Abstract：The activity level of protease, amylase and cellulase from glandular stomach, gizzard, small intestine, large intestine, liver and pancreas of tree sparrows was analyzed respectively with enzyme analytical method. The results showed that the activity level of same digestive enzymes from different organs was distinguishing; the activity level of amylase and protease appeared the highest in pancreas, followed by glandular; the activity level of different digestive enzymes of the same organ was obviously diversed, the activity of amylase presented to be the highest, followed by protease, the lowest in cellulase. It has been suggested by the authors that the different activity level of the digestive enzyme is influenced by food composition and the living environment.
