Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention generally relates to a feed suitable for fattening livestock, especially cattle, goats, sheep, pigs, chickens and the like, and a method for producing the same. It relates to a koji-mixed feed that has made it possible. Further, the present invention relates to a koji-mixed feed that can be produced at low cost and can be stored for a long period of time.

[0002]

2. Description of the Related Art Conventionally, corn, soybean, barley, hay, molasses, beet pulp, bran and the like have been used as feed for fattening livestock. Providing early growth of livestock is in line with the requirements of livestock breeding farmers, but feeding high-nutrition feeds for the purpose of increasing livestock will cause diarrhea in the livestock and rather inhibit growth. There was a problem. Therefore, it was thought that there was a natural limit to the nutritional value that could be fed and the rate of livestock gain. In addition, it is conceivable to increase livestock and reduce the price of feed by increasing the amount of low-priced and high-nutrition bran, but in ruminants, since bran has a high phosphorus content, Feeding a large amount of bran could cause death of livestock due to ureteral stones. For this reason, conventional bran has been considered to have a limit of about 5% of the total feeding amount. For livestock such as pigs and chickens, when a large amount of organic waste such as garbage is given, the amount of oil contained in the waste may lead to yellowing of the livestock and deterioration of meat quality such as tender fat. It had been.

[0003]

SUMMARY OF THE INVENTION In livestock fattening,
In view of the demand for early weight gain and increased resistance to diseases such as diarrhea, the present invention provides a feed that promotes fattening of livestock and at the same time improves meat quality without causing any adverse effects such as ureteral stones and diarrhea. Further, a feed which can reduce costs is provided.

[0004]

SUMMARY OF THE INVENTION It is a main object of the present invention to provide a koji-mixed feed and a method for producing the same, which at least partially eliminate the above-mentioned conventional problems. Another object of the present invention is to provide a koji-mixed feed that has a high nutritional value and promotes fattening of livestock while at the same time causing no adverse effects such as ureteral stones and diarrhea, and a method for producing the same. Another object of the present invention is to provide a method for producing a koji-mixed feed that uses organic waste as a feed without causing lipid yellowing, soft fat or the like. A further object of the present invention is to provide a koji-mixed feed capable of maintaining the production cost at low cost and a method for producing the same. Still another object of the present invention is to provide a koji-mixed feed suitable for ruminant animal fattening and a method for producing the same. Still another object of the present invention is to provide a feed suitable for fattening pigs and chickens and a method for producing the same. According to the first aspect of the present invention, a koji mold is mixed with two or more feed ingredients selected from the group consisting of fibrous feed, cereals, and organic waste, and the koji mold is grown. And a method for producing a koji-mixed feed. In the above, regarding ruminants,
In particular, there is provided a method for producing a koji-mixed feed in which cereals or organic wastes are added to fibrous feed, particularly bran, to which koji mold is added and grown. Until now, the feed intake of bran has been limited to about 5% due to obstacles due to phosphorus content. However, the feed produced by this method does not cause any obstacle and can provide an inexpensive feed. In addition, for livestock such as pigs and chickens, a method for producing a koji-mixed feed obtained by adding a cereal or a fiber feed to organic waste and adding and growing a koji mold is provided. Conventionally, feeding high quality nutritional feeds to livestock has a risk of causing disorders such as diarrhea. However, feeds produced in this way provide nutritious feeds,
Livestock gain can be promoted without causing any obstacles. In addition, organic waste that is discharged in large quantities and is difficult to treat can be effectively reused. Further, it is possible to eliminate a decrease in meat quality caused by feeding organic wastes with a high oil content. As described above, in the present invention, koji is added to a mixture of two or more kinds selected from fibrous feed, cereals or organic waste, and the mixture is grown to effectively produce an inexpensive and nutritious feed. It becomes possible. Here, Aspergillus is Asp.oryzae, Asp.awamori, Asp.sojae, for example,
It is preferably selected from the group consisting of Asp.oryzae.kawachii, Asp.awamori.kawachii. Further, after the growth of the above-described koji mold, a fibrous feed, a cereal, an organic waste, or a mixture of two or more selected from these may be further added. Further, as a method for more preferably solving the above-mentioned problem, a method of adding koji mold to bran, then growing the koji mold to produce bran koji, and mixing and fermenting the bran koji with cereal or organic waste. Is provided. Furthermore, there is provided a method for producing a koji-mixed feed in which one or more general feeds selected from barley, rice, soybean, corn, hay, molasses, and beet pulp are further mixed with the koji-mixed feed. You. In this case, even if the amount of the feed containing the koji is 5% by weight or more of the whole feed, fattening can be performed without causing a problem such as health disorder, and preferably 30% by weight or less of the whole. It is.

