What is the suitable temperature for free-range chickens in winter?

The most suitable living temperature for laying hens is 18℃, and the temperature of henhouse should be kept above 10℃ in winter. Generally, wind shields are set around the henhouse, and plastic sheets are covered on the doors and windows to block the air leakage of the walls and prevent the henhouse from entering the "thief wind" and ventilation. \x0d\ What about free-range chickens in winter \x0d\ 1. In winter, the henhouse should be moved to the leeward and sunny place. \x0d\ 2。 Scatter chicken food in the sun and let it eat freely. At the same time, let them bask in the sun more, which not only keeps warm but also promotes digestion. \x0d\ Third, the light is obviously insufficient in winter, so it needs to be supplemented manually to make the overall light reach about 16 hours. \x0d\ IV. Deficiency of vitamin supplementation by feeding more stems and leaves; Supplementing corn, sorghum and other energy feeds; Adding a small amount of Chili powder to the feed not only warms the stomach but also promotes digestion. \x0d\ x0d \ How to keep free-range chickens in winter \ x0d \ If hens don't stop production in winter, effective feeding and management measures should be taken according to the requirements of temperature, light and nutrition for laying hens. \x0d\ 1。 Cold and heat preservation. The most suitable living temperature for laying hens is 18℃, and the temperature of henhouse should be kept above 10℃ in winter. Generally, wind shields are set around the henhouse, and plastic sheets are covered on the doors and windows to block the air leakage of the walls and prevent the henhouse from entering the "thief wind" and ventilation. Second, increase the light. Light can not only enhance the physique of hens, but also promote the secretion of pituitary hormones in hens, so that hens can lay eggs vigorously. Therefore, due to the shorter weather in winter, artificial light should be supplemented to stimulate laying hens to lay more eggs. Usually, electric lights are installed in the henhouse, so that hens can get 15 hours of light. You can also turn on the lights in the morning and turn off the lights at night, so that the illumination time of laying hens in winter is 0.5 ~ 1 hour longer than that in summer and autumn. \x0d\ Third, increase nutrition. The cold weather in winter increases the energy consumption of laying hens, which needs feeding and supplementation. Therefore, the energy level of laying hens' feed should be appropriately increased in winter, reaching 12 megajoules per kilogram of feed. Therefore, 1% corn can be fed. In addition, increasing the amount of vitamins in the feed at the same time can improve the egg production of laying hens. According to the experiment, adding double amount of vitamin A and D3 to feed in winter can improve the egg laying rate by more than 3.5%. In addition, feeding times can be increased to encourage laying hens to eat more. \x0d\ IV。 Strengthen the prevention and control of infectious diseases. Winter is the mobile season of respiratory infectious diseases in chickens. Once the disease is found, the corresponding drugs should be used for early prevention. At the same time, chickens can also be disinfected once every 5 to 7 days with disinfectants such as Baidusha. Dipyridamole can kill Escherichia coli, Salmonella, Marek's disease virus, Newcastle disease virus, etc. When spraying 1∶200 or 1∶300 times water solution. ).
