Pig feed capable of deodorizing, and preparation method thereof

Abstract

The invention provides a pig feed capable of deodorizing, and a preparation method thereof, and belongs to the field of pig feed preparation. The pig feed is mainly prepared from, by weight, 60 to 80 parts of bean dregs, 15 to 20 parts of sugar beet pulp, 20 to 30 parts of rice bran, 10 to 20 parts of fly maggot powder, 2 to 3 parts of citric acid, 5 to 8 parts of vitamin, 25 to 35 parts of mixed mushroom bran, 0.5 to 0.8 part of nitrobacteria, 0.3 to 0.5 part of corynebacterium glutamicum, 0.2 to 0.3 part of mucor, 1 to 3 parts of an enzyme preparation, 6 to 9 parts of carbonized biomass, 20 to 30 parts of folium ginkgo powder, and 3 to 5 parts of waste tea powder. The pig feed is capable of providing pigs with sufficient and comprehensive nutrients, and can be absorbed easily; decomposition of intestinal tract waste residue is realized with microorganisms, ammonia substances in intestinal tract and excrement are absorbed by functional raw materials; the combined action of the raw materials is capable of promoting growth of pigs, reducing the stink of pig dung, 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 deodorized pig feed 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 conjunctiva of humans and animal...

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
