Abstract: Twenty four growing Egyptian buffalo male calves with an average of 15 months old and 330 kg LBW were divided to four experimental groups, where G 1 and G3 fed on ration content 70% CFM plus 30% com silage (CS) , and G2 and G4 fed on ration content 50% CFM plus 50% CS. Calves of G1 and G2 were previously (during growth stage) fed on 60% CFM plus 40% CS, while those of G3 and G4 were previously fed on 40% CFM plus 60% CS, published, (El-Ashry el al. 2007), this study was to evaluate the effect of two level of concentrate feed mixture and com silage in the ration on the finish growth phase of the fatting male buffalo calves on digestibility, some body measurements body condition score, rumen activity, some blood constituents. While, effect of the weight gain, feed and economical efficiency and carcass characteristics were calculated and compared among G1, G2, G3 and G4 in addition to the control group (R3) which fed on station ration calves: R3): fed on 64.5% % CFM plus 35.5% (16.64% rice straw plusI8.86% berseem hay). The different tested rations were formulated to cover the maintenance and production requirement according to El-Ashry allowances, (1980). The feeding experiment extended up to 120-150 days.
The result indicated that the buffalo calves on high CFM level recorded the highest digestion coefficients of DM, CP, EE and DCP value. While, the bunillo calves on low CFM level recorded the highest digestion coefficients of OM, CF, NFE and TDN value The final and daily gain of rumen girth increased significantly (P<0.05) with increasing the level of com silage in the rations. Calves fed high CFM level had the best-feed efficiency and economic efficiency. There were no significant dit1erences in carcass weight and dressing percentage between calves fed the different rations. The weights of carcass fat was increased significantly (P<0.05) with decreasing the level of CPM and increasing the level of com silage in the rations. From this study, it could be concluded that feeding Egyptian buffalo calves on G 1 and G3 fed on ration content 70% CFM plus 30% (CS), on DM basis had a beneficial effect on productive performance, teed and economic efficiency and carcass characteristic.
