FIG. 1 is a schematic diagram showing the configuration of an example of a poultry breeding device. FIG. 2 is a graph showing the body weight at 14 days of age in the examples.

(1) Poultry breeding method As described above, the breeding method of the present invention includes a step of alleviating the breeding inhibitory factor for poultry during the breeding period that is bred in a specific environment that is a breeding inhibitory factor. The growth inhibitory factor mitigation step includes an irradiation step of irradiating light using a light source. The light of the light irradiation is blue light.

In the present invention, the type of poultry to be bred is not particularly limited, and examples thereof include chickens, quails, turkeys, ducks, geese, etc., and chickens are preferable. The use of the poultry is not particularly limited, and examples thereof include meat, egg collection, and feathers. Further, in the present invention, the sex of the poultry is not particularly limited, and may be, for example, male or female.

In the present invention, the specific environment that causes growth inhibition is not particularly limited, and is, for example, a high temperature environment, a high humidity environment, a low temperature environment, a low humidity environment, and the like. The high temperature environment is a temperature higher than the temperature of general breeding conditions, and is, for example, an environment at a breeding temperature of 32 to 36 ° C. at the initial stage of breeding. The initial stage of breeding will be described later. The specific environment that becomes the growth inhibitory factor may be, for example, a temporary environment during the growth period, or a continuous and permanent environment.

The wavelength of the blue light is, for example, 435 to 480 nm, preferably 440 to 460 nm. The blue light may include any wavelength, and may include other wavelengths and the like.

The illuminance of the blue light is, for example, 5 lux to 100 lux, preferably 5 lux to 60 lux. In the irradiation of the blue light, for example, the illuminance may be changed stepwise, and specifically, the illuminance may be lowered over time. The decrease in illuminance may be, for example, a gradual decrease or a continuous decrease. Of the period of irradiating the blue light in the growing period, for example, the first half and the second half may have different illuminances. In this case, for example, the illuminance of the blue light to be irradiated in the first half and the illuminance of the blue light to be irradiated in the second half may be a ratio of 1: 0.05 to 1: 0.9. In the initial stage of breeding, for example, the first half is during the 1-week age, and the latter half is during the 2-week age.

The light source is not particularly limited as long as it is a light source capable of irradiating blue light. As the light source, for example, an LED (light emission diode) or the like can be used. A light irradiation device provided with the light source can be used for irradiating poultry with the blue light.

In the irradiation step, the environment for irradiating poultry with the blue light is not particularly limited, and is, for example, indoors such as a poultry house. The irradiation of the blue light indoors can be said to be, for example, the irradiation of the blue light in an environment in which external light such as sunlight is not substantially irradiated. Further, in the irradiation step, for example, the blue light may be irradiated by blocking light other than the blue light.

In the breeding method of the present invention, the irradiation step may be applied to poultry during the breeding period, and the stage of the breeding period is not particularly limited. The breeding conditions at stages other than the breeding period are not particularly limited. The stages of the breeding period include, for example, stages such as an early stage of breeding, a middle stage of breeding, and a late stage of breeding. In the present invention, the "early stage of breeding" is a period from 0 days to 14 days, with the day of chicks being 0 days. In the present invention, the "mid-growth period" is a period from 15 days to 35 days. Further, in the present invention, for example, after the growing period, the same blue light may be further irradiated.

In the growing period, the number of days to irradiate the blue light is not particularly limited, the lower limit of the number of days is, for example, one day or more, and the upper limit of the number of days is, for example, 15 days or less. Moreover, it is preferable that the irradiation of the blue light is performed every day during the growing period. Specifically, when the growing period is the initial stage of growing, it is preferable that, for example, the irradiation of the blue light is performed every day from 0 days to 14 days of age.

The irradiation of the blue light may be performed from the beginning to the end of each stage of the growing period, or may be performed during a predetermined period of each stage of the growing period, for example.

In the growing period, the lower limit of the total irradiation time of the blue light per day is, for example, 18 hours or more, and the upper limit is, for example, 24 hours or less.

The irradiation of the blue light during the growing period may be performed intermittently, for example. The irradiation period for irradiating the blue light may be, for example, between 17:00 and 6:00 am, and the blue light may be non-irradiated for a total of more than 0 hours and 6 hours or less.

