In winter, the weather is cold and the sunshine hours are short. Many ducks have problems such as suspension of production due to stress. Therefore, in the winter, necessary management measures should be taken to reduce stress and reduce economic losses. The specific practices are as follows:
1. Do a good job in the cold and warm work of the shelter. When the weather is cold, it must be ensured that the temperature in the shed is above 5°C at night. While keeping warm, you should pay attention to ventilation and anti-thief wind, but also pay attention to keep the shed clean and dry.
2. Provide nutritionally complete feed. In the cold season, the egg-duck consumes part of the heat to resist the cold invasion. Therefore, the feed of ducks and ducks should be rich in nutrients and should be properly matched. It is necessary to appropriately increase high-energy feed such as corn. Special attention should be paid to ensuring the ratio of calcium in feed. In addition, a variety of vitamins should be added to feed the ducks and night meals. To keep the laying ducks at a high rate of egg production, they must be fed 4 times a day, the fourth meal should be fed at night, and the duck group should be fed a night meal at night between 10 and 11 hours.
3. Provide enough clean and warm water. When the temperature outside the shed is less than 5°C, if the ducklings drink very cold water, it will cause stress and reduce the egg production. In addition, prevent water pipes from freezing and prevent water cuts.
4. Ensure the light intensity. In the evening and in the morning, it is advisable to use a 40 watt bulb for every 20 square meters in the duck shed.
5. Increase exercise. The conditional farms can drive the ducks to the sports field outside the home in the warmer weather at noon. When the ducks are released, the keeper must clean the shed and disinfect it, and open the doors and windows for ventilation.
6. Time-cut ducks and sick ducks were singled out in a timely manner. After the ducks enter the shed in the evening, they must be diligent in inspections and observations. It is found that ducks that have stopped production and weak ducks should be singled out and eliminated from the ducks in a timely manner to reduce feed loss.
7. Do not feed mildew feed. In cold, rainy and snowy weather, poor feed containment can easily cause freezing and mildew, resulting in aflatoxins. Ducks are very sensitive to this, so they must not feed moldy feeds. When grass mats become moldy, they must be promptly removed and replaced.
8. Pay attention to disease prevention and treatment. An attenuated attenuated vaccine for duck quail chickens was given intramuscularly 1 month before and 1 month after the laying of eggs. 1.9-2.0 ml of ducks per duck was prevented. 10 days later, live vaccines against live pasteurition of birds were given. Each was 1.5-2.0.
