Reasons for controlling Light during the breeding period of Meat Breeders

The purpose is to make the broiler breeders use a short or gradually shortened light period in the growth stage, or in conjunction with restricted feeding, to control the timely opening of new hens, and to gradually prolong the light time close to the beginning of laying, and gradually enhance the stimulation to make it reach the egg laying peak in time, without causing cloacal eversion of some hens due to the sudden increase of light time.
