Problems solved by technology

[0005] In addition, industrial large-scale cultivation of Cordyceps fungus mostly adopts liquid submerged fermentation. After the fermentation is completed, the mycelium is extracted by solid-liquid separation. The fermented liquid that belongs to it needs to be sterilized and discarded, which not only wastes resources but also increases costs.

Abstract

The invention belongs to the technical field of agriculture, and relates to a feed additive containing hirsutella sinensis culture and a preparation method of the feed additive. The feed additive is a dried product of a fermentation broth obtained by carrying out liquid submerged fermentation and solid-liquid separation on the hirsutella sinensis [Hirsutella sinensis Liu, Guo, Yu, et Zang] strain. The method has the following advantages that: (1) the animal production performance and the product quality can be improved; (2) no harm is caused to human health, and excrement of animals does not cause potential pollution harm to the environment; and (3) the feed additive can effectively enter gastrointestinal tracts to play a role, and the palatability of a feed is not influenced. and (4) incompatibility does not occur or rarely occurs, and bacteria are not easy to generate drug resistance to the feed additive.

Description

technical field [0001] The invention belongs to the field of agricultural technology, and in particular relates to a feed additive containing Mortierella sinensis culture and a preparation method thereof. Background technique [0002] There are many epidemic diseases in poultry breeding production. In order to control bacterial and viral infections, feed additives are generally added with a large amount of antibacterial and antiviral drugs; in order to promote the growth and fattening of livestock and poultry products, farmers often add hormone drugs in the production process , The phenomenon of drug abuse in violation of regulations is extremely common, and a series of safety incidents caused by this are too numerous to enumerate. [0003] The abuse of antibiotics in the breeding industry has increased the difficulty of animal disease prevention and control, and has directly or indirectly endangered human health. For example, drug residues in animal and animal products can...
