Problems solved by technology

[0005] In order to solve technical problems such as low health status, high mortality rate and low production efficiency caused by too long artificial lighting time in large-scale chicken houses, the purpose of the present invention is to provide a combination of natural light and LED lighting in chicken houses. The supplementary light method and device, by installing an appropriate number of LED lights in the chicken house, control the lighting time of the LED lights in an appropriate range, control the average light intensity of the contact surface of the chicken feet at an appropriate level, and promote chickens to the feed. Digestion and nutrient absorption, reduce feed-to-meat ratio, increase body weight and uniformity of chickens, enhance physical health and disease resistance

Embodiment 1

[0026] In order to obtain the best supplementary light duration of LED lights at night, such as figure 1 As shown, chicken coop 1 is 15.5m long, window 2 is 1.5m long, and there are 4 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 away from the ground, and a yellow LED light 4 is respectively installed directly above the bottom 1.5m of each chicken coop, and the LED light 4 is a yellow LED light with a length of 0.6m. Two LED lamps 4 of one group are controlled by a line, and four control lines are connected with switch 6 by electric wire 5, and 3 is the chicken coop door.

[0027] The experiment set up four experimental groups Y0, Y4, Y8 and Y12 (Y represents yellow, and the number represents the length of light supplement at night), corresponding to figure 1 ...

Embodiment 2

[0033] like figure 2 As shown, chicken coop 1 is 20.8m long and 12m wide, window 2 is 2.6m long, 8 in total, LED lamp 4 is 0.6m long, installed at a distance of 1m from the wall and 2m between adjacent ones, 48 ​​lights in total, each The two rows of LED lamps 4 are a control circuit, which is connected with the controller 6 through the electric wire 5 . The said LED lamp 4 is a yellow LED lamp with a length of 0.6m. The average light intensity from the ground is 15 Lux. Light, the switch of LED light 4 is controlled by switch 6, and 3 is the chicken coop door.

[0034] During the brooding period of 1-14 days, 3,000 yellow-feathered chickens received natural light during the day, and received 30 Lux yellow LED fill light from 18:00 at night to 6:00 the next day. After 14 days, weak and unhealthy chickens were eliminated, and the remaining 2,500 chickens were placed in chicken cages. House 1, add water and feed every day until the end of 80d.

Abstract

The invention discloses a henhouse natural light and light emitting diode (LED) combined light supplementary method and a device. Chickens are bred in a henhouse where natural light can access, and the chickens in the henhouse receive light supplement through the natural light penetrating through windows or the chickens are released to the outside to receive lighting in the daytime. Yellow LED lamps are installed in the henhouse, the distance between adjacent LED lamps is 1-3 meters, average light intensity of chicken feet contact area is 5-30 Lux, in the evening, specifically, after seventeen to eighteen, lamps start to light for 6-10 h, and switches of the yellow LED lamps are controlled by a manual switch or an autotimer or a controller, feed digestion and nutrition absorption of the chickens are promoted, feed conversion ratio is lowered, body weight gain and chicken evenness are increased, and physical health and epidemic-disease-resistance ability are strengthened. The henhouse natural light and LED combined light supplementary method and the device are mainly used in feeding of yellow feather broilers in large scale of henhouses.

Description

technical field [0001] The invention relates to poultry houses, in particular to a light supplement method and device combining natural light and LEDs in a chicken house. 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 use long-term supplementary light in order to obtain higher economic benefits. Blind supplementary light 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 conventional light sources, LED light sources have high photoelect...
