Results showed that dietary supplementation with 1% zeolite and all level of silver nanoparticles had better feed conversion ratio than the basal diet on d 22-42  (P<0.05). Diets supplemented with silver nanoparticles at 0.5% and 0.75% level increased villi length and villus/crypt ratio significantly compared to the basal diet (P<0.05). In comparison to the basal diet, diets supplemented with silver nanoparticles decreased crypt depth. On d 21, broiler chickens fed diets supplemented with 0.5% and 0.75% silver nanoparticles had lower coliforms bacteria population compared with basal diet and basal diet supplemented with 1% zeolite (P<0.05). In conclusion, the present results showed that zeolite coated with silvernanoparticles can improve feed conversion ratio, intestinal morphological characters and decrease coliforms population in broiler chickens and it can be considered as a growth and health promoters.
