Description

technical field [0001] The invention relates to the technical field of aquatic product feed processing, in particular to a Chinese herbal medicine feed additive for improving the intestinal function of freshwater fish and its application. Background technique [0002] Intestinal microorganisms play a very important role in the growth and development of fish. A good intestinal microbial flora can help fish better digest and absorb nutrients and maintain the health of fish. A healthy intestinal microbial environment can regulate the immune function of fish and help break down indigestible cellulose, lignin, chitin and pectin after swallowing. And can prevent the colonization and spread of harmful bacteria in the intestinal tract. Because wild fish are in a water environment with high micro-ecosystem stability, they seldom get sick; while artificially raised fish are in a changeable micro-ecosystem, which is easy to create opportunities for opportunistic pathogens to cause mic...
