Pig feed used for reducing pig dung stink, and preparation method thereof

Abstract

The invention provides a pig feed used for reducing pig dung stink, and a preparation method thereof, and belongs to the technical field of pig feed. The pig feed is mainly prepared from following raw materials, by weight, 60 to 80 parts of bean dregs, 20 to 25 parts of cassava dregs, 40 to 60 parts of puffed corn flour, 8 to 15 parts of shrimp meal, 2 to 3 parts of citric acid, 5 to 8 parts of vitamin, 30 to 40 parts of mixed mushroom bran, 0.3 to 0.5 part of nitrobacteria, 0.5 to 0.8 part of brevibacterium glutamicus, 0.2 to 0.3 part of mucor, 2 to 4 parts of an enzyme preparation, 5 to 10 parts of carbonized biomass, 20 to 30 parts of folium ginkgo powder, and 6 to 10 parts of herba centipedae. The pig feed is capable of providing pigs with comprehensive and sufficient nutrients, is convenient to be absorbed and digested, is capable of degrading intestinal tract waste residue by microorganisms, absorbing ammonia substances in intestinal tract and pig dung with functional raw materials, promoting growth of pigs via the cooperation effect of the raw materials, reducing pig dung stink, and improving the environment in hog houses.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of pig feed processing, in particular to a pig feed that reduces the smell of pig manure and a preparation method thereof. [0003] 【Background technique】 [0004] The modern pig farming industry is developing in the direction of high intensification and factoryization. The scale of pig farms is getting larger and larger, followed by a large amount of feces and urine produced by pigs, which produces serious stench. It not only pollutes the environment, but also affects humans and animals. It is healthy and restricts the normal development of the breeding industry itself. Pig manure not only contains a variety of harmful substances, but also produces stench. In the malodorous odor and harmful gas, it mainly includes nitrogen compounds, sulfide aliphatic compounds, etc. Especially ammonia, hydrogen sulfide and other gases are easily soluble in water, and can be absorbed by mucous membranes and conjun...

Problems solved by technology

However, the above-mentioned types of deodorants have certain shortcomings and deficiencies, such as the addition of large amounts of adsorption-type and fragrance-masking deodorants in the standard materials, or directly added to the feces or litter, and the ammonia gas is not fundamentally eliminated. Odor molecules, entering the soil with feces will easily increase the content of nitrate in the soil; chemical deodorants can convert odor molecules into odorless substances through reactions, but 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
