LAMB PRODUCTION UNDER DIFFERENT SYSTEMS OF MANAGEMENT ON RANGELANDS OF BALOCHISTAN

This study was conducted to determine the effect of three management systems on the production of Balochi lambs on rangelands of Balochistan province of Pakistan. Growth rate of Balochi lambs under three management systems i.e. T1–Extensive system (grazing only), T2–Semi-extensive system (grazing plus daily feed supplementation for three months @ 0.58 kg/lamb/day) and T3–Intensive system (experimental ration only @ 1.25 kg/lamb/day) was observed. All three treatments differed (P 0.05) in their effect on growth rate of lambs. T1 resulted in average daily weight loss of about 26 g/lamb. Lambs under T2 were able to maintain and put on average daily weight of 20 g/head and T3 lambs gained weight @ 66 g/head/day. This study revealed that the Balochi sheep possess propensity to survive under harsh conditions.
