Problems solved by technology

However, the common feature of fresh slag feed is high water content. If it is not stored in time, it will easily spoil and deteriorate, which will not only waste feed resources, but also cause pollution to the environment.
At the same time, the production of slag feed is easily affected by environmental temperature, humidity and seasonal changes, which may easily cause an imbalance in the seasonal supply of slag feed in farms, and is limited by transportation distance and cost.
Traditional dry storage is easy to lose nutrients and increase fuel costs, and sun-dried storage is easily affected by weather and site

Embodiment 1

[0014] Take 10 tons of brewer's grains (85.3% water content) as an example for storage by adding feed-grade ammonium chloride:

[0015] 1) Calculate the required amount of ammonium chloride: calculate by 0.3% of the fresh weight of brewer's grains, and the total amount of ammonium chloride required is 30 kilograms;

[0016] 2) prepare ammonium chloride saturated solution: dissolve 30 kilograms of ammonium chloride in 75 kilograms of water;

[0017] 3) In the process of filling the brewer's grains, spray the ammonium chloride saturated solution into the mixture and store it;

[0018] 4) Judging from the quality and property changes of brewer's grains during storage, the storage time of brewer's grains has reached more than 1 year, and has a significant anti-fly effect during the storage period.

Embodiment 2

[0023] Take 25 tons of cassava residues (moisture content 81.8%) to store by adding feed grade ammonium chloride as an example:

[0024] 1) Calculate the ammonium chloride requirement: calculate by 0.4% of the fresh weight of cassava dregs, and the required ammonium chloride total amount is 100 kilograms;

[0025] 2) Prepare saturated solution of ammonium chloride: dissolve 100 kilograms of ammonium chloride in 250 kilograms of water;

[0026] 3) In the process of filling cassava residues, spray saturated ammonium chloride solution into the mixture and store after mixing;

[0027] 4) Judging from the quality and property changes of cassava residues during storage, the storage time of cassava residues has reached more than 1 year, and has a significant anti-fly effect during the storage period.

Abstract

The invention discloses a long-term storage method of a grain dreg type feed. The storage method is realized by adding feed-grade ammonium chloride (NH4Cl) into the grain dreg type feed according to a certain proportion. To ensure the storage effect, the ammonium chloride accounts for 0.2-0.5% of the fresh weight of the grain dreg, generally 0.3-0.4%. The method can be applied to grain dreg type feeds of which the water contents are within 20-95%, the storage period can be more than 1 year, and remarkable anti-fly effects are achieved; and the grain dregs stored by using the method are suitable for being used as feeds for ruminants such as cows and sheep. The long-term storage method is simple to operate and low in cost, and has a good application prospect.

Description

technical field [0001] The invention relates to a long-term storage method of dregs feed. Background technique [0002] Slag feed is a by-product of the brewing industry, sugar industry, food processing industry and other industries. my country's waste residues are rich in resources, with many types and large output. Only wine making, starch and fruit processing can produce hundreds of millions of tons of waste residues every year. Slag feed is generally rich in nutrients, and it is a cheap feed resource widely welcomed by livestock breeding enterprises. However, the common feature of fresh dross feed is high water content. If it is not stored in time, it will easily spoil and deteriorate, which not only wastes feed resources, but also pollutes the environment. At the same time, the production of slag feed is easily affected by environmental temperature and humidity and seasonal changes, which may easily cause an imbalance in the seasonal supply of slag feed in farms, and ...
