Growth and wool yield of 100 Nilagiri and 100 Synthetic (Nilagiri x Merino crossbred) lambs were studied under intensive and semi-intensive system of management. At the end of experiment, the lambs under intensive system gained more body weight than the semi-intensive system in both the genotypes. Lambs under intensive system produced an average of 0.157 kg more wool yield over semi intensive system. The manure yield was two times higher in lambs reared under intensive system compared to lambs in semiintensive system. Asum of Rs. 180 per lamb was spent as an extra cost of feeding to the lambs reared under intensive system over the semi-intensive system. It was concluded that the lambs under intensive system gained more body weight than the semi-intensive system.
