In winter, the cold weather and short illumination are the lowest season for laying ducks. However, if the husbandry is managed properly, the egg production rate of the new female duck can be stabilized at 80% or more. The main points of its feeding tube are as follows. The rearranged herd is grouped on the duck herd and the old, weak, sick, disabled and low-yielding ducks are resolutely eliminated to reduce death and feed consumption. It is extremely important to control the temperature and temperature of wintering ducks at room temperature. Keeping the temperature in the night shed above 5°C can ensure high egg production rates. This requires that after the ducks are fed every night, the duck sheds must be enclosed and enclosed. Around the shed, straw or wheat straw can be used to wrap around the shed, and the surrounding area is covered with a layer of plastic film. In particular, the covering grass on the roof can not be less than 5 cm thick. In the laying area around the inner wall of the duck house, paddy grass is filled with a clean, soft straw or wheat straw with a thickness of 30 cm. After the eggs are shed in the morning, the old grass in the nest can be spread in the duck house. Before entering the house, add new grass for the production of egg nests to gradually accumulate mat grass. In winter, the nutrient duck must not only keep cold but also produce eggs. Its energy consumption is very large. It is necessary to appropriately increase the proportion of corn and other energy feeds. The amount of feed is 10%~15% higher than summer and autumn, and sufficient green feed or timing is provided. Vitamin A, vitamin D, vitamin E If you can add 3% to 5% fat to the duck and duck feed, the green feed such as chopped cabbage or radish cherry will be supplied once a day at noon. Adding night foods Winter nights are long, and the nighttime temperatures are low. If you can feed a warm feed at night, it will not only increase the nutrition of ducks and ducks, but also help the ducks to keep warm and increase the egg production rate by more than 10%. However, at night feeding should pay attention to two points: First, must provide warm drinking water, and second, night food in corn and other high-energy feed, protein can not be too much. Hot Drink Cold winter weather, ducks consume more heat energy. Therefore, it is necessary not only to provide sufficient feed, but also to pay attention to the fact that hot drinks are used for warm drinking. Fine ingredients must be prepared with hot and cold water. Drinking water must also be fed with hot and cold water, and the temperature should be kept at about 38°C. Avoid drinking ice water, this is crucial. Filling the light In winter, the natural light is less, and the activity of the secretory glands in the duck's pituitary gland is reduced, which results in a significant decrease in the egg production rate. This requires the artificial supplemental lighting. The general requirement is that the daily lighting time can not be less than 16 hours. The light can be filled in the duck awning in an amount of 1 to 60 watts per 30 square meters. The bulb is 2 meters high from the back of the duck and fitted with a lampshade. Turn on the lights at regular intervals. Trial practice proves that filling light can improve egg production by 20% compared to no light. More water and winter feeding ducks play 1 to 2 times a day, can increase the amount of activity and improve the resistance of ducks. Splashing is generally performed when the temperature is high at noon. If the temperature difference between indoor and outdoor is too large, open all the windows and adjust the temperature difference between the indoor and outdoor before going to the duck. Then, the ducks were circling around the house for 4 to 5 laps. When about 80% of the ducks screamed strongly, the ducks were allowed to swim in the pool. It should be noted that when the weather is harsh, the temperature is below -5°C and the ducklings do not have a strong tweet, do not swim. The density of high-density wintering ducks is preferably 8 to 9 per square meter to facilitate the self-incubation of ducks. Epidemic prevention Overwintering duck populations are affected by the need for heat preservation and ventilation. This requires special attention to the cleanliness of the house, and the frequent removal of trash from the house, such as excrement, grass and grass. After the ducks are released during the day, all doors and windows must be opened for ventilation to keep the house dry and tidy. Once the diseased duck is found, it is necessary to isolate the diagnosis and treatment in time, and emergency disinfection of the duck house should be performed.