[0005] The present invention also relates to a fibrous feed, cereal, or the like having a water content of 50% or less and a starch value of 15% or more or an oil content of 5% or more.
And a method of producing a koji-mixed feed, wherein the organic waste is heated and sterilized to form a culture medium, the koji mold is mixed after the culture medium is cooled, and the koji mold is fermented by keeping the mixture in a thermostat. It is a suggestion. Under these methods and conditions, it was confirmed that a livestock feed having a high functionality and a long-term storage of 20% or less in water could be produced at low cost. In particular, a method of adjusting the water and starch value or oil content of cereal or fibrous feed to organic waste having high nutritional value is preferable,
In this way, disposal is done for a fee,
Since the organic waste which is usually disposed of by incineration or the like at a high cost can be used as a medium for Aspergillus oryzae, the production cost can be extremely reduced. If the water content of the high-concentration organic waste is 50% and the starch value is 15% or more or the oil content is 5% or more, the koji mold is grown, and the moisture is finally increased to 20% only by keeping the heat or blowing air by the fermentation heat of the koji mold. The following long-term storable livestock feed can be produced. According to another embodiment of the present invention, high-concentration organic waste is first steam-sterilized. This is to prevent the germs and the like from growing in the subsequent production process. According to another embodiment of the present invention, after the koji is mixed, the product temperature is reduced to 3%.
The fermentation of the koji is maintained at a temperature of 5 ° C. to 50 ° C. for 24 hours or more, and at the same time, the water content is reduced to 20% by weight or less. This is because the fermentation of the koji is advanced and, at the same time, the moisture of the feed finally obtained is adjusted using the heat of fermentation of the koji. According to still another embodiment of the present invention, the feed obtained by fermenting the koji mold and the organic waste are mixed. This treatment makes it possible to readjust the water content of the feed. According to a second aspect of the present invention, the feed comprises a koji-mixed feed obtained by adding and growing a koji mold to two or more feed ingredients selected from fibrous feed, cereals and organic waste. A koji-mixed feed is provided. In the above, with respect to ruminant animals, in particular, to a fibrous feed, an organic waste containing no cereal or animal protein is added, and a koji-mixed feed containing a koji-mixed feed added and grown with koji mold is provided, for example, a pig, For livestock such as chickens, add organic waste and grain or fiber feed,
Provided is a koji-mixed feed containing a feed mixed with koji to which a koji mold has been added and grown. Furthermore, it is preferable that after adding koji mold to the bran, the koji mold is grown to produce a bran koji, and the bran koji is mixed with cereals or organic waste for fermentation. Furthermore, a koji-mixed feed further comprising one or more general feeds selected from barley, rice, soybean, corn, hay, molasses, and beet pulp, in addition to the feed mixed with the koji, is provided. Here, the amount of the kneaded feed is preferably 5% by weight or more of the whole feed and / or 30% by weight or less of the whole. According to another aspect of the present invention, a high-concentration organic waste having a water content of 50% or less and a starch value of 15% or more is sterilized by heating to form a medium, and after cooling, koji mold is mixed with the medium, A livestock feed that can be stored for a long period of time and has a water content of 20% by weight or less obtained by fermenting the koji mold while keeping the temperature in a constant temperature bath is proposed. The feed is a livestock feed that has high functionality and can be stored for a long time.

