Lipase and clostridium butyricum enzyme containing freshwater fish feed additive and production method

Abstract

The invention belongs to a feed additive, and particularly relates to a lipase and clostridium butyricum enzyme containing freshwater fish feed additive. The lipase and clostridium butyricum containing freshwater fish feed additive is characterized by comprising 99.5-99.8% of basic feed and 0.2-0.5% of lipase and a clostridium butyricum enzyme complex enzyme preparation. The novel feed additive containing lipase and clostridium butyricum enzyme complex enzyme preparation can supplement, perfect and balance feed nutrition level so as to increase feed conversion ratio and food intake, animal breeding and development are promoted, animal reversibility is improved, body immunity is enhanced, survival rate is increased, and the lipase and clostridium butyricum enzyme complex enzyme preparation is a novel freshwater fish feed additive which is safe, healthy and efficient as from a natural green raw material.

Description

[0001] (1) Technical field: [0002] The invention belongs to a feed additive, in particular a freshwater fish feed additive containing lipase and butyric acid bacteria. [0003] (2) Background technology: [0004] Since the discovery of antibiotics by Fleming in the United Kingdom in 1929, it has brought tremendous changes to human production and life. The addition of antibiotics to animal feed can be traced back to the 1950s. Antibiotics can prevent animal diseases, promote animal growth, It has played an active role in improving the quality of livestock and poultry products. However, with the wide application of antibiotics as feed additives, its drawbacks have gradually emerged, such as causing the normal flora of the animal’s gastrointestinal tract to become imbalanced, causing side effects such as drug resistance and drug residues, and the residual drugs in animal products have seriously affected The treatment and inheritance of human diseases have brought harm to human health...

Problems solved by technology

[0006] Butyric acid bacteria are a kind of anaerobic bacteria with endophytic spore structure, good stability, not affected by gastric acid, bile acid, etc., easy to store in vitro at room temperature, and have strong tolerance to a variety of antibiotics. It has achieved good curative effect in intestinal diseases such as diarrhea and constipation, but it is still rarely used in animal husbandry.
