Abstract

The invention provides a feed additive for preventing grass carp nutritional fatty liver. The feed additive is prepared from the following raw materials by weight percent: 45 to 65% of traditional Chinese medicine fermentation extract, 15 to 25% of choline chloride, 10 to 20% of L-carnitine and 5 to 10% of vitamin, wherein the traditional Chinese medicine fermentation extract is mainly prepared byfermenting herba houttuyniae, dendrobium officinale kimura ex migo, radix astragali seu hedysari, fructus crataegi and pericarpium citri reticulatae. The additive can be directly added into fish feeds, can maintain a normal physiological function of a liver tissue, can perform nutrition regulation on fat metabolism and finally prevents liver and gall syndromes to guarantee fish health.

Description

technical field [0001] The invention belongs to the technical field of feed additives, and in particular relates to a feed additive for preventing nutritional fatty liver of grass carp. Background technique [0002] Grass carp, belonging to Cyprinidae, Yaluo subfamily, grass carp genus, commonly known as grass carp and grass root, is one of the famous "four major fishes" in my country. It is deeply favored by people and is a kind of seafood that people like to eat most. Grass carp aquaculture is the largest marine aquaculture industry in my country. Grass carp is the most prone to disease, mainly suffering from enteritis, red skin, etc., which brings great difficulties to grass carp breeding. In addition, hemorrhagic disease is also an infectious disease caused by reoguanidine virus that grass carp is very susceptible to. During the process, all fish from fingerlings to adult fish are susceptible to the disease. The disease has a very high incidence rate and a very high mort...