[0006]

Embodiments of the present invention will be described below. In the koji mixed feed production method of the present invention, first,
Two or more feed ingredients are appropriately selected and mixed from fiber feed, cereals, and organic waste. Examples of the fibrous feed raw material include bran, wheat bran, rice bran, hay, beet pulp and the like. Examples of cereals include rice, barley, pressed pen barley, wheat, oats, rye, soybean, corn, and the like. Examples of the organic waste include those discharged from the food industry, livestock industry, fishery, household, and the like, such as juice pomace, garbage, molasses, dead fish, chicken dung, and the like. These raw materials can be arbitrarily selected by those skilled in the art according to the circumstances, such as the type of livestock to be fed, the availability of raw materials, cost, nutritional value, and the like. The selection of these feed ingredients is optional as long as the above two or more species are used. However, it is preferable that fiber feed is essential for ruminants, and organic waste is used for pigs or chickens. Is preferably used as a main raw material. At this time, the water content is preferably 50
% Or less, more preferably 25 to 40%, and can be adjusted by, for example, selection of raw materials, blending ratio, and degree of drying. Further, the starch value is preferably 15% or more or the oil content is 5% or more. In particular, a combination of a high concentration of organic waste and cereals and / or fiber feeds allows easy adjustment. Each raw material may be subjected to a pretreatment as needed so that it can be used as a feed raw material. This pretreatment is, for example, sterilization, and the sterilization may be performed by any method, but is preferably performed by temperature sterilization, particularly steam sterilization. Steam sterilization is performed, for example, at about 100 ° C. for 30 minutes.
Do about a minute.

[0007] Next, after cooling to the temperature at which the koji mold can grow, preferably 30 to 40 ° C, seed koji (the spores of the koji mold immobilized on a substrate and dried or only the spores thereof) is added.
Stir well. Examples of Aspergillus include Asp.oryzae, Asp.
awamori, Asp.sojae, preferably Asp.oryzae.kawachii,
Asp.awamori.kawachii (Kirishima Kogen Beer Co., Ltd.) and the like. The seed koji may be in the form of koji, and in the present invention,
In particular, bran koji is preferred. Of course, the seed koji may be added as it is. The amount of the seed koji to be added may be a small amount, and may be a large amount, as it grows during the production process. The amount of the seed koji with respect to the whole is, for example, 0.01 to 0.5.
%, Preferably about 0.1% of the raw material, is added as an amount of no waste. After adding the koji mold, it is preferable to further cool to 30 to 35 ° C. The cooling may be performed by any method, but is preferably performed by blowing air to supply oxygen for promoting the growth of Aspergillus. In addition, koji mold is added to one kind selected from the group consisting of fibrous feed, cereals, and organic waste as raw materials by the above-described method, and then one or more raw materials are further added to the koji mold. Mixed feeds may be produced. In a few hours after the application of the koji mold, the fever starts to occur as the koji mold grows, and the product temperature gradually rises. Thereafter, it is preferable to keep the temperature in a constant temperature bath or the like. Suitable temperature is 35 ° C-5
The temperature is 0 ° C., and cooling by blowing air or the like is effective. When the koji mold starts fermentation, moisture evaporates due to the heat of fermentation. Therefore, the feed can be made with the required moisture. Preferred water content is 30% or less, more preferably 20% or less.
For example, if the temperature is maintained at about 35 degrees to 45 degrees, about 24 degrees
Keep it warm for more than an hour to reduce the water content to about 20% or less. Also,
When the water content drops, preferably at about 20% water content, the watery fibrous feed, cereal or organic waste,
Particularly preferably, the organic waste is further added and stirred, and the fermentation can be continued by adjusting the water content to about 30%, and this can be repeated several tens of times.

