Microbial fermented feed for reducing odor of pig manures of black pigs and preparation method thereof

Abstract

The present invention discloses a microbial fermented feed for reducing odor of pig manures of black pigs. The feed is prepared from the following raw materials: canna edulis powder, pumpkin powder, potato powder, tapioca powder, acorn powder, bran residues, fruit peels, soybean meal, fish meal, bone meal, shellfish powder, crop straws, tea residues, traditional Chinese medicinal residues, compound enzymes, a microbial preparation and brown sugar. The present invention also discloses a preparation method of the microbial fermented feed. The microbial preparation can convert ammonia gas into odorless substances, improves gastrointestinal digestive functions of the black pigs, inhibits various bacteria, reduces the odor of the pig manure, reduces diseases of diarrhea, etc. of the black pigs,and accelerates the growth and fattening of the black pigs. By inhibiting urease activity, the microbial fermented feed reduces the production of the ammonia gas in the intestines and manures, at thesame time can also supplement deficiency of endogenous enzymes in the pigs, and increases the enzymes that the black pigs cannot synthesize. These enzymes and the beneficial micro-organisms containedin the fermented feed can improve the beneficial micro-organisms in the intestines of the black pigs, can improve the intestinal digestive capacity of the black pigs and reduces the content of harmful gases of ammonia gas, sulfuretted hydrogen, etc. in the pig manure.

Description

technical field [0001] The invention belongs to the technical field of feed production, and in particular relates to a microbial fermented feed for reducing the odor of black pig manure and a preparation method thereof. Background technique [0002] With the development of modern animal husbandry and the expansion of market demand, large-scale pig farms in my country have developed rapidly, and the production of live pigs has continued to rise. Followed by a large amount of excrement and urine produced by pigs, it produces serious stench, which not only pollutes the environment, affects the health of humans and animals, but also restricts the normal development of the breeding industry itself. Pig manure not only contains a variety of harmful substances, but also produces stench. The problem of environmental pollution by pig manure and other wastes has also become increasingly prominent. These foul odors and harmful gases mainly include nitrogen compounds, sulfide aliphati...

AI Technical Summary

Problems solved by technology

But the above-mentioned types of deodorants all have certain shortcomings and deficiencies, such as the addition of large amounts of adsorption-type and fragrance-masking deodorants in the routine materials, or directly added to the excrement or litter, and do not fundamentally eliminate ammonia gas, etc. Odor molecules, entering the soil with feces will easily increase the content of nitrate in the soil; chemical deodorants will convert odor molecules into odorless substances through reactions, but they still fail to fully utilize nutrients, and discharge into the soil is likely to cause Secondary pollution; the activity of enzyme preparations and microorganisms is easily affected by high temperature in the process of feed processing, and the effect is not good in practical application
