Embodiment 1
[0028] In order to obtain the best spectrum of LED lights combined with natural light, figure 2 As shown, chicken coop 1 is 19m long, window 2 is 1.5m long, and there are 5 in total. Place two 1m×1m chicken coops at a distance of 1m from each window. The two chicken coops next to the same window 2 form a group, and the two chicken coops in the same group are close together and facing the window. The bottom of the chicken coop is 0.5m from the ground, and an LED light 4 is installed directly above the bottom of each chicken coop 1.5m away. There are five types of LED lights 4, and the LED lights 4 in the two chicken coops of the same group are The same type is controlled by one line, and five control lines are connected with switch 6 by electric wire 5, and 3 is the chicken coop door.
[0029] The experiment set up five experimental groups ①, ②, ③, ④, ⑤, using LED lights A, B, C, D, E respectively, corresponding to figure 1 In 7, 8, 9, 10, 11, the parameters of various types...
Embodiment 2
[0036] The chicken coop 1 is 20.8m long and 12m wide, the windows 2 are 2.6m long, 8 in total, the LED light group 4 lamp tubes are 0.6m long, installed at a distance of 1m from the wall and 2m between adjacent ones, a total of 40 groups, each in two rows The LED lamp 4 is a control circuit connected to the controller 6 through the electric wire 5. The LED lamp 4 is an LED lamp A with a color temperature of 6172K, a dominant wavelength of 492.5nm and a peak wavelength of 450.5nm, or a color temperature of 1831K and a dominant wavelength of 588.3nm. LED light B with a peak wavelength of 591.1nm, or install LED light A and LED light B at the same time, LED light A and LED light B are turned on or off according to different growth stages of chickens, and use LED light A or LED light B throughout the whole breeding process Or use LED light A in the early stage and replace LED light B after 40 days of age, that is, in 1-40d, LED light A in the LED light group is on, LED light B is o...

Abstract
The invention discloses a method and a device for light supplementary by combining the natural light in daytime and artificial supplementary light at night in a barton. The method comprises the following steps: breeding chickens in the barton allowing natural light to enter, and mounting an LED lamp A or an LED lamp B or mounting both the LED lamps A and B for light supplementary in the barton; wherein the color temperature of the LED lamp A is 6,172 K, the dominant wavelength of the LED lamp A is 492.5 nm, and the peak wavelength of the LED lamp A is 450.5 nm, the color temperature of the LED lamp B is 1,831 K, the dominant wavelength of the LED lamp B is 588.3 nm, and the peak wavelength of the LED lamp B is 591.1 nm; the lamps for light supplementary can also be the LED lamps which have similar spectrum with the LED lamp A or the LED lamp B; in daytime, the chickens receive the natural light penetrating through a window in the barton or are sent out of the barton to receive illumination; and at night, the chickens receive artificial supplementary light to enable the average light intensity of the contact surface of chicken claws to be 5-30 Lux. During the whole breeding process, the LED lamp A or the LED lamp B is used, or the LED lamp A is firstly used before the chickens are of 40-day-age and then the LED lamp B is used. The switch of each LED lamp is controlled by a hand switch, an autotimer or a controller. The method and the device disclosed by the invention are applicable to breeding of yellow feather broilers in large-scale bartons.
Description
technical field [0001] The invention relates to poultry houses, in particular to a method and device for supplementing light in a poultry house that combines natural light during the day and artificial light supplementation at night. Background technique [0002] Chicken is a light-sensitive animal, and changes in light conditions will have a certain degree of impact on the physiology, behavior, and growth rate of chickens. The general situation is that people blindly supplement light in order to obtain higher economic benefits. Improper selection of supplement light sources will not only fail to increase the growth rate of chickens, but will also affect the growth welfare and health of chickens and reduce the quality of chickens. [0003] The traditional light supplement technology generally uses incandescent lamps and fluorescent lamps for supplementary light. These two light sources have high energy consumption, short service life and poor controllability. Compared with ...
