Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial application field> The present invention reduces malodor generated from manure by reducing the water content of manure excreted from animals such as livestock using malt. The present invention relates to a method for removing malodor of manure using malt.

<Background of the Invention and its Problems> Increasing population has made it absolutely necessary to increase food production. On the other hand, as the standard of living has improved, their diet has also been favoring high-protein milk, chicken eggs, meat and the like, and accordingly large-scale chicken farms, pig farms, milk ranches and beef cattle farms have been operated.

The manure produced in these large-scale feed stations is extremely large, and the manure collected in the breeding house and the odor generated in the process of transporting them are large, leading to social problems that hurt the living environment. . In addition, countless flies occur around large poultry houses, especially in summer, but these larvae, maggots, grow in watery poultry manure.

Conventionally, chemical deodorants, biological deodorants, deodorants extracted from natural products, etc. have already been developed to remove such malodors in livestock houses, but they have an economic burden on users. In addition, there is a problem that the chemical treatment process is complicated.

<Means and Actions for Solving Problems> Therefore, the method for removing malodor of manure using malt according to the present invention, in order to solve the above-mentioned problems, adds a large amount of malt powder or extract thereof to feed. The more it is done, the higher the odor removal effect, but at least 1 to 10
wt.%, or by spraying malt powder or an extract thereof directly on manure or sewage outlets, sewage treatment tanks, etc., to reduce the moisture content of manure excreted from animals such as livestock using malt. In this case, malt is used to remove malodor generated from manure.

In other words, the feed supplied to livestock is more or less different, and the raw materials used there are mainly corn, wheat, corn, soybean meal, rapeseed meal, wheat skin, defatted husk, fish meal, tallow, etc. Calcite, calcium phosphate, salt, vitamins, etc., and trace amounts of other disease preventive and therapeutic agents. In other words, the main component of feed is sugar (starch,
Polysaccharides), proteins and fats.

Therefore, while these organic substances are decomposed, hydrogen sulfide (H ₂ S), ammonia (NH ₃ ), methane (CH ₄ ), carbon dioxide (CO ₂ ), indole (Indole), and skatole (Skato)
l), 5-aminoacetophenone, phenol and various other trace gases are generated, and all types except carbon dioxide gas cause odor.

The organic substance decomposes to generate a gas with a bad smell. If this gas is continuously decomposed or chemically converted, a substance having no bad smell can be obtained. That is,
When hydrogen sulfide turns into sulfate, ammonia turns into acetate, and methane turns into carbon dioxide, the bad smell disappears.

In the present invention, an enzyme agent is used which promotes the decomposition of starch and protein, which are the main components of feed, and induces continuous decomposition of secondary products produced after these are degraded, thereby producing a substance having no odor. did.

The enzyme agent used in the present invention is malt powder (Malt Powde
r) and malt extract. Malt is germinated from wheat and has the property of producing enzymes. As wheat for malt, wheat that has passed for 6 to 8 weeks after harvest is used, oxygen is supplied to wet wheat grains, germination occurs at an appropriate temperature, and enzymes are generated to produce starch, protein, and organic phosphoric acid. It has the property of decomposing salts and fats. The enzymes formed in malt are Cytase and Amylase.
e), maltase, protease (Proteas)
e), phosphatase (Phosphatase), oxidase (Oxidase) and catalase (Catalase).

Among them, amylase and protease play the following roles. That is, amylase is produced in saliva and animal pancreas in addition to malt as an enzyme that hydrolyzes starch. When such an amylase is added to a feed and consumed by an animal, it has the effect of promoting digestion, increasing the utilization efficiency of the feed and reducing the moisture content of manure.

Proteases produced with amylase also
Proteinase (Protinase) and Peptidase (Pepti
dase), proteinase has the function of breaking the internal structure of the peptide bond, and peptidase has the terminal free α
Acting on an amino group or a terminal free α-carboxy group,
Since it has a function of cleaving the peptide chain, a good effect can be obtained even when this enzyme is added to feed.

Other enzymes also play important roles in the metabolic processes of organisms. That is, malt can be said to be a complex enzyme preparation.

When malt powder or malt extract is added to feed and used, digestion is promoted by the combined action of these enzymes, feed utilization efficiency is enhanced, moisture content in manure is reduced, fly generation is reduced, and malodor is reduced. It can be removed and the environment can be greatly improved.

Malt itself acts as a nutrient source to promote the growth of livestock such as cattle and chickens.

Even when malt powder or malt extract is directly sprayed on manure, the decomposition of the decomposition product is promoted and the moisture content of manure is reduced, so that the malodor can be removed.

<Example I> As a result of an experiment based on the above grounds, when 10 wt.% Of malt powder was added to the feed, the digestibility was reduced, the water content of the manure was reduced, and the manure was free of foul odors. The effect of reducing the dose could be obtained.

<Example II> When malt powder was added at 1 to 9 wt.% To the feed, as in Example 1, the digestibility increased, the moisture content of the manure decreased, and the manure did not have a bad smell. The effect of reducing the dose of was obtained.

<Example III> Further, as a result of directly spraying malt powder on human excrement and livestock excrement, the water content similarly decreased and the malodor was removed.

<Example IV> Furthermore, in the case of chickens, as a result of directly spraying at least about 1 to 10 g of malt powder on the basis of chicken dung per bird per day, not only the removal of offensive odors, but also the generation of flies was significantly reduced.

<Example V> As a result of directly administering an appropriate amount of the malt powder to the sewage port and the filth tank, the removal rate of organic substances was improved, and the odor was remarkably removed.

<Effects of the Invention> According to the method for removing malodor of manure using malt according to the present invention, the more malt powder or extract thereof is added to the feed, the higher the malodor removal effect is, but economical. By adding at least 1 to 10 wt.% In consideration of various aspects, or by spraying malt powder or its extract directly on manure or sewage outlets, sewage treatment tanks, etc., it is economical and simple to collect and remove manure. Transport is facilitated, feed utilization efficiency can be increased, and malodors can be removed.