[0008]

The present invention will be described in more detail with reference to the following examples. It goes without saying that the present invention is not limited to these examples. Example 1 Here, a representative example of the method for producing a koji-mixed feed of the present invention will be described below. (1) Mix 100 kg of bran and 50 kg of garbage and water 3
It was adjusted to 5% (water content is preferably 25 to 40%). (2) Steam sterilization (about 100 degrees for about 30 minutes). (3) After cooling to about 40 ° C., 100 g of seed koji was added and stirred sufficiently. (4) Cooled to about 35 degrees. (5) When 6 hours or more had passed after the application of the koji mold, heat generation began with the growth of the koji mold, and the product temperature gradually increased. (6) Thereafter, the air was cooled by blowing so that the product temperature was always within the range of 35 to 50 degrees. (7) It was completed when 40 hours or more had passed after the application of the koji mold. Forty hours after the start of koji-making, the water content was about 24%, and after 70 hours, the water content was 15 to 18%. Further, the following step was added to produce feed. (8) After 60 hours, a water content of 20%
g of the remaining rice was added and stirred to reduce the water content to about 30%. (9) The growth of the koji mold became active again, and the water content was reduced to 20% after 24 hours. (8) and (9) were repeated for two weeks.

Example 2 In addition, for comparison with the components of bran and bran koji, the components of bran koji produced by adding koji mold to the bran and then growing the koji mold, and those of general bran are shown.

[Table 1] Comparative analysis of bran and bran koji (all figures are% by weight)

The results of a more detailed component analysis are shown in Table 2.
It is.

[Table 2] Component comparison between bran koji and bran (parts other than special mention indicate ppm) As described above, bran koji only increases the protein content by about 2% as compared with conventional bran, and there is no significant difference. Regarding amino acids, bran koji also has a more predominant amino acid content in bran koji except that glutamic acid is increased. As for vitamins, the amount of vitamin B2 contained in bran koji is twice as large as that of bran.

Example 3 Next, as for the kneaded kneaded feed using the bran obtained from the above-mentioned method as a raw material for bran koji, the total weight of bran koji was 30% for energy feed such as corn, soybean, barley, hay, molasses, and beet pulp. %, And the mixture was fed to 100 cows. As a result, 1) the odor of feces was reduced, 2) the number of cows that had diarrhea for the past year was zero, and 3) the most abominable diarrhea in the early growth stage of calves that gave birth to cows that ate this diet. No remarkable results were obtained, such as 4) the shipping time was shortened by 2 to 4 months. That is, in contrast to the fact that no remarkable difference was found between the components of bran and bran koji in the component analysis of Example 2, there was a remarkable difference in the effect that appeared on livestock by blending bran with malt in the feed. Was observed. In addition, four fattening cattle were mixed with 10% bran koji of the total feed amount from the 12th month after birth, and the fattening status was observed.
580 kg body weight in daily fattening, weight gain 0.9 per day
While a 5 kg increase was observed, the weight of cattle reared on a normal feed without the addition of bran koji was 440 kg for fattening for 610 days and 0.72 kg for one day.
As is evident from the above results, the body weight has been increased by 30% or more by the feeding of bran koji. That is, when the bran koji is blended into the feed, the gain of the cow is also remarkable as compared with the case where the normal bran is blended. From these results, it can be inferred that the fattening effect of this bran using koji brassica enhances the digestive effect of enzymes rather than the nutritional value of bran koji, improves the immune resistance, and an unknown growth promoting factor presumed to be derived from koji cells. This is considered to be the effect of increasing body weight. The same effect is not necessarily limited to koji by bran,
Koji can be produced using fibrous feed such as wheat bran, rice bran, hay, beet pulp, etc. instead of bran, and feed containing this koji has a remarkable effect of raising livestock and preventing diarrhea. Furthermore, in place of fiber feed, rice, barley, pressed pen barley, wheat, oats, rye, soybeans, sorghum such as corn, juice slag, garbage, and koji using organic waste such as molasses are included. Similar effects are seen with feed.

