Description

  The present invention relates to an additive for feed used for poultry such as chickens, turkeys and quails, or livestock such as cattle, pigs and sheep.

  Conventional feed for poultry, for example, production of cereals such as corn and milo, edible oil cakes such as soybean oil cake, bran such as bran, rice bran, barley distilers solubles, corn gluten meal, starch cake, soy sauce cake, etc. A mixture of feed ingredients such as moss, meat and bone meal, fish meal, blood meal, feather meal, animal fats and other animal feed materials, or feed additives such as minerals, vitamins, amino acids and antibacterial agents. Those prepared by addition are often used.

  In general, some feed materials for poultry feed are expensive, and there are nutrients that are not enough with feed materials alone. In many cases, they are used to supplement or even provide medicinal properties. Feed additives are also used, but this feed additive is also costly and eventually feed is expensive. Therefore, in order to reduce the cost of feed, it is required to reduce the cost of feed materials and improve the nutritional value or medicinal efficacy of feed materials. If this demand can be achieved by using industrial waste, the problem of effective use of industrial waste can be solved.

  Examples of the industrial waste include seafood residues. The seafood residue is produced, for example, in a fishery processing plant that processes seafood into dried fish, canned foods, etc. For example, fish shells such as saury and sardines, shells of salmon, sea urchins, oysters, etc. after egg collection. Can be mentioned. In particular, disposal of salmon after egg collection has become a problem in recent years. Such pupae after egg collection are produced in the process of producing salmon roe, and are generally called hochare. The salmon roe is collected from the river that has gone up the river, and its abdomen is torn with a knife. Although salmon roe is shipped for commercial use, salmon after egg collection has a very low fat content in the body and its commercial value as fish meat is low, so most of it is disposed of as industrial waste. In recent years, the aquaculture business has been on track, and the amount of salmon after egg collection that occurs when producing salmon roe has increased. Therefore, effective utilization of the salmon after egg collection has been desired.

  In addition, there exists an example like (patent document 1) as a prior art regarding the cocoon after egg collection. (Patent Document 1) proposes an edible emulsion mainly composed of rice cake. In the detailed explanation, “The salmon that goes up to the river and lays eggs is called a“ hotchare ”. It is used for fertilizer, feed, etc. Used as an agent ... "(left column on page 2, lines 28-32), but the amount used is only a small part of the amount discarded. Moreover, about the utilization to a fertilizer and feed, it only touches on availability, and the proposal about the concrete component and preparation means is not made at all. Therefore, it has been desired to develop a specific means for effectively using the sputum after egg collection and using the sputum after egg collection as an additive for feed.

JP-A-5-161476

  In view of the above-described conventional situation, the object of the present invention is to use industrial waste such as salmon after egg collection, which has high nutritional value, has various medicinal effects, is inexpensive, and is a conventional expensive feed material. Another object of the present invention is to provide an additive for feed that can be replaced with an additive for feed and can reduce the cost of the feed.

That is, this invention provides the following feed additive in order to achieve the said objective.
(1) Feed additive characterized by containing a shell and plum vinegar.
(2) The feed additive according to (1), wherein the feed additive contains tea shells in addition to shells and plum vinegar.
(3) The feed additive as described in (1) or (2) above, which further contains seaweeds.
(4) The feed additive as described in (3) above, wherein the seaweed is an unused part produced in the process of processing the seaweed.

(6) In addition to the feed additive according to any one of (1) to (5) above, the feed additive characterized by containing at least one selected from ume charcoal, krill and soybean meal .