In the present invention, the growing conditions after the growing period are not limited in any way, and for example, conventional conditions can be adopted.

(2) Poultry Constitution Control Method The poultry constitution control method of the present invention comprises an irradiation step of irradiating poultry during the breeding period with light using a light source, and a poultry breeding area. It includes a temperature control step of controlling the temperature. The light of the light irradiation is blue light. In the present invention, the above-mentioned description of the growing method of the present invention can be incorporated for the irradiation of the blue light.

In the present invention, the "constitution" is not particularly limited, and includes, for example, body weight, physique, flesh (muscle, abundant fat, etc.), blood components, and the like.

The temperature control process controls so that the preset temperature becomes constant. The preset temperature is, for example, an arbitrary temperature within the range of 19 ° C. to 33 ° C. The normal temperature is a temperature similar to the temperature of general breeding conditions, for example, a temperature of 27 to 31 ° C. at the initial stage of breeding, and the high temperature is higher than the temperature of general breeding conditions. It is a high temperature, for example, a temperature of 32 to 36 ° C. at the initial stage of growing. In the temperature control step, for example, the temperature is controlled by using an air conditioner such as a fan or an air conditioner, a heating device such as a heater, a cooling device, or an automatic window opening / closing device. Further, in the temperature control step, for example, in addition to the above-mentioned devices, a worker (a keeper or the like) may manually open and close the window to control the temperature.

The constitution control method of the present invention may further include, for example, a temperature measurement step. The temperature measuring step is a step of measuring the temperature in the breeding area. The breeding area is not particularly limited, and is, for example, a cage, a hut, or the like in which poultry in the poultry house is housed. The temperature may be measured continuously to monitor the temperature in the breeding area, or intermittently (for example, every 1 hour, every 6 hours, etc.) to monitor the breeding area. The temperature inside may be monitored.

The constitution control method of the present invention is a pattern (also referred to as pattern 1) in which the blue light is irradiated in the irradiation step and the temperature is controlled to be normal in the temperature control step, in the irradiation step. A pattern (also referred to as pattern 2) that irradiates the blue light and controls the temperature to be high in the temperature control step, and does not irradiate the blue light in the irradiation step and controls the temperature. In the step, a pattern for controlling the temperature to be normal (also referred to as pattern 3), and in the irradiation step, the blue light is not irradiated, and in the temperature control step, the temperature is set to a high temperature. At least one of the four patterns (also referred to as pattern 4) is used to control changes in the constitution of the poultry. Specifically, for example, it is preferable to use the pattern 1 when increasing the weight of the poultry, and to use the pattern 4 when decreasing the weight of the poultry.

Patterns 1 and 3 for controlling the temperature to be normal may be changed over time, for example. When the temperature is changed, for example, the temperature may be lowered by a predetermined temperature every predetermined number of days. The predetermined number of days is, for example, 1 to 3 days, and the predetermined temperature is, for example, 1 to 2 ° C. per the predetermined number of days.

Patterns 2 and 4 for controlling the temperature to be high may, for example, change the temperature over time. When the temperature is changed, for example, it may be lowered to a predetermined temperature according to a predetermined number of days. The predetermined number of days is, for example, 1 to 3 days, and the predetermined temperature is, for example, 1 to 2 ° C. per the predetermined number of days.

Patterns 1 to 4 may be performed, for example, from the beginning to the end of each stage of the growing period, or may be performed during a predetermined period of each stage of the growing period.

The patterns 1 to 4 may be switched to each other according to, for example, the stage of the breeding period of the poultry, the shipping time, and the like. Specifically, for example, when it is desired to accelerate the initial stage of growing or the shipping time, the pattern 3 may be switched to the pattern 1. On the other hand, if it is not the initial stage of growing or if it is desired to delay the shipping time, the pattern 1 may be switched to the pattern 3. It should be noted that this is an example, and each pattern can be switched between each other.

In the case where the temperature measuring step is included, for example, when the measured temperature is equal to or higher than a preset temperature or lower than or equal to a preset temperature, the constitution control method of the present invention is at least one of the patterns 1 to 4. One may be carried out automatically. The temperature is not particularly limited and can be set arbitrarily.

