The invention relates to the field of feed, in particular to a method for measuring xylanase added to feed. In this method, the feed sample to be tested is pre-cooled and dialyzed with acetate buffer, and then the enzyme activity is determined. The micro-determination method of xylanase added in feed according to the invention avoids the inactivation of xylanase in the extraction process through the pretreatment of feed samples, reduces the detection limit of xylanase, and eliminates the interference of background interference. Therefore, the content of xylanase added to the feed can be accurately determined. |
