Method for evaluating feeding activity of enzyme preparation

The invention provides a method for evaluating the feeding activity of an enzyme preparation. The method comprises: feeding animals with a feed added with a to-be-evaluated enzyme preparation while setting a control group; taking the manure of the fed animals, and respectively obtaining the intestin...

Zusammenfassung:	The invention provides a method for evaluating the feeding activity of an enzyme preparation. The method comprises: feeding animals with a feed added with a to-be-evaluated enzyme preparation while setting a control group; taking the manure of the fed animals, and respectively obtaining the intestinal flora conditions of the fed animals through a 16S rDNA sequencing method; and comparing to the control group, and evaluating whether the intestinal flora conditions of the fed animals have the positively regulated feeding activity. The invention further provides a method for comprehensively evaluating the feeding activity of an enzyme preparation, wherein comprehensive evaluation is performed by combing the intestinal flora conditions of animals and the trait indexes of the fed animals. According to the present invention, the completely-new enzyme preparation feeding effect evaluation method is established by using the metagenome technology from the animal intestinal flora field, such that the blank in the evalu