Example 4 Black pigs were fed with the koji-mixed feed of the present invention using residual rice as a main raw material, and black pigs were fattened. Below, a black pig fed a standard feed adjusted to the stage of development, and the feed of the present invention added to the feed for 15 days.
5 shows a comparison of the average body weight of black pigs fed a% -mixed diet for about 5 months.

[Table 3] As a result, pigs fed the feed stably blended with the feed of the present invention showed better growth than the standard feed pigs.

[0013] More generally, when the weight of a black pig increases beyond 100 kg, it is said that the meat quality is high and the yield is poor. However, the black pigs fed the diet of the present invention were very excellent in meat quality because of the carcass weight. Further, no yellowing or soft fat was observed in the fat, and the appearance was beautiful. The analysis data of meat quality is shown below.

[Table 4] The black pig of the above embodiment is of the Berkshire breed, but is not limited to this, and the same effect can be obtained with ordinary pigs. In the same manner, chickens were fed with the koji of the present invention using garbage as a main ingredient. The chicken fed the normal feed weighed 4.5 kg on average in 2 months, whereas the chicken fed the diet of the present invention weighed 6 kg on average, confirming the fattening effect. In general, fattening chickens characteristically have a large amount of fat around the heart, but feeding the feed of the present invention, fattening chickens do not show this, and they are good quality chickens with little fat. Was. As a raw material for producing koji, the above-described raw materials may be used alone, or a plurality of raw materials may be mixed and used. When a raw material having a low starch content such as juice scum is used, it is preferable to use it by mixing it with a starch-rich raw material such as bran or rice bran. For Aspergillus, Asp.
oryzae, Asp.awamori, Asp.sojae, Asp.kawachii can be used. Summarizing the above test results, it is possible to mix koji as livestock feed. 1. Even if bran koji is added up to 30% of the total feeding amount, ureteral stones do not occur. 2. The odor of feces is greatly reduced. 3. Prevent diarrhea. 4. Prevent visceral disease Feeding 10% or more bran koji improves body weight gain by 20%. Livestock of good quality meat. And the like.

Example 5 Further, basic conditions for producing the koji-mixed feed of the present invention were confirmed by experiments. As a raw material of the culture medium, bran (starch value: 53.4%) and cedar sawdust (starch value: 0)
%)It was used. The bran and the sawdust were mixed, and water was added to each of them to adjust the water content to 42%. The blending ratio of bran and sawdust is 35%, 30%, 25%, 20%, 15%, and 10% of the starch value based on the total weight after moisture adjustment.
It was set to become. Next, in an autoclave 105
Sterilized for 15 minutes at ° C. After sterilizing the medium, cool it to 4
When the temperature reaches 2 ° C., 0.1% by weight of the koji mold is sufficiently mixed, cooled to 32 ° C., and kept in a constant temperature bath at 32 ° C. until the product temperature becomes 45 ° C. due to the heat of fermentation of the koji mold. The required time is shown below.

[Table 5] As is clear from the above table, when the starch value of the medium is less than 15%, the fermentation heat of the koji is scarce and the starch value required for sound fermentation of the koji is at least 15%. If the starch value of the medium is 15% or more, the fermentation of the koji mold proceeds, and at the same time, heat of fermentation is generated. This heat of fermentation can be used for removing water from the feed. Furthermore, it was found that the same effect was obtained with oil instead of starch, and the value was 5% or more. The results of this experiment show that if koji is produced from organic waste adjusted to a water content of 50% or less and a starch value of 15% or more, the water content can be suppressed to 20% or less by using fermentation heat.
As a result, it was shown that livestock feed having high functionality that can be stored for a long period of time can be produced.

