Measures to Improve the Survival Rate of Ducklings in Autumn

1. Make preparations before brooding.

(1) Maintenance and disinfection of the brooding house: The brooding house should be thoroughly cleaned and disinfected before entering the brood, and the ground and walls should be sprayed with 30% caustic soda or sprinkled with 10% to 20% of the quicklime emulsion. All utensils were rinsed thoroughly with 100% poison, and potassium permanganate and formalin mixed were used for closed fumigation for 36 hours. Then the windows were opened to remove gas.

(2) Prepare feeds and medicines: Prepare feeds with adequate nutrition, good palatability, digestibility, and commonly used drugs such as potassium permanganate, formalin, penicillin, streptomycin, oxytetracycline, chloramphenicol ,Various vitamins.

(3) Preheating of the brooding house: The brooding house is warmed to 32°C to 33°C 1 to 2 days before the chickling.

2, timely drinking, timely food. After 24 hours of hatching, ducklings should drink water and then eat. The ducklings must be quiet before entering the house to drink water. The water temperature is 30°C. The water is added to 2000 units of gentamycin per duck. Half an hour later to drink 50% of glucose and 0.1% of vitamin C water, easy to clean up the young duck gastrointestinal, eliminate meconium. After 5 hours, drink cold water. Drinking water should always be kept clean and fully supplied. After the ducklings drink water, they will have the performance to eat. At this time, they can eat. Feeding feed should be regular, qualitative, fixed, diligent, and observing to form a fixed management program.

3, brooding temperature and humidity. The ducklings have poor thermoregulatory capacity. When the ambient temperature is lower than 26°C, they are likely to induce respiratory diseases or death due to extrusion. If the temperature is too high, the ducklings are susceptible to dehydration. The optimum temperature for brooding is: 31 to 29°C in the first week, and 1 to 2°C in the week afterwards. The relative humidity in the house during brooding is 60% to 70%.

4, density and ventilation. The suitable density for the autumn brooding ducks is 1 to 2 weeks of age 35 to 30 per square meter, 3 to 4 weeks of age 25 per square meter, 5 to 6 weeks of age 15 per square meter, more than 12 weeks of age 6/ Square meters. When the ducklings rest, they often pound and sleep. If the temperature is too low, the heaping will be more serious and it will cause death, injury or "sweat" and coldness. Once the crowding phenomenon is found, immediately remove and disperse and adjust the temperature and replace the damp mat. When there are more ducklings, they should be reared in groups. It is advisable to use 250 to 300 ducks per group to separate the ducks of different size and strength. Open doors and windows for ventilation before and after noon every day to improve the home environment.

5. Management of water release and grazing. The 1-week-old ducklings, which are raised on the ground, are allowed to exercise freely and feed on the floor and in the pool when the weather is fine, and once in the afternoon and afternoon. Grazing time should be extended gradually thereafter.

6, strengthen the epidemic prevention system. Strict implementation of the immunization program, in particular the timely injection of duck attenuated vaccines, duck viral hepatitis vaccines and live attenuated bacteriophage bacterins to ducklings, strict disinfection of air, environment and utensils, and addition of ducklings in feed within 1 week. 0.2% oxytetracycline base, gentamicin (2500 units each).