In the breeding method of the present invention, the irradiation step and the temperature control step may be applied to poultry during the breeding period, and the stage of the breeding period is not particularly limited. The breeding conditions at stages other than the breeding period are not particularly limited. The stage of the growing period is, for example, the same as described above. Further, in the present invention, for example, after the breeding period, at least one of the patterns 1 to 4 may be used for breeding.

In the growing period, the number of days for carrying out the patterns 1 to 4 is not particularly limited, the lower limit number of days is, for example, 0 days or more, and the upper limit number of days is, for example, 15 days or less. Moreover, it is preferable that at least one of the patterns 1 to 4 is carried out every day during the growing period. Specifically, when the growing period is the initial stage of growing, for example, it is preferable that the pattern 1 is performed every day from 0 days to 14 days. On the other hand, when the growing period is other than the initial stage of growing, for example, it is preferable that any one of the patterns 1 to 4 is carried out every day during the age of 15 days or later.

In the growing period, the lower limit of the total temperature control time per day is, for example, 180 hours or more, and the upper limit is, for example, 24 hours or less, preferably 20 hours.

The irradiation of the blue light in patterns 1 and 2 may be performed intermittently, for example. The irradiation period for irradiating the blue light may be, for example, between 17:00 and 6:00 am, and the blue light may be non-irradiated for a total of more than 0 hours and 6 hours or less.

During the breeding period, the breeding conditions other than the blue light irradiation and the temperature are not particularly limited, and general conditions can be adopted. Further, in the present invention, the growing conditions after the growing period are not limited in any way, and for example, conventional conditions can be adopted.

(3) Poultry breeding device The poultry breeding device 10 of the present invention includes a light source unit 20, an air conditioning unit 30, and a control unit 40. FIG. 1 shows the configuration of an example of the poultry breeding apparatus 10 of the present invention. It is preferable that the apparatus 10 can block light from the outside such as sunlight by means of, for example, a plate or a curtain. The term "outside" means, for example, outside the device 10 or outside the breeding area.

The light source unit 20 includes a blue light source that emits blue light. In the present invention, the blue light can be referred to the above-mentioned description of the growing method of the present invention.

As the blue light source, for example, an LED (light emission diode) or the like can be used.

In the present device 10, for example, as the light source unit 20, a lighting device including a blue light source that emits blue light and a lighting device including a light source that emits light of another color (for example, a white light source that emits white light) are independent of each other. May exist. Further, the apparatus 10 includes, for example, a light source unit 20 including the blue light source and a light source that emits light of the other color, and the emitted light can be switched between blue light and light of the other color. It may be.

The air conditioning unit 30 executes air conditioning in the breeding area. The breeding area is, for example, the same as described above. The air conditioning is not particularly limited, and may be performed, for example, to warm the breeding area or maintain a high temperature. Further, the air conditioning may be performed, for example, to cool the breeding area or maintain a low temperature. Further, the air conditioning may be performed, for example, to maintain the breeding area at a normal temperature. The high temperature is, for example, 32 to 36 ° C. in the initial stage of breeding, and the low temperature is a temperature lower than the temperature of general breeding conditions, for example, 20 to 26 ° C. in the initial stage of breeding. The normal temperature is, for example, 27 to 31 ° C. at the initial stage of growing, as described above. As the air conditioner unit 30, for example, an air conditioner such as a fan or an air conditioner, a heating device such as a heater, a cooling device, an automatic opening / closing device for windows, or the like can be used. Further, in addition to the air conditioning unit 30, for example, a worker (breeder or the like) may manually open and close the window to perform air conditioning in the breeding area.

The control unit 40 controls the light irradiation by the blue light source and the air conditioning based on preset conditions. The control unit 40, the light source unit 20, and the air conditioning unit 30 may be able to communicate with each other via, for example, a communication network (not shown). As a result, the control unit 40 outputs, for example, a light irradiation signal instructing light irradiation, an air conditioning signal instructing air conditioning, and the like to the light source unit 20 and the air conditioning unit 30. That is, the poultry existing in the breeding area is affected by the light irradiation by the light source unit 20 (blue light, white light, etc.) and the air conditioning by the air conditioning unit 30.

