In a CRD model, thirty two ram labs (ave. 3 months age) were randomly divided into 4 groups with 8 lambs in each group and was allotted to one of the following dietary regimes in which the feed restriction was followed at 4 levels (%) viz- 0 (control-T1), 10(T2), 20(T3) and 30(T4). Restriction was done for 8 weeks followed by realimentation for 4 weeks. During restriction period, the ADG and FCR are higher and lower (P<0.05) respectively, for T1 as compared to other treatments where as a reverse trend as observed during realimentation phase. The digestibility coefficients (%) for DM, CP, OM, NFE increased linearly (P<0.05) from T1 to T4 indicating maximum digestibility at 30% feed restriction in restriction period where as in realimentation phase except for CP, DM and ADF (P<0.05) none of the parameters were found to be significant. It can be concluded that feed restriction upto 30 % level resulted in improved the performance in terms of growth, nutrient digestibility, carcass yield, reducing the cost/kg gain and cost of production in ram lambs.