Next, koji-mixed feed was produced according to various examples, and the production cost was estimated. Example 6 Production of koji-mixed feed from garbage garbage: water 75%, starch value 35% bran: water 13%, starch value 53.4% When each of them is mixed by 1 ton, water content 44% and starch value 4
It becomes 4.2%. This is steam-sterilized and cooled to 40 ° C.
1 kg of seed koji was added. After 12 hours, the temperature of the product became 45 ° C.
Maintained in the 0 ° C. range for 60 hours. As a result, the water content was 16.2.
% And a starch value of 64.5% that can be stored for a long time are 1.
24 tons were obtained. The power required for this was 40 l of 72 kW heavy oil. If the operating cost is calculated assuming 11 yen per kilowatt and 50 yen per liter of heavy oil, it would cost 2792 yen to produce 1.24 tons of koji-mixed feed. The following is a summary of expenses. All unit prices were calculated per ton for clarity. Bran purchase cost: 20,000 yen / ton Waste food collection fee: -10000 yen / ton Operating cost: 2792 yen Seed koji: 500 yen / kg Produced feed weight: 1.24 tons This produced 1.24 tons of koji mixed feed Cost is calculated as follows Cost (per 1.24 ton) = Fuma purchase cost (1 ton) +
Sliced rice collection fee + operation cost + seed koji price = 20000-100
00 + 2792 + 500 = 13292 yen Cost (per ton) = 13292 / 1.24 = 1071
9 yen This price is an epoch-making low price far below the average purchase price, considering that the average purchase price of livestock feed is between 20,000 yen and 50,000 yen. In addition, livestock feed is produced from the leftovers that cause pollution when disposed of.

Example 7 A koji-mixed feed is further produced from the koji-mixed feed and the residual rice produced in the above-mentioned Example 6. Residual rice koji: starch value 64.5%, moisture 16.2% residual rice: starch value 35%, 75% moisture, 1 ton of each, 50% starch value, 45% moisture
It becomes. This was koji-made using 1 kg of seed koji in the same manner as in Example 6 to obtain a water content of 16.8% and a starch value of 75.3%.
The utility cost required for the operation to obtain 1.2 tons of koji-mixed feed was approximately the same as in Example 6. This cost is calculated as follows: Cost (per 1.2 tons) = garbage rice koji cost + garbage collection fee + operating cost + seed koji price = 10719-10000 + 27
92 + 500 = 4011 yen Cost (per ton) = 4011 ÷ 1.2 = 3342 yen In Example 6, brass was used as a medium material (purchase cost 1
(20,000 yen per ton) and the remaining food was used.
In Example 6, since koji-mixed feed (production cost per ton of 10719 yen) was mixed with residual rice and used instead of bran, the production cost was further reduced.

Example 8 Production of a koji-mixed feed further produced from the koji-mixed feed produced in the above-mentioned Example 7 and residual rice was required for operation, except that the koji-mixed feed produced in the above-mentioned Example 7 was used. The utility costs and the like were almost the same as those in Example 6 and Example 7. The cost in this case is calculated as follows. Cost (per 1.2 tons) = Sashimi koji cost + Sashimi collection fee +
Operating cost + seed koji price = 3342-10000 + 2792
+ 500 = -3366 yen Cost (per ton) =-3366 / 1.2 = -2805 yen This result shows that while producing 1 ton of koji mixed feed, 2805
This indicates that a koji-mixed feed free of cost can be obtained, rather than a low price far beyond the common sense that a profit of yen will be made.

Example 9 1 kg of apple juice lees is added to 800 kg of apple juice lees to produce a koji-mixed feed in the same manner as in Example 6. Apple juice lees: 13% starch value, 81.6% moisture Husma: starch value 53.4%, 13% moisture Mixture: starch value 35.4%, moisture 43.4% 1.1 tons of koji mixed feed with 17.3% moisture and 50% starch value was produced from this mixture. The utility cost required for this was 2,800 yen, almost the same as in Example 6. The charge for collecting apple juice cake is 10,000 yen per ton. That is, cost = brass price + lees collection fee + utility bill + seed koji price = 2
0000-10000 + 2800 + 500 = 13300
Yen Cost per ton = 13300 / 1.1 = 12090 yen Also in this case, the purchase price of bran, the main raw material (2000)
The koji-mixed feed was completed at 1,290 yen per ton, far below 0 yen / ton).

