abstract
In an attempt to assess the effect of Giloy (Tinospora cordifolia) and Neem (Azadirachta indica) alone and in combination on growth performance in Marwari lambs, an experiment was conducted for 12 weeks on 42 Marwari male lambs and divided into seven groups, six lambs in each group in a randomized block design. The lambs of T₁ group were provided only basal diet (grazing + ad lib. fodder + 400 g concentrate per lamb per day) and were kept as control group and lambs of all other treatment groups were provided basal diet with herbal supplementation i.e. 0.5 per cent Giloy stem powder in group T₂, 1.0 per cent Giloy stem powder in group T₃, 0.5 per cent Neem leaf powder in group T₄, 1.0 per cent Neem leaf powder in group T₅, 0.25 per cent Giloy stem powder along with 0.25 per cent Neem leaf powder in group T₆ and 0.5 per cent Giloy stem powder along with 0.5 per cent Neem leaf powder in group T₇. At the end of experiment, the highest ADG was recorded in lambs of group T₇ among all treatment groups. At the end of experiment it appears that incorporation of 0.5 per cent Giloy stem powder along with 0.5 per cent Neem leaves powder can be used as a part of strategy to be adopted to improve growth performance of lambs in arid zone of Rajasthan.
