Description

[0002] The present invention relates to a composition for feed use and a method for preparing the same,

More particularly, the present invention relates to a composition for feed use such as food wastes and homozygous foliage including homozygous animals.

In recent years, insects, such as Donghae, have been used to make feeds for various livestock, and the use of insects has been widening. Dongae is an insect belonging to the arthropods insect gut, paralysis, etc. The body is black and the body length is 13 ~ 20 mm. It lives in dirty water or dung. Habitats are distributed worldwide in the United States, India, Australia, Vietnam and Korea.

The adult larva is about 15 ~ 20 days old. The size of adult larva is about 20mm. One adult catches about 1000 eggs and digests manure, food waste, etc.. In addition, microorganisms such as bacteria and fungi in the organic matter are ingested or suppressed by microbial secretion by antibiotics. Adults do not feed and do not harm humans and livestock, unlike other flies, because they consume only water. The larvae of Dongae are composed of 42% protein and can be used as feed for livestock and fish, and their feces can also be used as good quality compost.

In general, Donghae habitat is an organic waste, animal carcass, livestock meal, plant residue, and food waste, and food waste is mostly used as food when raising Donghae.

However, the food waste used in the case of raising the households has a very high moisture content, so that there is a difficulty in consuming the household waste and the like, and there is a disadvantage that it is not effective in the treatment of the food waste. In addition, even when collecting the fecal alteration soil after the rearing of the dumplings, there is a disadvantage that it is difficult to collect the fecal soil and to isolate the larvae because the fecal alteration soil obtained by using the food waste to cultivate the dumplings has a high water content .

Korean Patent No. 10-1759518 discloses a feed composition including organic wastes, fermentation control additives, and the like, and further discloses that a moisture control additive composed of dried sawdust is further contained, Dried sawdust has a disadvantage in that it is costly to manufacture feedstuffs such as dumplings because of high unit price.

Thus, the present inventors have found that, without the need for a separate moisture control additive such as dried sawdust, it is possible to effectively treat food wastes and to recycle the fecal soil, and to develop feeds for breeding ducks with excellent nutritional status and high quality And have completed the present invention accordingly.

Korean Patent No. 10-1759518

It is an object of the present invention to provide a feed composition which can reduce the manufacturing cost of a feed for rearing on a home soil without requiring a separate moisture control additive such as dry sawdust, .

It is another object of the present invention to provide a method for manufacturing a feed for a food such as food wastes and Donga et al. That does not require a separate moisture control additive such as dry sawdust, Which is environmentally friendly, economical, and the like. In addition, the present invention provides a feed composition such as a mixture of a wet food feed of residual porridge in the form of porridge, which can be used only for insect breeding without permission of a separate waste, and a powdered soil, and the like.

In order to solve the above problems, the present invention provides a composition for feed use, such as food wastes and homosexual wastes including homosexual wastes.

The food wastes may be residual food wastes that have been boiled for 30 minutes to 60 minutes at a temperature of 80-100 < 0 > C.

The feed composition may have a water content of 60 to 75%.

The feed composition may be 70 to 85% by weight based on the total composition, and the food wastes may be 15 to 30% by weight based on the total weight of the composition.

The present invention also relates to a food waste; And a method for producing a composition for feed use such as hominis including a step of mixing a fertilized soil of Dongae and the like.

The food wastes may be residual food wastes that have been boiled for 30 minutes to 60 minutes at a temperature of 80-100 < 0 > C.

The feed composition may have a water content of 60 to 75%.

The feed composition may be mixed with 70 to 85% by weight of the food wastes, and 15 to 30% by weight of the wastes of the food wastes based on the total composition.

 The feed composition according to the present invention has the effect of controlling the moisture content of the feed such as Donghae by using the fecal soil of Dongae and the like without adding a separate moisture control agent such as dried sawdust. As a result, it is possible to improve the breeding environment of the dwellings and the like, and it is possible to more easily ingest the diets and the like, and the problem of disposal of food waste can be more effective than the conventional case.

In addition, since the feed composition according to the present invention utilizes a self-producing fungus soil without using a moisture control material such as high-end dry sawdust, it is possible to reduce the cost in producing the feed, which is very economical. Furthermore, the composition according to the present invention has an advantage of being environmentally friendly because it can effectively treat food waste and recycle the fecal soil.

In addition, the fecal soil obtained in the case where the composition for feed according to the present invention is used for breeding drought and the like has a relatively low water content as compared with the case where the existing food wastes are used for rearing dirt and the like, There is an advantage that collection of the fecal soil can be easily performed.

One embodiment of the present invention is a feed composition such as food wastes and homosexuals including fecal soil of the same family.

In the present invention, the term " food waste " may mean food waste discharged from a home or a restaurant, animal fat discharged from a livestock farm, and mixtures thereof, but is not limited thereto.

