Problems solved by technology

Especially the aflatoxin in corn and peanut meal is the highest. If they are all destroyed, it will be a great loss. If the feed with aflatoxin exceeds the standard, the animal will die of acute poisoning after direct feeding, or the aflatoxin will be fed continuously. Feed with excessive aspergillus toxins will lead to loss of appetite, liver tissue necrosis and death of animals
[0005] Therefore, the development of aflatoxin detoxification products is also a hot spot of research by scientific and technological workers at home and abroad. The main methods such as catharsis with magnesium sulfate after animal poisoning can only treat the symptoms but not the root cause. There are also methods in China that directly produce and degrade aflatoxins by microbial fermentation. Monomer biological enzymes, but because the fermentation activity is not high, and the working condition is in an alkaline environment, it is easy to be inactivated in an acidic environment, so there has been no industrial application

Abstract

The invention belongs to the technical field of feed additives, and concretely relates to a detoxifying enzyme of aflatoxin in a feed. The aflatoxin detoxifying enzyme comprises cutin protease, neutral protease, polyphenol oxidase, hemicellulase, glucose oxidase, lipase, glycosidase, a Rhizoma Polygoni Cuspidati extract, mung bean powder, vitamin A and vitamin D. The detoxifying enzyme of aflatoxin in the feed can decompose aflatoxin contained in the feed, also can hydrolyze macromolecular substances in the feed, and provides micro-molecular nutritional substances which can be digested and utilized for animals.

Description

technical field [0001] The invention belongs to the technical field of feed additive enzymes, in particular to a detoxification enzyme for aflatoxin in feed. Background technique [0002] Aflatoxins are metabolites produced by Aspergillus flavus and Aspergillus parasiticus. When grains are not dried in time or stored improperly, they are often easily contaminated by Aspergillus flavus or Aspergillus parasiticus and produce such toxins. [0003] There are more than a dozen types of aflatoxins found so far, such as B1, B2M1, M2, G1, G2, etc. Among them, B1 is the most common in feed, and it is also the most toxic one. Aflatoxins are classified as Class 1 carcinogen, 68 times more toxic than arsenic, second only to botulinum toxin. [0004] In agricultural production, corn with aflatoxin exceeding the standard is not uncommon. Especially the aflatoxin in corn and peanut meal is the highest. If they are all destroyed, it will be a great loss. If the feed with aflatoxin exceed...
