For this purpose, 16 male buffalo calves were involved in this experiment. They were kept at Animal Nutrition Center, Rakh Dera Chal. They were divided into four groups A, B, C and D with 4 animals in each group. The group A was given simple fodder ad libiti urn and the group B was given simple fodder ad libitiurn and was injected with recommended dose of bst hormone (125mg/animal) with trade name of Boostin 250 s/c at an interval of 14 days, while the animals of group C were given simple fodder ad hhitiurn + 1% b. wt. In group D animals were given fodder ad libitiurn + 1% b.wt. Experimental ration + bst injection s/c at the interval of 14 days. Daily fodder and feed intake was recorded. The weight of each animal was recorded after fourteen days. The research trial continued for 3 months. The feed efficiency of group A to D was 8.08, 4.89, 5.91 and 4.79 with an average daily weight gain of 0.3 11, 0.486, 0.619 and 0.711 kg, respectively. The dressing percentage was 47.04, 48.35, 48.59 and 49.76 for group A to D, respectively. The percentage of blood, heart and lungs were 4.66, 4.67, 4.69, 5.16 percent and 0.5, 0.47, 0.56 and 0.57 percent and 1.55, 1.23, 1.31 and 1.38 for group A to D, respectively. The percentage of liver, spleen and kidneys were 1.8, 1.17, 1.61, 1.53 percent and 0.32, 0.44, 0.33, 0.42 percent and 0.33, 0.34, 0.32, 0.35 percent for group A to D respectively. The value for other components like mesenteric fat, feet, head and skin were 1.8, 1.84, 1.87, 2.4 percent for mesenteric fat and 3.04, 3.38,, 2.93 and 2.64 percent for feet and 5.03, 5.13, 4.67 and 4.57 percent for head and 10.5, 9.46, 10.32 and 10.0 percent for skin of group A to D, respectively. The percentage ratio of meat, bone, fat and other tissues were 49.5, 51.6, 50.5 and 49.5 percent, 34.15, 33.0, 34.5 and 35.15 percent, 7.5, 9.25, 8.0 and 9.5 percent 4.20, 3.85, 4.5 and 5.1 percent for group A to D, respectively. The chemical composition of meat revealed 74.37, 73.0, 74.87 and 76.30 percent moisture, 19.75, 20.75, 21.On and 20.50 percent for crude protein, 8.15, 9.0, 9.15 and 9.07 percent for ether extract, 6.08, 6.6,6.15 and 7.0 percent for ash in group A to D respectively. The costs of 1 kg meat production from group A to D were 123.40, 103.40, 98.97 and 107.00 rupees respectively. This revealed that minimum cost of meat production was in group C, where as calves in group A proved most expansive meat producer among the groups. The overall data suggests that use of bST has positive effect on meat production but economic feasibility is still questionable.

The present study was conducted to see the effect of Bovine somatotropin on total weight gain, fortnightly weight gain, feed efficiency and carcass composition of buffalo calves. For this purpose, 16 male buffalo calves were involved in this experiment. They were kept at Animal Nutrition Center, Rakh Dera Chal. They were divided into four groups A, B, C and D with 4 animals in each group. The group A was given simple fodder ad libiti urn and the group B was given simple fodder ad libitiurn and was injected with recommended dose of bst hormone (125mg/animal) with trade name of Boostin 250 s/c at an interval of 14 days, while the animals of group C were given simple fodder ad hhitiurn + 1% b. wt. In group D animals were given fodder ad libitiurn + 1% b.wt. Experimental ration + bst injection s/c at the interval of 14 days. Daily fodder and feed intake was recorded. The weight of each animal was recorded after fourteen days. The research trial continued for 3 months.
