Chicken breeding method using LED {A METHOD FOR BREEDING CHICKEN USING LED}

The present invention relates to a chicken breeding method.

The breeding targets of chickens are divided into broilers for the purpose of using the chicken itself for food and laying hens for the purpose of using the egg for food.

On the other hand, the chicken is a habit of ingesting the feed only when the bright light can be used as a means of controlling feed intake.

With regard to the breeding of chickens using the above lighting, the purpose of lighting in laying hens and broilers is fundamentally different. The lighting of the laying system is an example of a hormone involved in spawning in harmony with the photoperiod of the living body, and is intended to increase the laying rate by stimulating the secretion of testosterone. On the other hand, broiler lighting is to feed a lot of feed, to increase the weight gain rate of broilers. The algae use behavioral habits to feed only during bright hours, and lighting in broilers is a powerful tool that can absolutely control broiler feed intake.

In general, end point lighting is used in broiler farms in Korea to maximize feed intake, digestion and absorption. The night lighting method is mainly used in Korean broiler farms. Although the simplest and most convenient, there is a problem of high mortality, abnormal conductors, and high abdominal fat accumulation due to sudden death syndrome (SDS).

In order to improve the problems of the end point lighting method, an intermittent lighting method or an incremental lighting method has been provided.

The intermittent lighting method is a lighting method that repeats the day and night several times a day, there are a number of names according to the contrast cycle, 1L: 3D method to darken one hour to three hours is typical, but its use is insufficient. This is because it is difficult to turn on or turn off the fire at a certain time by manpower every day, and the installation cost is burdened when the brightness is controlled through a dimmer, which is a mechanical device.

The incremental lighting method is intended to achieve the same weight as other lighting methods in order to produce a balanced growth between the skeleton, organs, and muscle tissues in the early stages of natural sunshine conditions, and gradually increase the lighting time to induce compensatory growth. Means the way.

The compensation growth is a phenomenon in which growth is temporarily suppressed and then accelerated, that is, a rate of increase of the increase in incremental light bulb is increased after a certain time, and a rate of increase of SDS is increased. Mortality is improved and feed demand is also improved.

However, there is a problem that it is difficult to illuminate or turn off the fire of the house at a certain time, such as the intermittent lighting method, by personnel every day, and the feeder and the water supply should be sufficiently installed so that the house does not run out of water. There are many problems. If the flocks are not able to feed enough during the bright season, there is also a problem that the uniformity of the flocks may be reduced and compensation growth may be insufficient to reduce the allowance weight. There is also a limitation that chicken is shipped before compensatory growth occurs.

Meanwhile, fluorescent lamps and incandescent lamps are mainly used as the type of light bulbs used in the conventional lighting method. In general, chickens, especially broilers are not known to see a distinct productivity difference according to the wavelength of the light, unlike the laying hens, many people use fluorescent lamps in order to save electricity. In addition, in the case of brightness, it is recommended that it is not too bright because too bright the development is suppressed and carnibalism tends to occur, and the reason for initially brightening is for the chick to easily determine the position of the bucket and the feed container, The reason for darkening in the latter days is to reduce the occurrence and unnecessary stress of carnival pecking other chickens.

In order to solve the problems of the prior art as described above, an object of the present invention is to provide a breeding method having a higher breeding efficiency, a lower mortality rate, and a higher scattering rate and a higher breeding rate when the existing lighting method is used.

In order to achieve the above object, the present invention provides a chicken breeding method for performing the lighting method using the LED light.

The inventors of the present invention, while studying the relationship between lighting and chicken breeding efficiency, in particular the relationship between the spawning rate and growth rate, and the lighting and mortality rate, unlike the fluorescent or incandescent lamps that are used in the existing lighting method, the breeding efficiency is high. It was confirmed that the remarkably improved and the mortality is lowered, and furthermore, in the case of adjusting the type of LED lighting, that is, the wavelength band and the degree of illuminance of the light, it is confirmed that the breeding efficiency is significantly improved compared to other conditions. Completed.

Hereinafter, the present invention will be described in more detail.

The present invention relates to a chicken breeding method using the LED light. More specifically, the present invention provides a chicken breeding method for performing the lighting method using the LED light.

