Description

Technical Field

[0001] The present invention relates to a pig repellent, a pig repellent method, a pig repellent container, and a pig repellent manufacturing method for preventing pigs from entering farmland, various facilities, and the like.

Background Art

[0002] In recent years, as a result of the sharp increase in the capture of wild boars in mid-mountainous regions from the outskirts of plains to mountainous areas, the activity area of wild boars has not only remained in farmlands but has also expanded to urban areas. Such an expansion of the habitat range of wild boars has brought about various problems such as damage to crops in farmlands, harm to humans (bites, parasites, etc.), and damage to earth structures such as levees, embankments, and fills. In particular, harmful behaviors such as wild boars turning over the ground in order to prey on plant roots, insects, and larvae have been increasing. Such damage caused by wild boars has not only spread to mid-mountainous regions but also to golf courses and natural parks, and furthermore, the risk of intrusion into housing complexes, schools, and the like has been expanding.

[0003] For this reason, various measures for preventing the intrusion of wild boars have been conventionally devised. For example, those that prevent the intrusion of wild boars by enclosing the protected area with a metal fence, a synthetic resin net, or the like (see, for example, Patent Documents 1 and 2) are known. Also, a pest repellent (see, for example, Patent Document 3) that repels wild boars and the like with a peculiar odor is known. This pest repellent is a repellent composed of a concentrated liquid of cereal vinegar, fruit vinegar, rice vinegar, or rice black vinegar with a concentration of 20% to 50%. By placing this pest repellent within a range where pests may appear, it prevents the intrusion of pests.

[0005] However, when installing metal fences or nets as described in Patent Documents 1 and 2, the equipment must be strong enough to withstand damage from wild boars, and it must also be installed over a wide area. As a result, not only is the installation cost and labor enormous, but the ongoing costs are also high due to the need to check for damage to the metal fences or nets and to repair them. Furthermore, even when metal fences or nets are installed, there are increasing cases where farmers are forced to give up farming because they are unable to prevent wild boar intrusion and their fields are ravaged.

[0006] Furthermore, the pest repellent described in Patent Document 3 prevents the intrusion of wild boars and other animals by using odors from grain vinegar or fruit vinegar, but there is a risk that wild boars may become accustomed to the odors of grain vinegar or fruit vinegar, reducing the repellent effect.

[0007] On the other hand, in sheltered workshops, because the types of work that people with disabilities can perform are limited, work is often contracted out for extremely low wages. In fact, some people with disabilities are not even paid the minimum wage set by the local government, leading to social problems such as great anxiety about the future for the guardians of people with disabilities.

[0008] Therefore, the present invention aims to provide a wild boar repellent, a wild boar repellent method, a wild boar repellent container, and a wild boar repellent manufacturing method that can repel wild boars more effectively at a lower cost, in order to solve the above problems. [Means for solving the problem]

[0009] To solve the above problems, the invention of claim 1 is a boar repellent characterized in that it uses at least one of deer excrement, deer body components, and parasites that parasitize deer as deer odor-generating substances, and emits a deer odor from said deer odor-generating substances.

[0010] The invention of claim 2 is characterized in that, in the boar repellent described in claim 1, the deer odor generating substance is impregnated into a liquid and formed into a liquid state.

[0011] The invention of claim 3 is characterized in that, in the boar repellent described in claim 1, the deer odor-generating substance is mixed with fertilizer and formed into a solid.

[0012] The invention of claim 4 is a method for repelling wild boars, characterized by laying the wild boar repellent described in any one of claims 1 to 3 in at least one of the place where it is desired to prevent wild boar intrusion and its surrounding area.

[0013] The invention of claim 5 is a wild boar repellent container characterized by comprising a container body that contains the wild boar repellent described in any one of claims 1 to 3 and releases odor from the wild boar repellent, and mounting means that allows the container body to be attached to an external member.

[0014] The invention of claim 6 is characterized in that, in the wild boar repellent described in claim 1, the deer odor-generating substance is adsorbed onto a porous material containing charcoal and seaweed.

