Nutrition mechanism and application in animal feeds of amylase

Starch is one of the major nutrients in animal feeds and plays an important role in animal growth. Amylase, as a biocatalyzer to depredate starch, can improve utilization efficiency of grain starch and increase animal production. The research on applications of amylase in grain processing has great significance, but there was a lack of information in feed processing and animal nutrition. In this paper, the classification and current application of amylase were reviewed, and the development of amylase on animal production was also discussed.