  The kombu temporary root, tea shell, ume vinegar and ume charcoal used in the feed additive of the present invention are not conventionally used in feed, and the feed additive of the present invention is unique in that they are used in feed. It is a thing. Thus, all of these kombu temporary roots, tea husks, ume vinegar and ume charcoal, as described in detail later, each have a unique and excellent nutritional value or medicinal effect, and are so-called industrial wastes and are inexpensive. . The shell used in the present invention is also industrial waste and is inexpensive. Furthermore, seaweeds such as kelp used in the present invention are rich in minerals, vitamins and the like and have excellent nutritional value, and some of them have been disposed of as industrial waste in the process of processing. Furthermore, the salmon after egg collection used in the present invention also contains highly nutritious proteins, and most of them are conventionally disposed of as industrial waste. Therefore, it can be used at low cost. Therefore, by using the feed additive of the present invention, it is possible to impart excellent nutritional value or medicinal effect to the feed, and to reduce the amount of conventional expensive feed raw materials or feed additives used. Cost can be reduced. At the same time, the problem of effective use of industrial waste can be solved.

  According to the present invention, using industrial waste, it has high nutritional value, has various medicinal effects, is inexpensive, and can be replaced with a conventional expensive feed material or feed additive. A feed additive capable of reducing cost is provided. The feed additive of the present invention can be applied to both poultry and livestock, but is preferably applicable to poultry and mid-chicken.

It is a figure of kelp.

Hereinafter, the present invention will be described in detail.
The temporary root of the kelp used in the present invention is the next part of the kelp. That is, as shown in FIG. 1, the kelp 1 is composed of three parts: a leaf-like part 10 that is normally eaten, a stem-like part (petiform) 11, and a temporary root (root part) 12 of kelp. And the temporary root 12 of this kombu is a part which plays the role which fixes the kelp 1 whole to a rock etc., and absorption of a nutrient is not performed like the root of a plant on land. The temporary root 12 of kelp contains about twice as much mineral as the leaf-like portion 10, and is rich in potassium. Moreover, polysaccharides such as alginic acid, fucoidan, and cellulose, and dietary fiber are contained about 1.7 times as much as the leaf-shaped portion 10, which is a nutritionally excellent part. In addition, animal experiments have shown that it is anti-tumor and has an action of suppressing the growth of cancer cells, and is particularly effective for suppressing breast cancer cells. And most of the temporary roots 12 of this kelp are disposed of as industrial waste during the production of edible kelp.

  If this kombu temporary root 12 is added to the feed, the nutritional value of the feed is improved by the abundant nutrients, and characteristics such as antitumor properties can be effectively utilized. That is, in general, antibiotics are added to conventional feeds to maintain the health of poultry and livestock, but when humans eat poultry and livestock grown on the feeds, the antibiotics are allergic to humans. It has been pointed out that this may be the cause. If the kombu temporary root 12 is added instead of the antibiotic added to the feed, the health of poultry and livestock can be maintained, and there is a possibility that allergic problems of humans eating poultry and livestock can be solved. Moreover, the temporary root 12 of this kelp is industrial waste as described above and is inexpensive, and its use is nothing but effective use of industrial waste.

  The entire root 12 of the kelp can be used, but among them, it is preferable to use the portion 122 excluding the branch portion 121 close to the stem portion 11. In kelp aquaculture, a rope is poured into a fishing ground, and spores are grown on the rope so that the kelp hangs down from the rope. At that time, the branching part 121 is an old root, as shown in FIG. It was found that it was most likely to rot because it settled on the rope 2 and became entangled. Therefore, the use of the temporary roots of kelp can be further promoted by removing this branching part 121. The branching part 121 to be removed can be distinguished because it tends to be darker than other parts.

  The temporary root 12 of kelp can be used alone as a feed additive, or can be mixed with other blending components and used as a feed additive. Examples of other ingredients include at least one selected from tea shells, shells, and plum vinegar, and various seaweeds other than the above-described temporary roots of kelp. Furthermore, at least one selected from ume charcoal, krill and soybean oil cake is also preferably used. It is also possible to use blending components other than the blending components listed here. In the case of using a mixture of the kombu temporary root 12 and other blending components, the mixing ratio can be appropriately set according to the type and number of blending components used.

  In addition, as the kelp 1 from which the above-described temporary roots 12 of kombu are collected, any kelp that is generally edible, such as the genus Kombu, the genus Torokonbu, the Nekoushikonbu, can be applied. Specific species names include macomb, resilive, hidakambu, rousecomb, onicomb, hosomecomb, honeycomb, and Nagacomb.

