Method and device for light supplementary by combining natural light in daytime and artificial supplementary light at night in barton

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 ...

AI Technical Summary

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 improper selection of artificial supplementary light sources in the chicken coop, the purpose of the present invention is to provide a supplementary light that combines natural light in the daytime and artificial supplementary light at night in the chicken coop The method and device avoid adverse stress to the chickens caused by the large difference in light spectrum between day and night, and control the average light intensity of the contact surface of the chicken feet at a suitable level by installing an appropriate number of LED lights with a suitable light spectrum in the chicken house , promote feed digestion and nutrient absorption by chickens, reduce feed-to-meat ratio, increase body weight and uniformity of chickens, enhance physical health and disease resistance
