Effect of Different Management Systems on Growth and Carcass traits of Post Weaned Male Kachhi Lambs

The experiment was performed to evaluate the effect of different management systems on growth traits and carcass characteristics of male Kachhi lambs. A total of 18 post weaned male lambs having three months of age were distributed into two groups (A & B), comprising nine lambs in each group. The lambs of group A & B were kept under intensive and semi-intensive management systems respectively. Initially the lambs were provided 15 days adaptation period, followed by 12 weeks experimental period. The average final body weight was recorded higher (P<0.05) in group B lambs as compared to group A lambs. Moreover, the higher (P<0.05) significant difference was also observed in body conformation with regards to body girth, length, and height of lambs in group B as compared to lambs of group A. The carcass weight and weights of neck, shoulder, thorax, loin and flank, legs, kidneys, and weight of liver of lambs in group B was recorded significantly (P<0.05) higher than the lambs of group A managed under intensive and semi-intensive management systems respectively. Based on the present study, it was concluded that weight gain, body length, chest girth and height at withers were significantly increased in the lambs of group B kept under a semi-inten-sive management system as compared to lambs in group A reared under intensive management system.
