Abstract

Growth performance and carcass traits of finisher lambs were compared under intensive feeding (G I) and grazing with supplementation (G2). Initial weights were higher (P <0.05) in G1 than that in G2 whereas, in the 2 groups the finishing weights were similar because the total gain in the experimentand average daily gain were higher in G2 than that in GI, The feed conversion efficiency was, however, similar in the 2 groups. Pre slaughter weight,fasted weight, empty live weight and hot carcass weights were similar in the 2 groups. Like wise the dressing yield in terms of pre slaughter weight was similar in the 2 groups while the dressing yield in terms of empty liveweight was higher (P <0.05) in G1 than that in G2. Depot fat weight and per cent fat in dissected half carcass was also significantly (P <0.01) higher in G I compared to G2. Cut proportion of leg, loin, and rack was similar in G I and G2 while the proportion of neck and shoulder was higher in G I and breast and fore shank was higher in G2. It is concluded from the study that growth response of lambs was better under grazing with 300 g concentrate supplementation compared to intensive feeding while the intensively fed lambs deposited more depot.