[0015] The invention of claim 7 is characterized in that, in the boar repellent described in claim 1, pressurization is performed after depressurization in order to adsorb the deer odor-generating substances onto a porous material containing charcoal and seaweed in the liquid.

[0016] The invention of claim 8 is a method for producing the boar repellent described in claim 1, characterized in that the deer odor-generating substance is melted at room temperature under high pressure, and the raw solution is diluted with a liquid containing water.

[0017] The invention of claim 9 is a method for producing the boar repellent described in claim 8, wherein the ratio of the liquid containing water to the stock solution is increased by adding a predetermined amount of alcohol. It is characterized by the following: [Effects of the Invention]

[0018] The inventors of this invention have discovered and confirmed that wild boars dislike deer. Specifically, deer generally do not have the habit of mud bathing (although some males in heat rub mud on their necks), and many ticks parasitize their bodies. On the other hand, wild boars dislike tick infestations and have the habit of mud bathing frequently, and the number of ticks parasitizing them is significantly less than that of deer. Furthermore, the inventors have confirmed that, for example, if wild boars dig up the ground and then new grass shoots appear, causing deer to come, the wild boars will change their habitat and leave the area to avoid tick infestations. They have also confirmed that wild boars have an excellent sense of smell comparable to that of dogs, and are able to distinguish even the less odorous feces and urine of deer, and that they physiologically dislike and avoid the smell of deer and their feces and urine, and that this repellent effect lasts for a long period of time (they do not become accustomed to the smell).

[0019] Furthermore, according to the invention described in claim 1, the boar repellent is composed of deer odor-emitting substances and emits the odor of deer that boars physiologically dislike, making it possible to effectively and continuously repel boars. Moreover, since deer excrement, deer body components, and parasites that infest deer are used as deer odor-emitting substances, it is possible to easily produce the boar repellent at low cost. For this reason, it is possible to produce and manufacture the boar repellent as part of a labor-intensive work project.

[0020] Furthermore, since deer are herbivores, their droppings contain plant-derived flavonoids and other substances with deodorizing effects. In addition, because deer ruminate, their droppings contain little undigested organic matter. For these reasons, even if a boar repellent made from deer droppings is scattered on farmland or golf courses, the odor can be minimized, and the impact on humans is minimal. Moreover, in terms of hygiene, excellent organic disinfection technologies have been developed in recent years as a countermeasure against COVID-19 and other diseases, making it possible to handle them safely.

[0021] According to the invention described in claim 2, since the pig repellent is formed in a liquid state, it can be easily and properly applied and laid in a wide range of arbitrary locations by spraying, atomizing, or applying the pig repellent to the location where pig intrusion is to be prevented and its surroundings. For example, it can be easily and properly applied not only to the ground such as farmland and golf courses but also to building walls, utility poles, etc.

[0022] According to the invention described in claim 3, since the pig repellent is formed in a solid state, it can be easily and properly applied to a wide range of arbitrary locations by spreading or placing the pig repellent at the location where pig intrusion is to be prevented and its surroundings. Moreover, because it is in a solid state, handling, storage, transportation, etc. become easy. Also, since a deer odor generating substance and fertilizer are mixed to form the pig repellent, it is possible to use the pig repellent as fertilizer. That is, by spreading it on farmland, golf courses, etc., it is possible to give fertilizer and at the same time repel pigs.

[0023] According to the invention described in claim 4, since it is only necessary to lay the pig repellent at the location where pig intrusion is to be prevented and its surroundings, it is possible to easily and at low cost repel pigs.

