Overview

This International Standard specifies the determination of phytase activity in feeding stuff samples, including feed raw materials from plant origin, compound feeds (complete, complementary, mineral feeds), premixtures and feed additives. The method has been validated in an interlaboratory test for the determination of phytase activity in complete feed, complementary feed including mineral feed, premixes, and feed additives. The responsible German standardization committee is Working Committee NA 057-03-03 AA "Futtermittel" ("Animal feeding stuffs") at DIN Standards Committee Food and Agricultural Products (NAL).
