FIELD: agriculture.
SUBSTANCE: invention refers to agriculture. Keeping of chickens in in-cage conditions is carried out on the background of intermittent light day with the three stage alternation of the periods of radiation of light sources and darkness using LED lighting. LED lighting of two color temperatures is used, with the first color temperature having the white warm spectrum with the color temperature of 2,800–3,200 K, and the second one has the white cold spectrum with the color temperature of 4,800–5,200 K. In the first and last periods of the light, the color temperature of the radiation of the light sources is provided within the range of 4,800–5,200 K, in the average period of light – within 2,800–3,200 K and when the light is first turned on, the smooth increase in illumination is carried out. In case of last switching-off of light smooth decrease in illumination lasting during 4 minutes is carried out.
EFFECT: increased productivity of chickens and the decrease in feeding for their maintenance are provided for.
