Abstract
The invention discloses a biological mildew removing agent of livestock and poultry for feeds and an application thereof. The biological mildew removing agent comprises the following raw materials in parts by weight: 50-75 parts of compound strain fermentation substance, 6-12 parts of catalase, 8-10 parts of thymol, 5-8 parts of yeast cell wall polysaccharide, 2-5 parts of vitamin C, 2-5 parts of vitamin E and 1-2 parts of glucose oxidase. According to the invention, a brand new biological mildew removing agent is obtained by combining compound strain fermentation substance, catalase, thymol, yeast cell wall polysaccharide, vitamin C, vitamin E and glucose oxidase and performing reasonable matching. The biological mildew removing agent has excellent mycotoxin degradation and can greatly reduce the degradation effect of the mildew removing agent to the mycotoxin. Experiments prove that the degradation rates of the biological mildew removing agent to AFB1, ZEN and DON are respectively as follows: AFB1 97.81+/-0.09%, ZEN 93.11+/-10.22% and DON 97.48+/-12.35%; and the biological mildew removing agent has excellent degradation to FB1 and OTA, and the degradation rates are respectively as follows: FB1 64.315+/-0.11% and OTA 67.43+/-9.25%.
Description
technical field [0001] The invention relates to an animal feed additive, in particular to a livestock and poultry biological mildew remover for feed and its application. Background technique [0002] Mycotoxins are secondary metabolites of molds, which are widely found in food, feed and raw materials. Once animals eat feed contaminated by mycotoxins, it will cause adverse phenomena such as immunosuppression and reproductive disorders, resulting in major economic losses in animal husbandry. Moreover, mycotoxins can enter the human body through the food chain, causing potential teratogenicity, carcinogenicity, and mutagenesis. Therefore, the problem of mycotoxin pollution has increasingly become a major problem that cannot be ignored in modern agricultural production. Elimination of mycotoxins is of great significance to ensure animal health and give full play to the production potential of animals. [0003] At present, there are three main methods for removing mycotoxins: p...