The communication network is not particularly limited, and a known network can be used. For example, it may be wired or wireless. Examples of the communication line network include an Internet line, WWW (World Wide Web), a telephone line, LAN (Local Area Network), SAN (Storage Area Network), DTN (Delay Tolerant Networking), and the like. Examples of wireless communication include WiFi (Wireless Fidelity) and Bluetooth (registered trademark). The wireless communication may be either a form in which each device directly communicates (Ad Hoc communication) or an indirect communication via an access point. The device 10 may be connectable to an external device (external database, printer, storage device, image pickup device, etc.) via the communication network.

The control unit 40 may be controlled so as to change the illuminance of the light irradiation stepwise, for example, or specifically, the illuminance may be lowered with time. The decrease in illuminance may be, for example, a gradual decrease or a continuous decrease. Further, the control unit 40 may control, for example, to change the air conditioning stepwise, and specifically, the temperature in the breeding area may be raised or lowered over time. The temperature rise or fall may be continuous or gradual, for example.

The control unit 40 may execute the control of the light irradiation and the air conditioning based on the accommodation date when the 0-day-old poultry is housed in the breeding area, for example. Specifically, for example, the blue light is irradiated from the containment date for one week, the inside of the breeding area is controlled to be normal, and the blue color is set for two weeks from the containment date. Controls such as controlling the inside of the breeding area to a high temperature without irradiating with light may be performed. It should be noted that this is an example, and the present invention is not limited to this. When the light irradiation by the blue light is not performed, for example, the light irradiation by the light of another color (white or the like) may be performed, or the light from the outside such as sunlight may be irradiated.

The preset conditions are not particularly limited. When the preset condition is, for example, a temperature condition in the breeding area, the apparatus 10 may further include a measuring unit. The measuring unit measures the temperature in the breeding area. In this case, the control unit 40 may control to switch to light irradiation by the blue light source when the temperature is equal to or higher than a preset temperature. As can be seen from the results of the examples described later, poultry grow at a slower rate in a high temperature environment. Therefore, according to the present device 10, when the temperature in the breeding region is high, the delay in the breeding speed of poultry can be alleviated by irradiating the blue light.

When the preset condition is, for example, breeding data, the apparatus 10 may further include a storage unit. The storage unit accumulates and stores breeding data. The breeding data is not particularly limited, and is, for example, information on poultry in captivity such as body weight and number of deaths, and information on breeding areas such as temperature and humidity. The breeding data may be acquired by, for example, the apparatus 10 via the communication network, or by inputting the respective information via an input device (keyboard, touch panel, etc.). You may. In this case, the control unit 40 may control the light irradiation by the light source unit 20 and the air conditioning by the air conditioning unit 30 based on the breeding data.

The control unit 40 can use, for example, a central arithmetic unit (central processing unit) such as a CPU or GPU.

(4) Poultry production method The poultry production method of the present invention is at least one of (1) a poultry breeding method, (2) a poultry constitution control method, and (3) a poultry breeding apparatus. Includes raising poultry using one.

As poultry, male and female chickens (broilers, breeds: chunky) were used.

An experimental area (breeding box) partitioned by 700 cm in length × 400 cm in width × 600 cm in height was prepared indoors. Then, a bar unit type LED light was arranged in the experimental section. The LED light is equipped with an LED element for blue light and is dimmable at 0% -100%. The wavelength peak of blue light was 450 nm. The number of LED lights per experimental plot was one (1 unit). The LED light was installed in the center of the experimental plot at a height of 600 mm from the floor surface.

On the other hand, a weight loss of 30.8% was confirmed. Further, as shown in FIG. 2 (B), it was confirmed that the weight loss of Comparative Example 2-2 (female) was 22.8% as compared with that of Comparative Example 2-1 (female) in the female as well as in the male. Was done. From this, it was found that the high temperature environment is a factor that inhibits the growth of chickens in both males and females. On the other hand, as shown in FIG. 2 (A), Example 1-2 (male) irradiated with blue light in a high temperature environment is Example 1-1 (male) irradiated with blue light in a normal temperature environment. However, a weight loss of 23.6% was confirmed. Further, as shown in FIG. 2 (B), a weight loss of 17.4% was confirmed in Example 2-2 (female) as compared with Example 2-1 (female). From these results, it was found that the growth-inhibiting factor can be alleviated by irradiating both males and females with blue light in a high-temperature environment that is a growth-inhibiting factor. Furthermore, by irradiating blue light in a high temperature environment, a significantly higher growth promoting effect was obtained as compared with a normal temperature environment.
