Abstract

The invention discloses a mold inhibitor for a fermentation bed and a preparation method for the mold inhibitor. The mold inhibitor consists of a composite chemical preparation and a composite microbial inoculum, wherein the composite chemical preparation is prepared by mixing an organic matter and an inorganic matter, and the composite microbial inoculum is prepared by performing single-strain pure fermentation on microbes and mixing. The mold inhibitor has the advantages that by the mold inhibitor, the removal rate of molds in the fermentation bed is over 90 percent, the adsorption rate of mycotoxins is 70 percent, the harm of the molds and the mycotoxins to poultry are reduced, the problem that livestock and poultry are poisoned by the molds or the mycotoxins due to environmental factors or feed factors in the feeding process is solved, and an effect of medicinal treatment is achieved, so that the problem that intestinal florae of the livestock and the poultry are unbalanced and the problem that antibiotics are abused in the conventional breeding process of the livestock and the poultry are solved.

Description

technical field [0001] The invention relates to a composite mold inhibitor, in particular to a mold inhibitor for poultry manure fermentation beds and a preparation method thereof, belonging to the field of mold inhibitors. Background technique [0002] The development of ecological breeding has promoted the development of poultry fermentation beds, but the poultry manure contains a lot of water and the fermentation bed is very low, so mold pollution is easy to occur. Mold and mycotoxins are extremely harmful to livestock and poultry, so the research and development of mold inhibitors and mycotoxin removal agents for fermentation beds is imminent. [0003] Domestic fermented bed poultry breeding technology has just started in recent years, and no specific reports have been seen on the study of antifungal agents in fermented beds. However, a lot of work has been done on the anti-mildew work of feed at home and abroad. In order to prevent the loss of nutrients during feed sto...