[0024] According to the invention described in claim 5, by housing the pig repellent in the container body and attaching the container body to an external member with the attachment means, the odor from the pig repellent in the container body can be released to the outside, preventing pigs from approaching the surroundings. That is, since there is no need to directly scatter the pig repellent in the protected area and its surroundings, roads, etc., the protected area and its surroundings can be maintained in their original state, and it is also possible to respond quickly and easily even when temporarily wanting to repel pigs. Furthermore, it is only necessary to carry the container body containing the pig repellent to the location where pig intrusion is to be prevented or attach it to an external member, and there is no need to directly handle the pig repellent by hand, so it is more hygienic and easy to handle.

[0025] According to the inventions described in claims 6 to 8, since the handling of the pig repellent becomes easy, it is possible to commercialize it and place it on the sales route.

[0026] According to the invention described in claim 9, even when it is difficult to obtain or the amount of wild deer droppings and urine used as raw materials for wild boar repellents is insufficient, it is possible to manufacture a wild boar repellent with a high wild boar repellent effect. [Brief explanation of the drawing]

[0027] [Figure 1] This figure shows the state after the boar repellent according to Embodiment 1 of this invention has been sprayed. [Figure 2] This document shows a plan view (a) of a boar repellent container according to Embodiment 2 of the present invention, a side view (b) thereof, and a side view (c) showing the container with the lid open. [Modes for carrying out the invention]

[0028] The present invention will be described below based on the illustrated embodiments.

[0029] (Embodiment 1) Figure 1 shows the state after the boar repellent 1 according to this embodiment has been scattered. This boar repellent 1 is a repellent for preventing boars M from entering protected areas 101 such as farmland, golf courses, and various facilities. In this embodiment, the boar repellent 1 is laid (placed) directly within or around the protected area 101 to deter boars M.

[0030] This boar repellent 1 uses at least one of the following as a deer odor-generating substance: deer excrement, deer body components, and parasites that infest deer. This substance emits a deer odor. Here, deer excrement includes deer feces, urine, and saliva; body components include deer meat, hair, hide, and hooves; and parasites that infest deer include ticks, lice, and fleas. One or more of these substances—deer excrement, body components, and parasites—are used as the deer odor-generating substance, and boar repellent 1 is produced from this substance, emitting a deer odor.

[0031] In this embodiment, depending on the target protected area 101 and the surrounding environment, the system includes both a liquid form of boar repellent 1 and a solid form of boar repellent 1. First, the liquid form of boar repellent 1 is formed by impregnating deer odor-generating material with a liquid. That is, deer odor-generating material such as deer feces and urine is impregnated with a liquid such as water, hot water, or enzyme water, and extracted into a liquid state that satisfies environmental hygiene standards.

[0032] Furthermore, the solid boar repellent 1 is formed by mixing deer odor-generating materials with fertilizer. In other words, deer odor-generating materials such as deer droppings and urine are mixed with livestock manure, humus, food waste, and other waste / fertilizers to make them usable as fertilizer, and are formed into solid or granular (granular) form while satisfying environmental hygiene standards.

[0033] Next, a method for preventing wild boars from entering using such a wild boar repellent 1 will be explained. The wild boar repellent 1 should be laid in at least one of the areas where you want to prevent wild boars M from entering (protected area 101) and its surroundings. That is, depending on the target protected area 101 and the surrounding environment, you can choose to use either a liquid or solid wild boar repellent 1, and then lay the wild boar repellent 1 directly within or around the protected area 101.

[0034] For example, if the protected area 101 is farmland or a golf course that requires fertilizer, a solid boar repellent 1 that can be used as fertilizer is laid over the entire area of ​​the farmland or golf course. On the other hand, if the protected area 101 is a school or building and it is undesirable to spoil its appearance or it is not possible to lay the repellent directly within the protected area 101, a liquid boar repellent 1 is laid around the school or building. In this case, the liquid boar repellent 1 may also be laid on the walls of the school or building or around utility poles. Laying methods include spraying, scattering, scattering, arranging, and burying, and the laying method should be changed according to the protected area 101 and the surrounding environment.