In the present invention, the lighting method refers to a method of raising chickens while irradiating light to a certain condition inside a cage or lighting a predetermined condition.

The present invention is a chicken breeding method using the LED light. In the case of replacing the type of lighting, that is, the light source or bulb type with LED from the incandescent or fluorescent lamps used for the breeding of chickens, it was confirmed that the breeding efficiency of the chickens increased significantly and mortality decreased.

In the breeding method of the present invention, using a LED light for irradiating light in the wavelength range of 450nm to 690nm, irradiating or raising the chicken's breeding ground for 13 to 22 hours in a day at 0.1 W / m ² to 0.5 W / m ² illuminance It relates to a breeding method of chickens, characterized in that the breeding of chickens under irradiation conditions.

More specifically, the conditions of the present invention may vary depending on the type of chicken.

In the case of broilers of broilers for the purpose of improving the rate of increase of chickens, it is preferable to use LED lighting that irradiates light in the wavelength range of 450 nm to 590 nm.

More specifically, in the broiler breeding method using the lighting method, the present invention can use LED lighting for irradiating light in the wavelength range of 450nm to 590nm.

For example, the present invention is a light irradiation for chicken breeding for 15 to 22 hours of the day at a light intensity of 0.1 W / m ² to 0.5 W / m ² using an LED light for irradiating light in the wavelength range of 450nm to 590nm It may be a broiler breeding method, characterized in that the chickens are raised under the irradiation conditions. The LED light may be an LED light that emits yellow light, preferably an LED light that emits yellow light in a wavelength range of 540 nm to 580 nm, and the illuminance may be 0.15 W / m ² to 0.3 W / m ² . In other words, the time to investigate the name may be 18 hours to 21 hours.

Under the above conditions, an increase of about 11% was confirmed as compared with the case of using a fluorescent lamp used as a light source or a light bulb, and a reduction in mortality of about 6% was confirmed based on the case of using a fluorescent lamp. In the case of using the same LED, the increase in the scattering rate of about 9% and the decrease in mortality of about 4% were observed in the case of using the yellow light compared to the red light.

In addition, since the broiler body weight gain is excellent from the 7th or 14th day of breeding, which is the early stage of breeding, the mortality rate is lowered, but the weight gain rate of the broiler is low until compensatory growth occurs. As it can be supplemented, it is expected that the effect will be better when used in the incremental lighting method.

In addition, in the case of breeding a laying hen for the purpose of improving the egg laying rate of a chicken, it is preferable to use LED illumination which irradiates the light of 530 nm-690 nm wavelength band.

More specifically, in the breeding method of the laying hen using the lighting method, the present invention can use a yellow light instead of the red light that is known to help the scattering, in particular, to use the LED light to irradiate light in the wavelength range of 530nm to 690nm Can be.

For example, the present invention is a light irradiation for chicken breeding for 13 to 19 hours of the day at a light intensity of 0.1 W / m ² to 0.5 W / m ² using an LED light for irradiating light in the wavelength range of 530nm to 690nm It may be a breeding method of a laying hen, characterized in that the breeding of chickens under the irradiation conditions of.

The LED light may be an LED light that emits yellow light, preferably an LED light that emits yellow light in a wavelength range of 540 nm to 580 nm, and the illuminance may be 0.15 W / m ² to 0.3 W / m ² . In other words, the time to investigate the name may be 14 hours to 18 hours.

In the above conditions, the secretion of testosterone was increased by about 8% compared to the case of using a fluorescent lamp used as a light source or a light bulb, and egg production, or egg production rate, was increased by about 5%. The demand was also increased, and even when the same LED was used, there was an increase in the scattering rate of about 6% and an increase in the release of male hormones by about 20% compared to the case of using the 880nm red light. It became.

The breeding method of the present invention can reduce the mortality which is a problem of the chicken breeding method by the conventional lighting method, and the weight and feed efficiency of broiler broiler compared to the fluorescent light or other wavelength LED lighting used in the existing lighting method In addition, since the egg production of laying hens can be increased, it can be applied to various industrial fields related to birds including chickens in that the raising efficiency of chickens including both laying hens and broilers can be improved.
