Title: Effects of Varying Protein Sources with High Molasses /Urea Rations on Fattening Zebu Calves
Author: Abbas Siddig, EL Fadil
Abstract: Twenty one year old Kenana and Butana calves were used in this study. The calves were allotted to four treatment groups; A (control) fed on sorghum-based diet and test groups B, C and D fed on molasses-based diets plus different byproduct protein sources, cotton seed cake, sesame cake and groundnut cake respectively. Feeding period lasted for 90 days. On conclusion, animals were slaughtered and carcass analyzed. All test groups (molasses-based) were inferior to the control (sorghum-fed). Their feed conversion ratios were 2 to 3 times that of the control (7.14). Best feed conversion among test groups was that of group C (13.87) fed on sesame cake. Total weight gain was similarly lower compared to that of the control (63.33 kg), Weight gain of group C (6.00 kg) on sesame cake was slightly higher than either group D (5.63 kg) on groundnut cake or group B (4.38 kg) on cotton seed cake. The dressing-out percentages of test groups were lower (51.48 to 52.15) than the control group (54.45). The weight of non-carcass components, carcass joints and carcass tissues of test groups were similarly lighter than the control group. The source of protein had no effect on the proportions of carcass components.
