The current experiment was conducted to study the histology of duodenum in broilers fed with different levels of inclusion of cashew apple waste (CAW) as well as enzymes. The study was carried out for a period of 42 days. A sum total of two hundred and ten day-oldvencobb-400 broiler chicks were randomly divided into seven groups with three replicates of 10 chicks in each group. Group 1 (G1) received control diet prepared as per BIS (2007) recommendations. G2 and G3 birds received diet prepared with 5 and 10 per cent CAWwithout any enzyme supplementation, respectively. G4 and G5 birds received 5 per cent CAW with supplementation of 500 g/ton and 750 g/ton of enzymes, respectively. G6 and G7 birds received 10 per cent CAW with supplementation of 500 g/ton and 750 g/ton ofenzymes, respectively. It was found that, histomorphological features like villus height and thickness of tunica mucosa were found to be higher in group (G4) where 5 per cent CAW with NSP degrading enzymes at 500 g/ton were fed significantly (p<0.01) when compared to all other groups. The number of goblet cells was observed to be significantly (p<0.01) lesser in the group (G4) when compared to all other groups.
