The present study was carried out to evaluate the effect of VamDia Forte as Intestinal function modulator for broilers. Two hundred and seventy day old Cob-400 broiler chicks having similar body weight (43g) were randomly allotted to three dietary treatments viz C, T1 and T2 containing VamDia Forte at 0, 0.5 kg/ton and 1 kg/ton respectively in the basal ration. No histological changes were seen at the age of 7th day in all the groups. On 14th day, in T2 group, the villous length of the duodenum was increased in comparison to that of the control birds. Though the crypt number was increased their depth was decreased. In T3 group, the duodenal villi showed maximum length and breadth with wide laminae propria having more capillaries. The crypts depth was decreased with fully developed cryptal epithelial cells. No signifi cant difference was observed in respect of blood biochemical profi le (albumen, globulin, blood urea and blood urea nitrogen). From the results it can be summarized that the VamDia Forte is most effective as intestinal gut modulator for broilers @ 1kg/ton.
