Definitions
- the present invention relates to an animal and plant breeding facility, an animal and plant bred using the same, an activated gas generating device, a method of producing an animal and plant, and an animal and plant bred by the method.
- Animal and plant breeding facilities are used in various fields. Specifically, in the case of animals, there are places such as a zoo, an insect garden, a botanical garden, a poultry farm, a pig farm, a cowshed, a milking farm, a ranch, an aquarium, a pet shop, and a farm.
- the facilities used in these places are formed by surrounding the four sides with metal structures made of rods, meshes, or plates, and animals are kept in their internal space (breeding room). Things.
- places such as farms and mushroom farms are mentioned, and the facilities used in these places are greenhouses using fats such as vinyl alcohol.
- the first viewpoint is that it is necessary to consider the effect on animals and plants.
- Inadequate hygiene controls can lead to flora and fauna becoming infected with viruses and vehicle bacteria, airborne bacteria, and allergen components that float in the room.
- flora and fauna becoming infected with viruses and vehicle bacteria, airborne bacteria, and allergen components that float in the room.
- the cost damage will be enormous.
- infected animals must take appropriate measures, for example, by incinerating all chickens and pigs in their poultry farms and pig farms, resulting in a large cost loss.
- the second viewpoint is that it is necessary to consider the effects on humans involved in animal and plant breeding facilities. If the hygiene management in the animal and plant breeding facilities is not sufficient, humans engaged in the breeding of animals and plants in the facility or who are observing the animals and plants in the animal and plant breeding facilities for ornamental use However, there is a possibility that it will be infected with viruses, fungi, and bacteria that float in the facility space, and allergen components. In addition, there is also a problem that human beings may feel extremely uncomfortable due to body odor from animals and plants and odor such as feces. Furthermore, the air in the internal space where the animals and plants are present leaks to the external space, and it is avoided because it drifts as odor.
- the third viewpoint is that it is necessary to consider the effect on the local environment where the breeding facilities are installed.
- odors that local people find unpleasant may be released.
- viruses and plant-borne viruses, viable bacteria, airborne bacteria, and allergen components may be released to the local environment where breeding facilities are installed. Insufficient hygiene control in animal and plant breeding facilities may affect unrelated environments around the facilities.

- ozone when a gas containing ozone is used as the activation gas, it is necessary to consider the harmfulness of ozone itself. In other words, a very small amount of ozone is effective for disinfection and inactivation of viruses, mold fungi, airborne bacteria, and allergen components, and for deodorization of odor components. Become. If the ozone concentration is high, irritation to the respiratory system, eyes, mucous membranes, etc., may have a large adverse effect on the human body. The allowable value of ozone concentration varies depending on the laws and regulations of each country.For example, in Japan, the value of photochemical dioxin (a general term for ozone and other substances containing oxidizing substances as main components) is one hour as an environmental standard for air pollution.
- ozone has a peculiar pungent odor, and has the disadvantage of being unpleasant.

- the breeding facility 101 shown in FIG. 12 can of course be used for breeding animals and plants.
- the breeding facility 101 is particularly suitable for breeding facilities for animals, such as experimental animals such as rats and mice, from which virus infection should be completely eliminated.
- the breeding facility 101 includes a box-shaped breeding room 103 in which animals and plants are housed, an air introduction duct 104 and an air exhaust duct 105 connected to an opening formed in the breeding room 103, and a breeding room 103.
- a breeding basket 106 for fractionation and accommodation for each individual or a plurality of individuals, a blast from the air introduction duct 104, a bulky wind tunnel 107 for collecting animals and plants in the breeding cage 106, and the wind And an ion generating element 108 provided at the tip of the cavity 107.
- the breeding room 103 preferably has a sealable structure such as a glass plate in order to completely shut out infections such as viruses.
- the breeding basket 106 is made of, but not limited to, a net-like metal material.
- an openable / closable window 109 is formed so that the breeder 110 can care for rats such as feeding and water supply. It is most preferable that the opening / closing window 109 has a function of blocking the flow of air between the inside and the outside of the breeding room 103.However, in order to facilitate feeding, etc., a part of air such as a grid or a net is not provided. A part that can diffuse may be provided. Even in that case, as will be described later, since a forced air flow is formed from the air introduction duct 104 to the air exhaust duct 105, the air passes through the inside and outside of the breeding room 103 through the opening / closing window 109. It is possible to control and reduce the infection such as virus.
- the installation locations at the ends of the air introduction duct 104 and the air exhaust duct 105 opposite to the side connected to the breeding room 103 are to introduce air from outside the breeding room 103 and to install the air outside the breeding room 103, respectively. It is not particularly limited as long as the air can be exhausted to the outside, but it is preferable to communicate with an air purifier capable of removing viruses in order to prevent infection of animals and plants in the breeding room 103 with viruses and the like. .
- the air introduction duct 104 and the air exhaust duct 105 need to be provided with a blowing means in order to form an airflow in which the force on the air introduction duct 104 also flows toward the air exhaust duct 105. It is desirable to provide it in
- the air outside the breeding room 103 is sucked in from the air introduction duct 104 by the blowing means, and the air passes through the wind tunnel 107 and enters the breeding basket 106 together with the ions generated by the ion generating element 108. And finally discharged out of the rearing room 3 through the air exhaust duct 105.
- the opening / closing window 10 is provided. 9 reduces the exchange of air between the inside and outside of the breeding room 103, and can prevent viruses and the like from reaching the rat 102 and the human without being inactivated by each other. It is possible to reduce the possibility of mutual disease transmission between rats.
- the following experiment was performed using the breeding facility 101 having the above configuration.
- clean air equivalent to 15 ventilations / hour is blown into the breeding room 103 from the air introduction duct 104 and discharged from the air exhaust duct 105.
- Air containing positive and negative ions is supplied from the ion generating element 108 and supplied to the living area of the rat 102 to reduce the concentration of viruses and the like released from the rat 102.
- ions were released using the same ion generating element 108 as that described in the first embodiment, and the positive and negative ion concentrations in the breeding cage 106 were reduced to 20,000 those with ZCM 3 or 3, 000 pieces / cm 3, no ion release (positive and negative ion concentration of about 50 ZCM 3) in three conditions, were kept in conditions completely isolated from each other.
- the conditions other than ion generation are the same, including air blowing.
- the ozone concentration in the breeding room 103 was less than O.Olppm.
- Figure 13 shows the average change in body weight for males and females under each condition.
- Fig. 13 shows the results for female and
- Fig. 14 shows the results for female.