  In addition to the above-described temporary roots of kelp, seaweeds can be appropriately blended with the feed additive of the present invention, or together with shells, ume vinegar, tea shells and the like described later. As seaweeds, in addition to the above-mentioned various kelps, green algae such as Aonori (Usba aonori, Bow Aonori, Susioonori, Hira Aonori), Aosa (Aanaosa, Ribbon Aosa), Human egusa, Mill, Iwauta, Chlorella, Dunaliera, etc. , Hijiki, matsumo, havanori, wakame, mekabu, alame, kajime, hondawala, etc. Red seaweeds such as rice bran, egonori, oxenori, proboscis, ogonoris, tsunotama, funori, macri, hanagiagi, cedar, gonogori, suizendinori, ashitsukiki, ichikurage, hasai (hair vegetables), imidori (seafood) The Mention may be made of a blue-green algae such as Rurina.

  When blending seaweeds, the entire portion can be used, but in particular, unused portions such as chips generated in the process of processing seaweeds are preferably used. Conventionally, when processing seaweeds such as kelp and seaweed, the harvested seaweeds are appropriately cut according to the product, so that there is a problem that a large amount of chips are generated. For example, in the case of kelp, a large amount of chips are produced when processing into various products such as kelp rolls. In addition, the cultivated wakame had its stems and leaf tips removed at the time of shipment, but the removal amounted to about 20% of the whole harvested wakame, and the total weight reached several thousand tons per year. In spite of the fact that these chips are equivalent or better in terms of nutritional value compared to the product parts, they were discarded as they were. By this invention, the unused part which consists of these chips can be utilized effectively.

  As a suitable example of the non-use part, as shown in FIG. 1, a tip part 101 of the leaf-like part 10 of the kelp 1 can be exemplified. The tip portion 101 is often cut off as an unnecessary portion with no commercial value when processing the harvested kelp, and is discarded as it is. According to the present invention, the unnecessary tip portion 101 can be effectively used at low cost. In addition, although the length of the front-end | tip part 101 made unnecessary changes with aspects of the processing of kelp, generally it is about several to 40% of the leaf-shaped part 10 whole.

  Subsequently, various tea husks are applicable as the tea husks used in the present invention, but green tea husks are preferably used. There are various types of green tea, such as gyokuro, sencha, and bancha. These types can be used without question, and all so-called Japanese tea can be used. Note that the tea husk is a residue after extracting tea components as a beverage or the like.

  In recent years, various soft drinks have been sold in large numbers at convenience stores, supermarkets, vending machines, etc., and a large proportion of green tea drinks are included therein. In the production of green tea beverages for sale, a large amount of tea husks are generated and disposed of as industrial waste.

  Green tea components such as catechins, caffeine, vitamin C, and theanine remain in the tea husk, and anticancer, antioxidant, antiviral, cholesterol-reducing effects in blood, immune response enhancement, etc. There is. Therefore, if the tea husk is added to the feed, the component is added to the feed and the action it has is imparted. Moreover, this tea husk is industrial waste as described above and is inexpensive, and its use is nothing but effective use of industrial waste.

  The tea husk is mixed with the above-described kelp temporary root, other seaweeds, or shells and ume vinegar, and used as an additive for feed. It may be mixed with ingredients other than the kombu temporary root, other seaweeds, shells and plum vinegar. The mixing ratio of the tea husks in the feed additive can be appropriately set according to the type and number of blending components used for mixing.

  Next, various shells can be used as the shell used in the present invention, and among them, a scallop shell is particularly preferably used. The main component of the shell is calcium carbonate, which is used as a calcium source for poultry and livestock. Shells are industrial wastes in the fishery processing industry, and some of them are used as roadbed materials, concrete materials, etc., but most of them are discarded. Therefore, shells are inexpensive, and using them is an effective use of industrial waste.

