1. Streamlined ducks. After entering the winter, according to daily observations, the old, weak, sick, stump ducks, low-yielding ducks, and discontinued ducks of ducks were singled out in time and eliminated. The egg ducks with good production performance and robust physique are left as the core group of winter egg production, laying a good foundation for improving the egg production rate of ducks. 2. Cold insulation. The suitable temperature for laying ducks is 10°C-20°C. The cold winter weather is not conducive to laying duck eggs, we must pay attention to do a good job of cold insulation work, can be appropriately increased breeding density, 8-9 per square meter can be raised to facilitate mutual heating between ducks and ducks. 3. Timely deworming. After winter, the parasites should be driven to the ducks in time. The parasites can be fed into the fodder after crushed and dredged. This can effectively reduce the damage of parasites to ducks, enhance the constitution of ducks and ducks, and improve the production of eggs. Rate and increase egg weight. 4. Reasonable ingredients. In addition to laying eggs in winter, ducks also have to withstand the cold. Therefore, it is necessary to increase the heat energy in the feed of the duck and raise the level of metabolic energy in the feed. The reference formula is: corn 40%, bran 22.5%, broken rice 10%, rapeseed cake 5%, bean cake 10%, fish meal 7%, bone meal 3%, oil 2% and 0.3% salt, in addition, lack of green feed In the case of this, add 0.2%-0.5% of multidimensional pigment. 5. Feeding and drinking water. Feeding and drinking water is an important part of improving duck breeding. When feeding, the prepared feed should be mixed with warm water and mix well to loosen into hands to form a mass. The material temperature should be about 38°C, and be mixed with heat and feed. Usually fed four times a day, fed every morning at 5 o'clock in the morning, 10 o'clock in the morning, 3 o'clock in the afternoon and 7 o'clock in the evening. Around 12:00 in the evening, you may consider feeding again. Generally, feeding ducks with no feed at night can increase the egg production rate. When feeding at night, attention should be paid to two points: one is to supply enough clean and warm drinking water, cold water can easily cause stress and reduce egg production; the other is that the protein fed at night should not be too high, try to make the ducks full Just fine. 6. Add light. Eggs and ducks require 16 hours of light each day during the egg production period. Short winters and long nights, natural light is insufficient and must be artificially supplemented with light. 7. Environmental health. Indoor and outdoor playgrounds in duck houses must be cleaned regularly, food troughs and sinks must be washed and disinfected, and feed must be kept on moldy feeds. The duck house should be provided with ventilation and ventilation to keep the air fresh. The grass should be kept clean and dry. 8. Disinfect regularly. Every week, 20% of lime milk or 2% of sodium hydroxide or 3% of compound phenol can be used to disinfect the housing area. Feeding tanks and utensils can be disinfected with 100 toxins. Green feed and drinking water can be treated with 0.02% potassium permanganate solution. 9. prevent disease. Doing a good job of prevention work is the key to ensure high productivity of winter ducks and ducks. To prevent duck gizzards, a duck dipped in attenuated vaccine was used. Ducks were injected with 1 ml of each pectoral muscle and ducks were injected once every 6 months. To prevent duck cholera, avian cholera hydroxide hydroxide vaccine can be used. Each chest muscle is injected with 2 ml and the immunization period is 75 days.