[0035] As described above, this boar repellent 1 and boar repellent method make it possible to effectively and continuously repel boars M because the boar repellent 1 is composed of deer odor-generating substances and emits a deer odor that boars M physiologically dislike. Furthermore, since it is only necessary to lay the boar repellent 1 in or around the area where you want to prevent boar M from entering, it is possible to repel boars M easily and at low cost. Moreover, since deer excrement, deer body components, and parasites that infest deer are used as deer odor-generating substances, it is possible to easily produce the boar repellent 1 at low cost. For this reason, it is possible to produce and manufacture the boar repellent 1 as part of a workforce.

[0036] Furthermore, since deer are herbivores, their droppings contain plant-derived flavonoids and other substances with deodorizing effects. In addition, because deer ruminate, their droppings contain little undigested organic matter. For these reasons, even if a boar repellent made from deer droppings is scattered on farmland or golf courses, the odor can be minimized, and the impact on humans is minimal. Moreover, in terms of hygiene, excellent organic disinfection technologies have been developed in recent years as a countermeasure against COVID-19 and other diseases, making it possible to handle the material safely.

[0037] Furthermore, if the boar repellent 1 is in liquid form, it can be easily and effectively applied to a wide range of locations by scattering, spraying, or coating the boar repellent 1 in or around areas where boar M intrusion needs to be prevented. For example, it can be easily and effectively applied not only to the ground in farmland and golf courses, but also to building walls and utility poles.

[0038] Furthermore, if the boar repellent 1 is in solid form, it can be easily and effectively applied to a wide range of locations by scattering or placing it in areas where boar M intrusion needs to be prevented or in the surrounding areas. Moreover, because it is solid, it is easy to handle, store, and transport. In addition, since the boar repellent 1 is formed by mixing deer odor-generating material and fertilizer, and can be used as fertilizer, it is possible to repel boar M at the same time as providing fertilizer by scattering it on farmland, golf courses, etc.

[0039] Incidentally, in waste management businesses dealing with livestock manure, humus, and food waste, there has traditionally been a situation where fertilizer produced as a by-product of processing was not sold, and excellent waste treatment technology was not utilized. However, by mixing such fertilizer with deer odor-generating material to produce boar repellent 1, waste treatment technology and fertilizer can be effectively utilized. Furthermore, while fertilizer produced from livestock manure and food waste is highly regarded as organic fertilizer, boars M have a strong palatability to its faint odor (putrefaction odor), resulting in frequent damage from digging by boars M after fertilization, and many farmers were forced to use inorganic fertilizer. However, by using boar repellent 1, which is produced by mixing organic fertilizer with deer odor-generating material, it becomes possible to repel boars M while applying organic fertilizer to farmland and practice organic farming.

[0040] (Embodiment 2) Figure 2 shows a plan view (a) of the boar repellent container 2 according to this embodiment, a side view (b) thereof, and a side view (c) showing the lid 32 in the open position. This boar repellent container 2 contains the boar repellent 1 from Embodiment 1 and is attached to an external member to prevent boars M from approaching the surrounding area.

[0041] This boar repellent container 2 mainly comprises a container body 3 and a hook (mounting means) 4. The container body 3 is a container that holds the boar repellent 1 and releases the odor from the boar repellent 1 to the outside. In this embodiment, it is a thin, roughly rectangular box shape, with a lower storage section 31 and an upper lid section 32 connected by a hinge 3a on the back edge, and this hinge 3a allows the lid section 32 to open and close relative to the storage section 31. The size of the storage section 31 is set to accommodate a predetermined amount of boar repellent 1.

[0042] Furthermore, multiple elongated ventilation holes 32a extending horizontally and with overhangs to prevent rainwater from entering are formed vertically on the front and back surfaces of the lid 32, allowing odors from the boar repellent 1 inside the storage section 31 to be released to the outside through these ventilation holes 32a. In addition, a locking piece 32b extending toward the storage section 31 is provided at the center of the lower end of the front surface of the lid 32, and a locking pin 31a is provided at the center of the upper end of the front surface of the storage section 31. By inserting and locking the locking pin 31a into the locking hole formed in the locking piece 32b, the upper opening of the storage section 31 is closed by the lid 32, as shown in Figure 2(a). By releasing the lock, the lid 32 opens, as shown in Figure 2(c), allowing the boar repellent 1 to be inserted into and removed from the upper opening of the storage section 31.

