饲料全维度评价技术OA

Current feed evaluation mainly focuses on nutritional value assessment,involving the content and bioavailability of nutrients.Based on the multi-dimensional evaluation concept and previous research achievements,this paper constructs a full-dimensional feed evaluation index system covering nutrients,nutritionally active substances,safety risk substances,physical properties,chemical properties,and biologi-cal characteristics of feed.The evaluation indicators,determination methods,and research progress of each dimension are reviewed,and the applications of this evaluation technology in raw material database con-struction,economic value assessment of feed ingredients,feed material classification,feed formula design,and compound feed optimization are explored.The full-dimensional feed evaluation technology realizes the evolution from single nutritional value evaluation to comprehensive performance index evaluation of feed,promotes the predictive and controllable development of compound feed evaluation,and provides evaluation indicators and technical support for accurate evaluation of feed ingredients,quality optimization of compound feed,and improvement of animal breeding benefits.
