The experiment was carried out using a completely randomized design on 12 Lai Sind young bulls with twenty months of age, weighting 186 - 194kg to examine the effects of supplementing ensilaged casava leafy tops at different levels, i.e. 0 percent (control)
20 percent (treatment 1) and 30 percent (treatment 2) DM in fattening ration on their performance. Daily DM and CP intake increased with increasing levels of ensilaged casava tops.1 Daily weight gain was highest in treatment 2 (779.30 g/day), followed by treatment 1 (646g/day), and lowest in control group (563g/day). Feed consumption ration varied from 9.48 to 11.35 kgDM/kg weight gain. It was concluded that ensilaged cassava leafy tops are a suitable source of green feed with high protein in fattening ration of cattle.