[0043] The hook 4 allows the container body 3 to be attached to an external member. In this embodiment, it is an inverted J-shaped rod and is provided on the upper part of the lid 32. Specifically, the vertical part 41 extends from the upper surface of the lid 32, and the free end of the arc part 42 curves toward the lid 32. The hook 4 is also rotatably connected to the upper part of the lid 32 around the vertical part 41 as an axis. The container body 3 can then be attached to an external member such as a fence, railing, or building component by hooking the hook 4 onto the external member.

[0044] According to this embodiment, by storing the boar repellent 1 in the container body 3 and attaching the container body 3 to an external member with a hook 4, the odor from the boar repellent 1 inside the container body 3 is released to the outside through the ventilation hole 32a, preventing boars M from approaching the surrounding area. In other words, since there is no need to directly scatter the boar repellent 1 in the protected area 101 or its surroundings, roads, etc., the protected area 101 and its surroundings can be maintained in their original state, and it is also possible to respond quickly and easily when it is necessary to temporarily deter boars M. Furthermore, since the container body 3 containing the boar repellent 1 can be carried to the place where it is necessary to prevent boars M from entering or attached to an external member, there is no need to directly handle the boar repellent 1 by hand, making it more hygienic and easier to handle.

[0045] Although embodiments of this invention have been described in detail above, the specific configuration is not limited to these embodiments, and any design changes, etc., that do not depart from the gist of this invention are also included. For example, in Embodiment 2 described above, the hook 4, which is the mounting means, is integrally provided with the container body 3, but it may also be a separate mounting means from the container body 3. For example, the mounting means may be made of a belt, a belt loop may be provided on the back of the container body 3, and the container body 3 may be attached to the external member by passing the belt through the belt loop and tying the belt to the external member.

[0046] Furthermore, when commercializing and selling wild boar repellents, the wild boar repellent may be constructed by adsorbing deer odor-generating substances onto a porous material containing charcoal and seaweed, or by applying pressure after depressurization to adsorb deer odor-generating substances onto a porous material containing charcoal and seaweed in a liquid. In addition, as a method for manufacturing wild boar repellents, deer odor-generating substances may be melted at room temperature under high pressure, and the resulting concentrate may be diluted with water or other liquid.

[0047] Incidentally, when we continued our research into the mechanism by which wild boars avoid the smell of deer feces and urine, we found that wild deer feces and urine contain undigested cellulose, the main component of the grass and bark that the deer eat, and microorganisms that can break down cellulose into glucose (cellulose-degrading bacteria). As the decomposition (fermentation) of cellulose progresses, alcohol is produced, and the smell is a mixture of putrid odor and alcohol odor. Therefore, we have found that the smell that wild boars avoid may include the smell of alcohol.

[0048] Based on this finding, in the method for producing the boar repellent, the ratio of the water-containing liquid to the stock solution (dilution ratio) may be increased by adding a predetermined amount of alcohol. This makes it possible to produce the boar repellent while preventing a decrease in boar repellent effect, even when it is difficult to obtain or the amount of wild deer droppings and urine used as raw materials for the boar repellent is insufficient. Here, the predetermined amount is about 1 / 10 of the deer odor-generating material, and when alcohol is added, the dilution ratio can be increased to about 10 times. Furthermore, it is also conceivable to use alcohol as an artificial deer odor-generating material instead of the deer odor-generating material as a boar repellent. For example, when using a boar repellent produced by mixing deer odor-generating material with organic fertilizer for organic farming, it is conceivable to use a polymer-based or porous adsorbent, silicon dioxide (silica gel), or calcined mica that has adsorbed alcohol instead of the deer odor-generating material.
