Embodiment approach
[0035] [constitute]
[0036] First, the configuration of the lighting system according to the embodiment will be described. figure 1 The outline of the lighting system according to the embodiment is shown. figure 2 It is a block diagram showing the functional configuration of the lighting system according to the embodiment.
[0037] Such as figure 1 As shown, the lighting system 10 according to the embodiment is a lighting system for raising diurnal poultry, and more specifically, the lighting system 10 is a lighting system for raising chickens. The lighting system 10 is installed in the chicken coop 60, for example. Such as figure 1 as well as figure 2 As shown, the lighting system 10 includes a lighting device 20 and a control device 30 . Each device will be described in detail below.
[0038] [lighting device]
[0039] First, the lighting device 20 will be described in detail. The lighting device 20 is installed on the ceiling of the chicken house 60 and illumina...
Embodiment 1
[0056] The inventors found that, during the raising period of chickens, irradiating the rearing area 70 with light having a peak emission wavelength of 560 nm to 590 nm can promote weight gain of chickens. Hereinafter, Examples 1 to 3, and Comparative Examples 1 and 2 will be described in detail using the lighting system 10 . Figure 8 It is a schematic diagram showing light emission control according to the first embodiment.
[0057] exist Figure 8 , and the vertical axis represents light intensity (p.d.u.). In addition, the light intensity is an example of an index showing the brightness of the light source unit 22 . 1 (p.d.u.) is the light intensity equivalent to 1 lx (lux) of an incandescent lamp in the eyes of a chicken. exist Figure 8 In , the horizontal axis shows the growing period (day).
[0058] First, the growing period will be described. The breeding period of meat-eating chickens such as broilers is generally about 49 days. In an embodiment, the period of...
Embodiment 2
[0070] Next, light emission control according to Embodiment 2 will be described. Figure 9 It is a schematic diagram showing light emission control according to the second embodiment.
[0071] In Example 2, the early growing period is divided into two periods of the first period T21 and the second period T22 following the first period T21. The first period T21 is, for example, a 9-day period from the 0th day to the 9th day, and the second period T22 is, for example, a 12-day period from the 10th day to the 21st day.
[0072] In the first period T21, the raising light is selectively irradiated to the rearing area 70 . The average light intensity of the growing light in the first period T21 is about 10 (p.d.u.).
[0073] In the second period T22 and the late growing period, blue light is irradiated in addition to the growing light. That is, the mixed light of growing light and blue light is irradiated.
[0074] The average light intensity of the growing light and the average...
