Abstract: Twenty- four male buffalo calves averaging 275.3 kg were used in feeding trial to study the effect of feeding two sources of carbohydrate on their performance. Three animal groups (8 animals each ) were assigned to fed 2% of live body weight (LBW) concentrate feed mixture containing 30% sorghum grains and 15% yellow corn plus 15% sorghum grains in the experimental groups A, B and C respectively. Rice straw was fed at 1% of LBW of animals in the experimental groups. Feeding trial lasted for 145 days, during which, three metabolism trial were carried but to determine the feeding value of the experimental rations.
Data revealed that averages daily feed intake as DM were 9.93, 9.96 and 10.17 kg for animals fed rations A, B and C, respectively. Daily TDN intake recorded 6.33, 6.32 and 6.60 kg versus 0.71, 0.70 and 0.73 kg as DCP for the respective rations. The higher feed intake as DM, TDN, and DCP was observed with animals fed ration C ( containing yellow corn plus sorghum grains). The digestibility of DM, OM, CP and EE for ration C were significantly ( P<0.05) higher than the other groups, being 78.14, 79.18, 70.04 and 76.18%, respectively, while digestibility of CF (48.45%) and NFE (73.46%) for ration C was significantly ( P<0.05) lower than those rations. Feeding values as TDN were 63.71 , 63.45 and 64.94% for rations A,B and C , respectively, versus 7.12, 7.06 and 7.12 % as DCP for the respective rations. However, significant differences in TDN or DCP among different rations were not found. Averages daily gain were 814,809 and 804 g. for animals fed rations A,B and C, respectively, showing no differences among the different groups. However, animals fed ration A had higher daily gain and they were more efficient to utilize TDN per Kg gain (7.771 kg TDN/kg gain). Animals fed ration B showed the lowest feed cost to give one kg. Gain(4.2221 L.E) and the highest economical efficiency.
It could be concluded that there were no significant differences between ration A (containing yellow corn) and B (containing sorghum grains) with respect to daily gain and feed efficiency. However, using sorghum grains in ration of buffalo calves as carbohydrates source resulted in lower feed cost/kg. Gain and higher economical efficiency.