Example 10 One ton of bran was added to one ton of dead fish to produce a koji-mixed feed similarly. Dead fish: starch value 0, moisture 51% bran: starch value 53.4%, moisture 13% 1.6 tons of koji mixed feed with 18.7% moisture, 29.9% starch value was produced from this mixture. . The utility cost required for this was 2,300 yen. The dead fish pickup fee is 15,000 yen per ton. Cost = brass price + dead fish collection fee + utility bill + seed koji price = 2000-15000 + 2300 + 500 = 78
00 yen Cost per ton = 7800 / 1.6 = 4875 yen As is clear from the above Examples 6 to 10, the cost of collecting high-concentration organic waste, which has been treated as a troublesome substance, is conventionally utilized. Not very cheap livestock feed is produced.

In comparison with the prior art, the cost reduction effect of the present invention can be analyzed as follows. First, as for feed, the conventional technology for converting high-concentration organic waste into feed has been to physically dry it. This cost can be roughly estimated by calculating the thermal energy required for the evaporation of water based on the latent heat of evaporation of the water contained in the waste. By the way, moisture 70%
The cost of drying garbage is 100 per ton only for utilities
It is more than 00 yen. About 350 kg of dry feed is produced from one ton of slag. This utility fee is a collection fee for the leftovers 1
0000 yen. That is, the total of the raw material cost and the processing cost (utility cost) required to produce 1 ton of feed is 0 yen, and the cost of the produced dried material is 0 yen. In contrast, in our technology, as shown in Examples 2 and 3, the cost is reduced with each production, and the production cost becomes negative. That is, even if the obtained koji-mixed feed is sold for free, a profit can be obtained. In addition, while the conventional technology merely dried the remaining rice, the feed according to the present technology has a koji-containing feed that is more effective than the conventional feed that improves the fattening effect of livestock. In other words, the method of the present invention provides a livestock feed that is not only less expensive than the conventional method for producing koji-containing livestock feed, but also has a lower unit price compared to a method for producing a koji-free livestock feed. Is possible. On the other hand, fertilizer is known as a method of treating organic waste, and the most common technique is fertilizer by composting. Disadvantages of this method are that it takes a long period of 6 months to make a fully-ripened compost that does not cause nitrate-nitrogen contamination in soil, the mineral content is not decomposed, and it is applicable to those with high moisture content. There are three points that cannot be done. On the other hand, the feed according to the present technology is a once-in-a-lifetime technology that includes the minerals required by livestock and eliminates the need to separately supply salt to livestock. Incineration is also used as a waste disposal method. Organic substances having a water content of 60% or less can be burned. However, when this organic substance is incinerated, a utility cost of about 5,000 yen is required to incinerate 1 ton of an organic substance having a water content of 95%. Moreover, there is no danger of dioxin being generated in some cases. This is a waste of resources because it essentially returns useful organic matter to ash.

Looking further at the livestock market, it is said that the amount of recyclable sewage is currently 7 million tons per year. In the present technology, it is possible to produce 1.4 million tons of feed from this leftovers. In addition, 6 million tons of chicken dung are generated annually. From this, about 1.2 million tons of feed can be produced in the present technology. These two fields alone can produce 2.6 million tons of feed per year. In addition, high-functional koji feed can be produced from high-concentration organic waste that has been treated as a troublesome person, such as cultured dead fish and juice pomace. In contrast, the domestic livestock feed market is 13 million tons annually. Part 95
It is said that the percentage depends on imports. If this technology is fully utilized, it is easy to improve the self-sufficiency rate of this feed by 20% or more.

As is apparent from the above description, the present technology converts organic waste, which had been previously disposed of for a fee, into koji feed that can effectively use waste charges and that is inexpensive or produces profits by itself. .
