In winter, the temperature is low, the sunshine time is short, the egg laying rate of ducks is low, and even production stops. However, from the perspective of production practices, as long as the management of feeding is strengthened, the egg production rate of female ducks that are hatched in the spring can still be maintained at more than 80%. 1 cold insulation. The optimum temperature for laying ducks is 13 °C to 20 °C, and the minimum should not be less than 6 °C. Therefore, the duck house must block wall joints, close the doors and windows, especially the north window should be blocked. At night and when the temperature is low, hang grass curtains on the doors and windows, spread some straw or straw on the ground, and spread thicker around them. Every night ducks add new grass before entering the house, while raising the stocking density, raising 8-9 pigs per square meter. The duck house should also pay attention to ventilation, every time the duck is released, it should open the door and window, into Close it again. 2 Adjust the diet. Winter ducks have higher energy requirements, so we must appropriately increase the proportion of corn and other energy feeds, protein content is reduced to 15% to 17%, and pay attention to increase cabbage, radish and other green feed to ensure that ducks need vitamins. 3 Carefully feed. Adhere to warm food and drink warm water to reduce the loss of duck body heat. Feed 3 times a day, feed it once more at night, and provide plenty of water. Usually first feed, drink, feed green feed. Changing feeds should be gradual and not too sudden. 4 Scientific management. Put ducks late every morning and duck early in the evening. Reduce the number of water discharges, shorten the time for launching water, and release water once in the morning when there is sufficient sunshine. Put water in at least 3 days. Before each duckling is released, first open the window noise duck, pick up the duck, let it slowly move around in the house, and then release the water when about 80% of the ducks have a strong call. When the climate is too cold, ducks must be disturbed to enhance activities, promote appetite, and improve the ability to keep out the cold. When natural light is less than 15 hours, artificial light supplements should be performed in time. In addition, try to keep the duck house quiet and avoid frightening herds. 5 Prevent disease. The winter duck body's defensive ability is reduced. In the case of poor feeding and management, it is susceptible to disease, which affects the production of eggs. Therefore, the duck house and the event site are disinfected once a week. Find out the cause of the epidemic and promptly treat it.
