The invention relates to an antibiotic-free animal fermented feed and a preparation method thereof. The invention uses grape pomace as the main fermentation raw material, mixes auxiliary components such as corn pomace, cottonseed cake, bean dregs, etc., and also adds citric acid. Bacterial liquid is fermented within the water content and pH value range of the specific fermentation mixture to obtain fermented feed without antibiotics. After feeding, it can improve the intestinal microbial balance of animals, enhance immunity, and improve the growth performance of animals. The prepared fermented feed can replace the role of antibiotics in the feed, and effectively solve the problem of feed safety. Under the optimized fermentation conditions, the invention obtains the fermented feed which can replace the feed antibiotic through a simple preparation method, and has low cost and easy industrialization. |
