Problems solved by technology

Although ruminants themselves are less affected by aflatoxin, on the one hand, rumen microorganisms in ruminants are very sensitive to it, and feeding a large amount of feed containing mycotoxins for a long time will reduce the digestion and absorption capacity of animals. On the other hand, Feeding feed with high aflatoxin content will easily lead to excessive levels of aflatoxin in meat and dairy products, which is very unfavorable under the increasingly stringent food supervision

Abstract

The invention provides a microbial preparation for reducing the aflatoxin content of corn silage, and the microbial preparation comprises microorganisms selected from lactobacillus plantarum, bifidobacterium bifidum, lactobacillus rhamnosus and botrytis cinerea. In addition, the rising speed of the aflatoxin content in the aerobic exposure process can be inhibited.

Description

[0001] field of invention [0002] The application belongs to the field of microorganisms. Specifically, the application provides a microbial preparation for reducing the content of aflatoxin in corn silage, which comprises a microbial preparation selected from Lactobacillus plantarum, Bifidobacterium bifidum, Lactobacillus rhamnosus and Botrytis cinerea Bacteria microbes. Background technique [0003] Silage refers to the conversion of carbohydrates into organic acids mainly lactic acid through anaerobic fermentation of lactic acid bacteria attached to silage raw materials under sealed conditions, so that the pH drops and the growth of harmful bacteria is inhibited, so that the feed can be preserved and optimized for a long time process of its nutritional value. Since ancient times, silage has been one of the main sources of animal husbandry feed in cold regions. The feed that can be silaged mainly includes corn, alfalfa, barley, oats, sorghum, milk vetch, sugar beets, potat...