In the present invention, " fecal soil of Dongae and the like " is produced in the process of growing a larva to Dongae, for example, it may be obtained by treating egg, larva or mixture thereof in Dongae and the like. The water content of the fecal soil may preferably be 20%, but is not limited thereto.

The modified soil according to the present invention can be used to control the water content of the feed composition,

There is a disadvantage that when sawdust, which is one of the materials that can be used as a moisture control material in the related art, is used as a moisture control material, it is high-end. Dry feeds, which are another ingredient, must be paid for in the same way as when using sawdust, so there is a separate purchase cost. Gas generated during the production of dry feeds may cause secondary environmental pollution, And the water absorption is not easy. Also, there is a disadvantage that the size of the larvae raised by using the dried feed is smaller than the normal level.

According to the present invention, the submerged soil according to the present invention is to solve the above-mentioned disadvantages, and since the submerged soil of Dongae and the like is already in a state where the first fermentation is completed, it is not only suitable for recycling as a moisture control material, It is possible to reduce the cost.

The term " feed " in the present invention means a substance supplying organic or inorganic nutrients necessary for maintaining the life of the individual and raising the individual. The feed may include nutrients such as energy, protein, lipid, vitamins, and minerals required by the individual to feed the feed, but the feed is not limited thereto. The feed refers to a subject to be fed, Living organisms that can be used in the present invention are not limited, and mean the same for the purpose of the present invention.

In the present invention, the food waste is not particularly limited, but it may be boiled at a temperature of 80 ° C or higher, preferably 80 to 100 ° C for 30 minutes or more, preferably 30 minutes to 60 minutes. Specifically, the food wastes may be residual food wastes prepared by boiling residual food waste or the like at a temperature of 80 ° C for 30 minutes or longer.

In the case of using the remaining food wet feed, which is a form of porridge as a food waste, there is an advantage that it is not required to obtain permission for the final disposal of waste, unlike the case where the cake state of the food waste or the crushed raw material is fed as a feed , And the composition for feed can be used only for notification of insect breeding without separately permitting the waste to be fed to the farm, such as the mixture of wet food with residual food, which is a form of porridge according to the present invention, and fecal soil, , And the like can be mass-produced.

The water content of the food waste may preferably be 80 to 90%, and most preferably 85%. It is preferable that the food waste has a water content in the above range because there is a need to separately supply water when the water content of the food waste is low.

In the present invention, the feed composition may have a water content of 60 to 75%, preferably 65 to 75%, and more preferably about 70%. When the water content of the feed composition is lower than 60%, there is a problem that the feeding activity becomes dull and the nutrient intake is lowered. When the water content of the composition is higher than 75%, the collected water is largely separated from the larvae There may be a difficult problem.

In the present invention, the feed composition may be preferably 70 to 85% by weight, more preferably 70 to 80% by weight, and most preferably 75 to 80% by weight based on the total composition, And the like can be mixed in an amount of preferably 15 to 30% by weight, more preferably 20 to 30% by weight, and most preferably 20 to 25% by weight. When the content of the fecal soil is within the above range, the nutritional composition of the composition is excellent, and it is possible to more easily take the feed of Donga et al. There is an advantage that collecting of the fecal variant can be easily performed after the rearing of the father and the like.

Another embodiment of the present invention is a method for producing a feed composition, such as a homogenate, which comprises a step of mixing food wastes and fecal soil of Dongae and the like.

In the production process according to the present invention, the food waste is not particularly limited, but may be obtained by boiling at a temperature of 80 DEG C or higher, preferably at a temperature of 80 to 100 DEG C for 30 minutes or more, preferably 30 minutes to 60 minutes have. Specifically, the food wastes may be leftover food wastes prepared by boiling residual food wastes or the like at a temperature of 80 ° C for 30 minutes or longer. The water content of the food waste may preferably be 80 to 90%, and most preferably 85%. It is preferable that the food waste has a water content in the above range because there is a need to separately supply water when the water content of the food waste is low.

According to the production method of the present invention, the feed composition may have a water content of 60 to 75%, preferably 65 to 75%, and more preferably 70%. When the water content of the feed composition is lower than 60%, there is a problem that the feeding activity becomes dull and the nutrient intake is lowered. When the water content of the composition is higher than 75%, the collected water is largely separated from the larvae There may be a difficult problem.

In the production method according to the present invention, the feed composition is preferably used in an amount of 70 to 85% by weight, more preferably 70 to 80% by weight, and most preferably 75 to 80% by weight, based on the whole feed composition, % By weight, and the subdivided soil of the petals and the like may preferably be mixed in an amount of 15 to 30% by weight, more preferably 20 to 30% by weight, most preferably 20 to 25% by weight. When the content of the fecal soil is within the above range, the nutritional composition of the composition is excellent, and it is possible to more easily take the feed of Donga et al. There is an advantage that collecting of the fecal variant can be easily performed after the rearing of the father and the like.
