Eighteen Murrah buffalo heifers were randomly distributed into three treatment groups each having six heifers on the basis of age and body weight i.e. T1 (control group, fed with conventional ration), T2 (fish meal supplementation by replacing conventional concentrate) and T3 (with 10 g commercial bypass Lysine per animal per day + 2 g commercial bypass Methionine per animal per day) for 90 days. The amount of concentrate mixture was given to each group in such a way that the experimental rations remain iso-proteinaceous. The results of the study revealed that after first fifteen days average daily weight gain were 622.22, 677.78 and 666.67 g/d in T1, T2 and T3, respectively. The data shows that after 60 days there was significantly higher (P<0.05) gain in T2 treatment which was similar to T3 as compared to control T1. The average daily gain then followed similar trend till the end of experiment. Average daily weight gains at the end of experiment, for the corresponding groups were 677.78, 844.44 and 777.78 g/d, respectively. Statistical analysis of data revealed that there was no significant difference in the dry matter intake among the different treatments. Overall DMI after 90 days was found to be 6.99, 7.04 and 7.02 kg/day in T1, T2 and T3 respectively. After first fifteen days FCR values were 10.86, 10.86 and 9.63 in T1 (control), T2 and T3, respectively. The results shows that after 60 days FCR values were significantly differ (P<0.05) in T2 and T3 treatments as compared to control T1. The FCR values then follow similar trend till the end of experiment. The FCR values at the end of experiment, for T1, T2 and T3 treatments were 11.83, 9.48 and 10.26, respectively.
