| Abstract |
Fifteen male Friesian calves with average body weight of 150± 14 kg and 8±0.94 month of age were used in this study. Calves were randomly distributed into three similar groups (five for each). The experimental rations were formulated as follows: ration 1 (R1): 63 % concentrate feed mixture (CFM) + 37 % clover hay (CH) (control), ration 2 (R2): 52.5 % CFM +7.5% soybean meal (SBM)+40% CH and ration 3 (R3): 47 % CFM +11% SBM+42% CH.
The partial replacement of CFM by SBM increased the CP% of rations 2 and 3. The CP concentration of the tested rations was 13.6, 15.6 and 16 6% for R1, R2 and R3, respectively. Nutrients digestibility tended to be higher (P<0.05) when SBM was supplemented at 11% than 7.5%. The TDN%, ME (Mcal/kg) , NE (Mcal/kg) and g CPI / ME Mcal were higher (P<0.05) with feeding on R2 or R3 than R1. while the TDN; CP ratio was higher (P<0.05) for R1 than R2 and R3. likewise, digested d
