Management measures of non-stop production of laying hens in winter

In order to keep the hens from stopping production in winter, effective feeding and management measures should be taken according to the requirements of temperature, light and nutrition of laying hens. First, prevent cold and keep warm. The most suitable living temperature for laying hens is 18 ℃, and the temperature in the henhouse should be kept above 10 ℃ in winter. Generally, wind barriers are set around the chicken coop, and plastic sheeting is added to the doors and windows to plug the leaking cracks in the walls to prevent the chicken coop from entering the "thief wind". Second, increase the light. Light can not only enhance the physique of hens, but also promote the secretion of pituitary gland hormones and exuberant egg laying vitality. Therefore, due to the shortening of winter time, artificial light should be supplemented to stimulate laying hens to lay more eggs. Electric lights are usually installed in the henhouse so that the light received by the hens can reach 15 hours. It is also possible to turn on the lights early in the morning and turn off the lights late at night, so that the lighting time of laying hens in winter is 0.5 hours longer than that in summer and autumn. Third, increase the times of feeding. Because of the low temperature in winter, laying hens must take enough nutrients from their feed to resist the cold in order to ensure their high yield. The number of feeding can be increased to encourage laying hens to eat more. Fourth, increase nutrition. When it is cold in winter, laying hens consume more energy and need to feed and replenish themselves. Therefore, the energy level in the feed of laying hens should be properly increased to 0.12 megajoules per kg in winter. In addition, increasing the amount of vitamins in feed in winter can increase the egg production of laying hens. According to the experiment, adding double amounts of vitamin An and D3 to the feed in winter can increase the laying rate by more than 3.5%. Fifth, strengthen the prevention and control of epidemic diseases. Winter is the mobile season for respiratory infectious diseases in chickens. Once the disease is found, corresponding drugs should be used for early prevention. At the same time, chickens can be disinfected with disinfectants such as Baiduxie every 5-7 days.
