Detoxification agent for vomitoxin in biodegradable feed and preparation technology thereof

Abstract

The present invention discloses a detoxification agent for vomitoxin in a biodegradable feed and a preparation technology thereof. The detoxification agent comprises the following raw materials: 40-60 parts of bentonite, 20 parts of immune polysaccharides, 10-20 parts of a free radical scavenger, and 20-30 parts of a vomitoxin degrading bacillus subtilis powder agent. A preparation method of the bacillus subtilis powder agent comprises the following steps: 1) original strains are subjected to a seed liquid activation and a mother culture is conducted in a primary fermentation tank loaded with a culture medium; 2) a mother culture liquid is subjected to an amplification culture in a second fermentation tank loaded with a LB culture medium; and 3) the bacterium body and the fermentation liquid are separated, the separated fermentation liquid is concentrated, and the concentrated fermentation liquid is dried to prepare the vomitoxin degrading bacillus subtilis powder agent; and the powder agent is combined with the two raw material mixtures in the above parts by weight to obtain the finished products. The detoxification agent has the degradation rate of the vomitoxin at 95% or more, is high in degradation efficiency, and avoids the defects of adsorbents. Besides, the immune polysaccharides and free radical scavenging components are added in the products, so that the detoxification agent can play the functions of protecting liver and improving the immunity of body, and is obvious in effects.

Description

technical field [0001] The invention belongs to feed additive technology, and more specifically relates to a detoxification agent for degrading vomitoxin in animal feed through biotechnology and a preparation process of the detoxification agent. Background technique [0002] Deoxynivalenol: Usually produced by the fungus Fusarizin that grows on cereals such as wheat, corn, barley, and hay. Toxic effects of vomitoxin include: vomiting, reluctance to eat, gastroenteritis, diarrhea, immunosuppression, and hematological disorders; [0003] Mycotoxin adsorbent: absorb part, a small amount, and specific toxins physically, and excrete them from the body without changing the properties and chemical structure of the toxins; [0004] Feed mycotoxins: secondary metabolites produced by molds, which have negative effects on animal growth rate, body organs, reproductive performance, production performance, etc. [0005] At present, the pollution of raw materials in our country is relati...

Problems solved by technology

However, due to the many types of mycotoxins in this method, the enzyme system is complex and complete, and it is easily affected by the function of the animal's digestive organs; in addition, due to the lack of heat resistance of the enzyme, it is easy to inactivate during the feed processing process, and the cost is high, and it is difficult to Promote the
