A kind of pig feed mycotoxin degradation adsorbent and its application

Abstract

The invention discloses a mycotoxin degradation adsorbent, which consists of Bacillus subtilis, Lactobacillus plantarum, Lactobacillus acidophilus, Leuconostoc lactis, Lactobacillus delbrueckii, Lactobacillus fermentum, Lactobacillus salivarius, vitamin C, vitamin E, Composition of Astragalus, Zinc Methionine, Potassium Chloride, Cinnamon, Clove, Capillary, Artemisia annua, Wild Chrysanthemum, Plantago Seed, Yeast Cell Wall and Phytase. The mycotoxin degrading adsorbent has multiple functions of inhibiting the production, degradation and adsorption of various common mycotoxins in the feed, and can also improve the immunity of pigs and promote the excretion of poisons. It has comprehensive excellent performance and has positive effects on the production performance of piglets Significant effect, can reduce morbidity, increase daily gain, improve feed digestibility, and reduce feed-to-meat ratio. Moreover, the usage amount is low and effective, it has no adsorption effect on drugs and other nutrients, it can be biodegraded after discharge, and it does not contain pollutants, so it has good application value for aquaculture.

Description

technical field [0001] The invention belongs to the technical field of feed additives. More specifically, it relates to a pig feed mycotoxin degradation adsorbent and its application. Background technique [0002] Mycotoxins are anti-nutritional factors present in feed materials and compound feeds. They are secondary toxic metabolites produced by different types of fungi, mainly including: aflatoxin, ochratoxin, T-2 toxin , Ophiotoxin (Diaeetoxyscirpenol, DAS), Deoxynivalenol (DON, vomitoxin, fumonisin and zearalenone, etc. Mycotoxins affect almost every organ of the body, especially the liver, kidney , oral cavity, gastrointestinal tract, spleen and nervous system. It affects the feed intake and body weight of pigs, and reduces the feed conversion rate. It leads to vulva swelling, abnormal lactation, infertility, abortion, rectal and vaginal prolapse, and some cause Pulmonary edema, nervous disorders, and increased susceptibility to disease. Among them, trichothecenes suc...

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 use in actual production

There are many reports on the use of microbial fermentation to remove mycotoxins, such as the conversion of AFB1 into other products, but this conversion is usually slow and incomplete, and the safety of the converted product is still inconclusive. Whether it can be used in practice To play a role in production, systematic and perfect research is needed