  The shell is mixed with the above-described temporary root of kelp, other seaweeds, or ume vinegar, and used as a feed additive. It may be mixed with ingredients other than kombu roots, other seaweeds, and plum vinegar. When shellfish is used in combination with ume vinegar, a unique effect is obtained as described later. The mixing ratio of the shells in the feed additive can be appropriately set according to the type and number of compounding components used for mixing.

  The ume vinegar used in the present invention is a by-product of the production of umeboshi. That is, umeboshi is generally produced by salting raw ume with a salt of about 15 to 20% by weight of the raw ume, and a large amount of ume vinegar is produced as a by-product. Some of this ume vinegar is used for the production of plum juice obtained by desalting ginger pickles, shiso pickles, vinegar pickles, and ume vinegar by ion exchange membrane electrodialysis, but most of them are industrial waste. As a disposal.

  Ume vinegar contains salt, organic acids such as citric acid, malic acid and tartaric acid, carbohydrates such as glucose, fructose and sucrose, amino acids such as serine, alanine and aspartic acid, and also has bactericidal and antiseptic properties. There are effects. Therefore, when ume vinegar is added to the feed, the components are added to the feed, and its bactericidal action, antiseptic action, and the like are imparted. The preservability of feed is improved by the bactericidal action and antiseptic action of ume vinegar. In particular, the above-described kombu roots and other seaweeds are likely to rot (in the case of kombu temporary roots, it starts to rot at room temperature for about 2 hours), so it was difficult to use in the past, but combined with plum vinegar This makes it possible to preserve abundant nutrients effectively. In general, cattle and other livestock have traditionally been licked with salt, such as rock salt, to compensate for the lack of minerals, but ume vinegar originally contains salt, which is effective for mineral supplementation. It is. Moreover, this ume vinegar is industrial waste as described above and is inexpensive, and its use is nothing but effective use of industrial waste. In addition, you may add ume vinegar after diluting as needed or concentrating.

  By using this ume vinegar in combination with the above-mentioned shells, the citric acid of ume vinegar and the calcium of shells can react to produce calcium citrate. Since calcium citrate is easily absorbed by the body, it becomes more effective for calcium supplementation for poultry and livestock.

  Plum vinegar is used as an additive for feed by mixing with the above-described temporary roots of kelp, other seaweeds, or shells. It may be mixed with ingredients other than kombu roots, other seaweeds, and shells. The mixing ratio of ume vinegar in the feed additive can be appropriately set according to the type and number of blending components used.

  The ume charcoal used in the present invention is produced by carbonizing raw materials derived from ume. The raw materials derived from this plum include pruned plum branches, plum seeds discharged during the processing of plum fruits, plum dried seeds discharged during processing of plum pickles, and when cutting plum trees Examples include plum tree parts such as branches, trunks and roots. At present, none of these raw materials derived from plums are used effectively and are disposed of as industrial waste. Carbonization of the raw material resulting from plum can be easily performed in accordance with known charcoal production.

  Plum charcoal has an excellent adsorptive power and has the effect of adjusting the stomach and intestines of poultry and livestock. In addition, ume charcoal, which is carbonized from the umeboshi seeds discharged during the processing of umeboshi, contains salt from the beginning, and if this ume charcoal is added to the feed, it is effective in supplementing minerals in poultry and livestock. . And the raw material of this ume charcoal is industrial waste as above-mentioned, and it is cheap, and using ume charcoal is nothing but effective use of industrial waste.

  Plum charcoal is used as an additive for feed by mixing with the above-described temporary roots of kelp, other seaweeds, shells and ume vinegar. It may be mixed with ingredients other than the kombu temporary root, other seaweeds, shells and plum vinegar. The mixing ratio of ume charcoal in the feed additive can be set as appropriate according to the type and number of blending components used.

  As the krill used in the present invention, various krills can be widely used without regard to the type. Krill is inexpensive because it is abundant in resources and available in large quantities. Krill is rich in nutrients such as vitamins, EPA, and DHA. Krill also has the effect of increasing the market value by making the egg yolk yellow. If krill is added to the feed, its nutrients are added to the feed.

