The present experiment was conducted in semi-intensive management system to observe the effect of herbal additives amla (Emblica officinalis) and giloy (Tinospora cordifolia) either single or in combination on the wool yield and wool quality of Magra lambs. Twenty eight Magra lambs of 3-4 months of age were selected for conducting the feeding trial in semi-intensive system for 90 days. The lambs were randomly distributed into four experimental groups of seven lambs in each group in semi-intensive management system in a randomized block design (RBD) in such a manner that the initial body weights were remain similar in all the groups. Herbal feed additive Amla (Emblica officinalis) fruit powder with seed and Giloy (Tinospora cordifolia) stem powder were supplemented at level of 1.5g/kg body weight with concentrate as oral/feed supplemented in T1 and T2 group, respectively except control group and T3 in semi-intensive management system. Group T3 were supplemented with the combination of Amla (Emblica officinalis) fruit powder and Giloy (Tinospora cordifolia) stem powder at the level of 0.75g/kg body weight each with concentrate as oral/feed. The findings of the present study revealed that wool yield and other wool characteristics were not affected in all treatment groups under semi-intensive system by the supplementation of herbal feed additives in lamb ration but numerically highest improved in Giloy treated group.

Wool, Magra, Amla, Giloy, semi-intensive management system

The conclusion of this study is that many other factors such as genetics may have played a role in the results. Further research may be needed to explore alternative methods of improving wool production in lambs.
