Pig feed mycotoxin degrading adsorbent and application thereof

Abstract

The invention discloses a mycotoxin degrading adsorbent, which contains bacillus subtilis, lactobacillus plantarum, lactobacillus acidophilus, leuconostoc lactis, lactobacillus delbrueckii, lactobacillus fermenti, lactobacillus salivarius, vitamin C, vitamin E, radix astragali, zinc methionine, potassium chloride, cassia bark, clove, oriental wormwood, folium artemisiae argyi, sweet wormwood, wild chrysanthemum flower, semen plantaginis, yeast cell wall and phytase. The mycotoxin degrading adsorbent disclosed by the invention has multiple effects including generation inhabitation, degradation and adsorption on various common mycotoxins, and can additionally boost immunities of pigs and promote excretion of toxic substances; the mycotoxin degrading adsorbent has excellent comprehensive performance and plays a remarkable role on productivities of piglets, and the mycotoxin degrading adsorbent can reduce disease rate, improve daily gain, increase feed digestibility and reduce feed conversion ratio. Moreover, the mycotoxin degrading adsorbent is low in dosage but effective and free from adsorption on drugs and other nutrient substances, and the adsorbent can be biologically degraded after being secreted and avoid pollutants; and the mycotoxin degrading adsorbent has good application value in breeding industry.

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