  Krill is used as an additive for feed by mixing with the above-described temporary roots of kelp, other seaweeds, or shells and ume vinegar. Mixing ingredients other than kombu temporary roots, shells and plum vinegar may be mixed. The mixing ratio of krill in the feed additive can be set as appropriate according to the type and number of blending components used.

  The soybean oil cake used in the present invention is a residue after squeezing oil from soybeans, is a high-protein one, and has been conventionally used in feed. The reason why soybean oil cake is used in the present invention is to stabilize the form of the feed additive of the present invention in a powder state, or to make it easy to mix each component, in addition to utilizing the nutritional value of the high protein. It also has the purpose of functioning as a binder.

  Soybean oil koji is used as an additive for feed by mixing with the above-described kombu temporary root, other seaweeds, or shellfish and ume vinegar. It may be mixed with ingredients other than the kombu temporary root, other seaweeds, shells and plum vinegar. The mixing ratio of soybean oil cake in the feed additive can be appropriately set from the viewpoint of allowing the soybean oil cake to function as a binder.

  Furthermore, a fish and shellfish residue can also be mix | blended with the feed additive of this invention. The term “seafood residue” as used herein refers to ara parts such as saury and sardines, shells such as sea urchins and oysters. Moreover, when mix | blending, ara parts, such as saury and sardines, are dried and mix | blended with a powder. Also, shells of sea urchin, oysters, etc. are blended in powder form. Most of such seafood residues are disposed of as industrial waste during marine processing, and according to the present invention, the seafood residues can be used effectively.

  The above-mentioned ara portion such as saury and sardines contains various nutrients. For example, parts such as the head and skin contain lipids, amino acids, DHA and the like, and bone parts contain calcium. In this way, if a fish arab that contains various nutrients is added to the feed, the abundant nutrients are added to the feed.

  Shells such as oysters and sea urchins can be used as a calcium source for poultry and livestock because the main component is calcium carbonate. When these shells are used in combination with ume vinegar, calcium citrate is produced by the reaction of citric acid of ume vinegar with calcium of shellfish. Since this calcium citrate is easily absorbed by the body, it becomes more effective for calcium supplementation of poultry and livestock.

  The seafood residue as described above is mixed with the above-described kombu root, other seaweeds, ume vinegar or the like and used as an additive for feed. The mixing ratio of the seafood residue contained in the feed additive can be set according to the type and time of the livestock.

  Furthermore, in this invention, the salmon after egg collection can be employ | adopted suitably as said seafood residue. In the case of blending, the eggplant after egg collection is blended as a powder after drying. Most of such eggs after egg collection are disposed of as industrial waste. Therefore, it is inexpensive and its use is nothing but effective use of industrial waste.

  The dried powder of salmon after egg collection contains components such as collagen, DHA, EPA, and vitamin D, and has cell activation, calcium and phosphorus intestinal absorption promotion, and the like. It also contains highly nutritious proteins and is a good protein source. If the dried powder of salmon after egg collection is added to the feed, its components are added to the feed, and the action it has is imparted to livestock such as cattle.

  Generally, livestock such as cattle has a problem of lack of minerals. In order to make up for the shortage of minerals, the salt content of rock salt has been licked in the past, but it was necessary to prepare rock salt separately. Since the dried powder of salmon after egg collection is derived from the sea, it contains salt. Therefore, an additive for feed containing dried powder of salmon after egg collection is effective and convenient because it can replenish minerals at the same time as providing various nutrients as described above.

  In addition, since the sputum after egg collection tends to rot easily, the utilization was conventionally difficult. About this, in this invention, it can preserve | save especially by combining with ume vinegar. Plum vinegar contains organic acids such as citric acid, malic acid, and tartaric acid, and thus has bactericidal and antiseptic effects. Thereby, deterioration of the cocoon after egg collection can be prevented, and the abundant nutrients inherent to the cocoon can be used effectively. Moreover, the citric acid of plum vinegar reacts with the calcium of the salmon after egg collection to produce calcium citrate. Since this calcium citrate is easily absorbed into the body, it becomes more effective for calcium supplementation in poultry and livestock.

