 ABSTRACT

Eighteen Murrah buffalo heifers were equally divided into three groups of equal number 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). 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 did not show any significant increase in average daily weight gain among the different treatments up to 45 days but 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 feed conversion efficiency (FCE) values were 10.21, 11.11 and 10.90 in T1, T2 and T3, respectively. The results did not show any significant difference in FCE values among the different treatments up to 45 days but after 60 days FCE values was significantly differ (P<0.05) in T2 and T3 treatments as compared to T1. The FCE values then follow similar trend till the end of experiment i.e. up to 90 days. The FCE values at the end of experiment, for control T1, T2 and T3 treatments was 8.58, 10.61 and 9.81, respectively. The present study concluded that feeding of commercial bypass amino acids and fish meal have beneficial effect on feed conversion efficiency of Murrah buffalo heifers.
