Histochemical studies were conducted on the pancreas of twenty four apparently healthy chabro chickens irrespective of sex. The birds were divided into four age groups . Group- 1, Group- 2, Group- 3 and Group- 4. The reaction for PAS was similar in the stromal tissue in various groups but in stromal blood vessels it varied among the groups.
