This study examined the effects of dietary inclusion of tanniferous leaves of Ficus infectoria as an organic protectant of proteins on the performance of lambs. The addition of condensed tannins (CT) up to 1.5 per cent in the supplement did not interfere with the nutrient utilization. Daily growth rate and wool growth for a period of 180d showed a significant (p<0.05) increase by the supplementation of CT @ 1.5% through F. infectoria leaves. Blood-biochemical parameters were similar among the dietary treatments except lower in serum urea concentration. The cell mediated immune (CMI) response was increased in all the CT supplemented lambs. It may be concluded that condensed tannins CT may have some stimulatory effect on the immune system of lambs.
