目的 为农业副产物资源在动物生产中的饲料化利用提供理论依据。 方法 查阅相关文献，简述农副产物发酵饲料的优势，综述农副产物发酵饲料在动物生产中的应用。 结果 利用微生物发酵农副产物，不仅能减少农副产物中的毒素和抗营养因子，提高农副产物的适口性，而且还能促进畜禽对农副产物营养成分的消化吸收等。 结论 微生物发酵技术可以促进农副产物的饲料化利用，为畜牧业的稳定发展提供了有力保障。

Objectives To provide a theoretical basis for the feed utilization of agricultural by-product resources in animal production. Methods The advantages of fermented feeds from agricultural by-products were briefly described and the utilization of fermented feeds from agricultural by-products in animal production was summarized based on reviewing relevant literature. Results The utilization of microbial fermentation of agricultural by-products can not only reduce toxins and anti-nutritional factors in agricultural by-products, and improve their palatability, but also promote the digestion and absorption of nutrients by livestock and poultry in agricultural by-products. Conclusions Microbial fermentation technology can promote the utilization of fermented feeds from agricultural by-products and provide strong support for the stable development of animal husbandry.