  Moreover, what carbonized the eggplant after egg collection can also be mixed with the feed additive. The charred rice cake helps the intestinal good bacteria such as lactic acid bacteria to grow and activates the function. Thereby, digestive absorption of the gastrointestinal tract of poultry and livestock is promoted.

  There are various methods for drying salmon after egg collection used in the present invention, such as a method of drying with warm air and a method using a dehydrating sheet. For example, one preferred drying method uses the following Joule heat. First, a caged egg wrapped in an insulating net is fixed between electrodes. Next, a current is applied to the cage after egg collection using a constant current device. Initially, current easily flows due to moisture and sodium chloride contained in the cage after egg collection. Moisture is evaporated and dried by Joule heat generated by passing an electric current. As moisture decreases, it becomes difficult for current to flow, but a constant current can be passed by increasing the voltage. Further, as the drying progresses, the volume of the bag decreases, but the bag can be fixed between the electrodes by various methods such as moving the electrodes or moving the support base. In this method, Joule heat is generated in the body of the cocoon by the current flow, and the Joule heat is directly used for evaporation of moisture. Therefore, compared with the method of drying with warm air, the salmon after egg collection can be efficiently dried. Moreover, carbonization of soot can be performed using an apparatus similar to the above. By filling the carbon powder with the soot between the electrodes and passing an electric current through the electrodes, the temperature between the electrodes rises to nearly 1500 ° C., and the soot can be carbonized.

  The eggs after egg collection dried by the drying method described above are then powdered. There are various methods for pulverizing the dried cocoon after egg collection, such as a method of pulverizing using a crusher and a pulverizer.

  The dried powder of salmon after egg collection as described above is mixed with the above-described temporary roots of kelp, or shells and ume vinegar, and used as a feed additive. The mixing ratio of the dried powder of salmon after egg collection contained in the feed additive can be set according to the type and timing of livestock.

  EXAMPLES Hereinafter, although an Example and a comparative example demonstrate this invention further more concretely, it is not limited to these.

(Examples 1-4, Comparative Example 1)
First, powdery feed additives having various compositions as shown in Table 1 were prepared.
Each feed additive obtained was added to the reference feed to prepare a feed.

A chicken breeding test was conducted using the standard feed and each feed obtained. That is, using 500 chickens, divided into 5 sections of 100 chickens, one section giving only the reference sample as a comparison section, and the other four sections giving each obtained feed as a test section, Breed for 5 weeks.
As a result, the average weight gain rate of the chickens in the test group was higher than that of the comparative group, and the feed amount and feed cost per bird were also superior to the comparative group.

(Examples 5 and 6, Comparative Example 2)
First, 1 kg of salmon after egg collection was wrapped in an insulating net and fixed between electrodes placed in parallel. Next, using a constant current device, a current of 100 A was passed between the electrodes for 20 minutes. As a result, moisture was evaporated by Joule heat, and soot was dried. The upper electrode was lowered by the weight in accordance with the volume reduction of the soot accompanying drying. As a result, the bag remains in contact with both electrodes until it is dried. Next, the dried eggs after egg collection were pulverized using a crusher and a crusher. The obtained dried powder of salmon after egg collection was added so as to have a composition as shown in (Table 2) to prepare a feed additive for powder. Each feed additive obtained was added to the reference feed to prepare a feed.

  Rats were reared using the standard feed and the resulting feed. That is, using 21 rats, 7 rats were divided into 3 groups, and one group was given only a reference sample as a comparison group (Comparative Example 2), and the other two groups were used as test groups. Each of the feeds obtained in 6 was fed and reared for 5 weeks. As a result, the rats in each test group had an average weight gain rate that exceeded that of the comparative group. Further, as shown in (Table 3), the rats in the test group of Example 6 had calcium and magnesium values in the femur exceeding those of Example 5. This is considered to be an effect obtained by adding a combination of dried cocoon powder and ume vinegar after egg collection.
