Description

Degradation equipment capable of effectively degrading biologically fermented feed toxin

Technical Field

The utility model relates to a fodder fermentation technical field specifically relates to a degradation equipment that can effectively degrade biological fermentation fodder toxin.

Background

The fermented feed has the advantages of aromatic smell, rich nutrition, good palatability, high digestibility and the like, so that the fermented feed is an excellent feed for dairy cows. The fermented feed can improve the milk production performance, improve the milk quality and promote the physical health of the dairy cows, and is widely used in dairy cow breeding, but the mould produced by fermentation can influence the quality of the fermented feed. Mould contamination in fermented feed comes mainly from two aspects: firstly, the feed is subjected to secondary fermentation in the taking process; secondly, the field pollution. The feed polluted by the mould not only causes the feed quality to be reduced and nutrient substances to be lost, but also seriously damages the digestive and immune systems of the cows. Therefore, the protection, inspection and management of mycotoxins must be enhanced for fermented feeds.

Mycotoxins are toxic secondary metabolites produced by molds during growth metabolism. For example, aflatoxin B1(AFB1), aflatoxin B2(AFB2) and the like are produced by aspergillus flavus after being stimulated by external environment oxidative stress, and Zearalenone (ZEA) and the like are produced by fusarium. Common toxinogenic molds in feed and grain include aspergillus (aspergillus flavus, aspergillus parasiticus, etc.), fusarium (fusarium graminearum, fusarium nivale, etc.) (Labuda, et al, 2005). One mold can produce multiple mycotoxins, such as fusarium graminearum can produce both ZEA and vomitoxin (DON). The fermented feed is possibly polluted by various mycotoxins, when the cellar is opened to take the fermented feed, air is contacted with the outer surface of the feed and enters the feed, so that the restrained aerobic microorganisms (mould, yeast and the like) are recovered and start to reproduce and breed, the temperature of the feed in the cellar rises along with the recovery, the microorganisms are further reproduced, and the feed is rotted and deteriorated quickly.

The existing toxicity-reducing means mainly comprises microwave, heat treatment, ultraviolet rays, water washing, rays and addition of an adsorbent, except for well preparing cultivation and harvesting time of forage grass and adding a fermentation microbial inoculum, but the toxicity-reducing effect of a single technical treatment means is not obvious, and the toxicity-reducing cost of multiple technical means is increased, so that a fermentation device which is simple and convenient to operate, economical and applicable is required, and not only can effective fermentation be realized, but also the toxicity of feed can be reduced.
