, 123.41±4.89, 127.53±4.68, 127.20±4.69, 134.41±5.37, 145.18±3.84, 149.59±3.85, 152.95±3.73, 164.42±5.46 and 168.48±5.46 kg, respectively. The effect of rearing system was significant (P≤0.05) on LWT’s at 2, 13-15, 24, 27 and 28 weeks of age whereas it was highly significant (P≤0.01) on LWT’s at 16-23 weeks of age. The birth weights were almost same in both the systems of rearing and these were 30.87±1.09 and 30.92±1.17 kg, respectively, for suckling and weaned calves. The significant increase in body weights was initially noticed in suckling system calves at WT2 (45.58±2.37 kg) over their weaned counterparts (38.11±2.12 kg). The effects of sex and sex (within the rearing system) on weekly live body weights were non-significant.
