1. Ensure that the most suitable temperature for duck production in the duck farm environment is 15-22°C, and the lowest should not be lower than 5°C. Therefore, it is extremely important for the winter duck house insulation and cold protection. Before winter, ducks can be sheltered on the west and north sides to build a protective wall to increase the temperature. In front of the duck house, a transparent plastic cloth canopy can be used to increase the temperature. At night and when the temperature is low, the duck canopy and the shed can be covered. Straw insulation. At the same time, dry duck husks, rice bran or sawdust, crushed wheat stalks, etc. are placed in the venues of the duck houses, and they are replaced 2 or 3 times a week. Appropriately increase the overnight density of ducks, 8 to 10 per square meter. The duck house must not only reach the proper temperature, but also keep it clean. The duck house should have a brick and cement structure and be provided with ventilated doors and windows to allow frequent ventilation in warm weather. 2. Increase the necessary thermal energy feed Winter ducks have higher energy requirements. Therefore, it is necessary to appropriately increase the proportion of energy feeds such as corn, rice, bran, and bean cake, and pay attention to increase green feed such as fresh cabbage and carrots. Change the feed to be carried out step by step, feeding 3 to 4 times a day, depending on the situation at night can be fed again, and provide enough clean drinking water. For warm, warm water feeding ducks. 3. Dry Sheer Yinyu As the saying goes, “dry duck ring†means that there should be sufficient drinking water during the day, and there should be a dry and warm rest and egg production site after entering the shed. The grass should be grounded and the sun should be used during the day so that the chest and the abdomen are not cold when the duck is lying down, and the feathers under the belly are not wetted by the manure. Outside the shed, circle a “little canteen†to communicate with the shed. Feed the water in the canteen, eat, drink, and then enter the circle. 4. Vitamin supplements often require additional cod liver oil or vitamin A, D3, E, etc. in the duck diet. Ducks generally lay eggs in the early morning. Therefore, ducks must maintain a high blood calcium concentration in the early morning, otherwise they will produce sand shell eggs, misshapen eggs, and even cause decreased egg production. In the preparation of egg-laying duck feed to ensure the supply of calcium, commonly used stone powder and shell powder. 5.Scientific Lighting Management Ducks need 14 to 16 hours of light each day during their egg production. Winters are short and long nights, and the light illumination of ducks is insufficient. Therefore, 1 ç›60 watt incandescent bulbs should be installed in every 20 square meters in the duck house. The height of the bulb should be 2 meters from the height of the duck body, and the combination and coordination of natural light and artificial light should be mastered. Generally, it is 17 to 20 times a night. Hours and fill the light from 4 to 8 am the next morning. 6. Sports ducks are used to stock animals and artificially increase the amount of activity during captivity. Ducks in the late stage of production need more activities. If possible, keep the sports venues as large as possible. In suitable sunny weather, let the ducks do some activities in the circle first. When the body temperature of the duck rises, the ducks can be opened and the ducks can be launched. According to the degree of temperature decrease, the number of discharges can be reduced and the time for launching can be shortened. 7. There must be a certain number of male ducks in the appropriate duck population. A small herd was reared with 1 male duck for every 100 female ducks; a large herd was raised and 20 male ducks were raised for every 2000 female ducks. The proportion of ducklings for eggs is 20:1 to 30:1. The male ducks are isolated during the period of production and during the moulting period. 8. To prevent disease duck house and activity site should be disinfected once a week, found that the disease should be promptly identified and timely symptomatic treatment.
