| Abstract |
Thirty buffalo calves averaging 175 kg live body weight and aged 12 months were divided into 5 similar groups (6 animal in each) and randomly assigned to five rations during the 1st period (growing period, first 165 day of experiment) as follows:
R1: 67% concentrate feed mixture (CFM) + 33% rice straw (RS), as a control ration.
R2: 52% CFM + 25% RS + 23% berseem hay (BH).
R3: 41% CFM + 28% RS + 23% BH + 8% EI-Mufeed.
R4: 33% CFM + 14% RS + 53% maize silage (MS). R5: 22% CFM + 16% RS + 54% MS + 8% EI-Mufeed.
During the 2nd period (finishing period) all animals in the different groups were fed the same ration consisted of 57% CFM + 17% RS + 20% MS + 6% EI-Mufeed.
The obtained results indicated that inclusion of BH or MS with or without EI-Mufeed increased digestion coefficients of all nutrients. However, the feeding values presented as TDN and DE tended to increase, while DCP decreased as results of inclusion of MS and EI-Mufeed in the 4th and 5th rations. During the 1s1 and whole experimental periods, the highest daily TDN and DE and the lowest DCP intake detected with feeding MS with or without EI-Mufeed.
In the 1st period the average daily gain in the 2nd 3rd , 4th , and 5th groups were higher by 10.13, 13.92, 21.19 and 27.85% than the 1st group. The overall means of daily gain were higher in the 2nd, 3rd, 4th and 5th groups than the control group by 3.49, 6.98, 11.63 and 16.28% respectively.
The better feed and economic efficiency during 1st and whole experimental periods were attained by calves fed MS with or without EI-Mufeed followed by those fed BH with or without EI-Mufeed, while the control ration showed the lowest feed efficiency .
There were significant differences in fasting body weight, hot carcass weight, boneless meat weight and boneless meat to bone ratio, color intensity and moisture capacity, ether extract and ash contents, while dressing percentage, physical characteristics and protein content were nearly similar for the different experimental groups.
