In an attempt to determine effect of incorporation of herbs i.e., Bael (Aeglemarmelos) and Giloy (Tinospora cordifolia) alone and in combination at different levels in the ration of broilers to assess the effect of feeding of herbs alone and in combination as feed additive on growth and feed conversion of broilers, a feeding trial of six weeks was conducted, using Bael, Giloy and their combination at 0.5, 1.0 and 1.5 % levels, using 300 broiler chicks (cobb-400) in completely randomized block design. The experimental starter and finisher rations contained 22.40 and 21.10% C.P, respectively. The body weight, body weight gain, feed consumption, feed conversion ratio, were recorded for all ten treatment groups.Significant effect of dietary treatments i.e., incorporation of Bael, Giloy and their combination at different levels on body weight, body weight gain were observed whereas on feed consumption, feed conversion ratio the effect was revealed to be non significant.The findings of present study in respect of all parameters included in the study indicated that incorporation of Bael and Giloy alone and in combination could be effective in the ration of broiler chicks without any adverse effect on growth and feed conversion. The optimum level adjudged from present study for growth and efficient feed conversion are 1.0-1.5% for Bael, 0.5-1.0% for Giloy and 1% for Bael and Giloy combination.
