| At present, microbial fermented feed is one of the hot spots of feed industry and aquaculture, and it is also an important condition for green and safe breeding. Study on microbial fermented feed in China began as early as 1990s. Recently, it has developed rapidly in animal husbandry, and more diversification in its production and application forms. In aquaculture, part of the daily diet is replaced with microbial fermented feed or fed directly after complex microbial fermentation. Because it contains live bacteria and related metabolites, it can further improve the nutrient absorption of feed, and improve the production performance of animals, prevent and cure diseases and improve the breeding environment. Microbial fermented feed will play an absolutely necessary role in replacing antibiotics in feed, raising high-quality animals, and preventing diseases in livestock and poultry in the future. In this paper, the concept of microbial fermented feed, its mechanism of action and the latest research status of its application in aquaculture and animal husbandry were explained, which will provide reference for the development of microbial fermented feed products and new technology. |
