Traditional system of buffalo meat production is inefficient; animals destined for slaughter are mostly culled and old stock. Male calves are not reared specifically for producing meat but they are kept only for milk let down in villages and are slaughtered even at 6-7 days of age in peri- urban areas. So far very little work has been done to evaluate the tremendous meat production potential of buffalo calves with a particular plan of nutrition. Present study related to the use of a growth promoters treatment trial of about three months in duration to further accelerate the meat production. Twenty Nili-Ravi calves of approximately the same age and weight were selected for the research purpose. The animals were randomly divided into four equal groups (A, B, C and D), which were given four different treatment, such as, Ralgro, Boostin-250, M2 Hormone and control (non implanted) for group A, B, C and D respectively. The basal diet consisted of concentrate ration @ 1% of body weight along with chaffed green fodder ad lib. In each group, feed offered and refusal was recorded on individual basis. The results of study revealed that animals given M2 Hormone performed better as compared to other treatment groups. Among four treatment groups, highest (43.4 ± 12.00 kg) weight gain was observed in M2 Hormone group while, lowest (35.4 ± 12.5 kg) weight gain was found in control group. As far as feed intake is concerned, highest (429.79 ± 28.22 kg) feed intake was observed in Ralgro group while, lowest (412.83 ± 50.56 kg) feed intake was found in M2 Hormone group. Out of four experimental groups, calves of M2 Hormone group showed best feed conversion ratio (12.40 ± 3.01) while, the feed conversion ratio in calves of Ralgro, Boostin-250 and Control group was 12.79 ± 1.99, 14.14 ± 5.87 and 14.43 ± 2.54 respectively. Economic analysis per kg weight gain revealed that M2 Hormone group had the lowest cost of production in rupees (110.23 ± 3.79) per kg weight gain, where as highest cost of production (136.63 ± 4.72) was found in control group. On the basis of the results of this study it is concluded that M2 Hormone can be utilized as an alternate for our conventional fattening practices as it can increase body weight gain. The additional benefit of this compound is that it can be given in feed and does not have to be injected or implanted in the body. It is suggested that further trials with M2 Hormone be carried out on different age and sex groups of buffalo and cattle in order to evaluate its effects on the performance of the animals.

Pakistan is second largest buffalo holding country in the world having 29 million buffalo. Traditional system of buffalo meat production is inefficient; animals destined for slaughter are mostly culled and old stock. Male calves are not reared specifically for producing meat but they are kept only for milk let down in villages and are slaughtered even at 6-7 days of age in peri- urban areas. So far very little work has been done to evaluate the tremendous meat production potential of buffalo calves with a particular plan of nutrition.
