Duck high bed net raising is a new breeding technique that has been successfully explored in recent years. It has broken the traditional feeding methods of ducks that could not be separated from rivers and canals and ponds and marshes for thousands of years, and has opened up new ways for duck rearing. Compared with grazing and ground leveling, meat duck net culture has the advantages of labor saving, easy management, free from seasonal restrictions, fast growth of ducks, fewer patients, and high feed conversion ratio. 1. The bed house can be set up in the high-bed duck house, and the existing duck house and idle pig house and chicken house can be rebuilt or newly built. High-bed duck houses are required to have a good structure, with a height of 2.5 meters or more, and the ground should be set aside with a concrete graze. Drainage ditch is built in the house, and the sewage pool is outside. The net bed is about 1 meter high from the ground. Bamboo and wood are used to build bed frames and bars, and the top layer is padded with plastic mesh. A 0.5-meter-high fence is set on the outside of the grid, and a large area of ​​the net-bed can be used to separate multiple cells, and sinks and troughs are set in each cell. 2. Select suitable breeds Select fast-grown large meat duck breeds with fast growth, high feed conversion rate and gentle temperament, such as Cherry Valley Duck, Okubai Star Duck, Lijia Duck, Tianfu Duck and Beijing Duck. These breeder ducks can weigh up to 2 kg in 32 days under high bed conditions, and the ratio of feed to meat can reach 3.3 kg in 1.9 to 2:49 days, and the feed to meat ratio is 2.3 to 2.5. 3. Feeding management of meat ducks (1) Feed formula: Duckling formula (within 3 weeks of age): Crude protein 20%, calcium 1%, available phosphorus 0.5%; fertilizer formula (4 weeks old till slaughter): coarse Protein 16.7%, calcium 1.2%, available phosphorus 0.45%. At the same time add the appropriate amount of vitamins and trace elements, allowing them to eat freely. (2) Temperature: 1 to 3 days of age control at 32 to 33°C, 4 to 7 days of 28 to 30°C, and 1°C daily decrease to room temperature after 8 days of age. (3) Humidity: The humidity before 7 days of age is 70%, and it remains at 60% to 65% after 8 days of age. (4) Light: 24 hours light from 1 to 7 days old, 8 hours old to slaughter 23 hours light, 1 hour dark. (5) Drinking water: Continuous water supply throughout the day, allowing it to freely drink water. (6) Density: 25 to 30 eggs per square meter during the brooding period, and 7 to 10 eggs per square meter during the growth and finishing period. 4. Epidemic prevention and control Keep the duck house dry and hygienic, well ventilated, and often remove the feces under the bed. Houses are poisoned once a week with 100 toxins, peracetic acid and other ducks, and the outside environment is sprayed and disinfected with caustic soda every half a month. 7 to 10 days old ducklings were injected with duck polysomnitis-E. coli multivalent propolis double seedlings. In areas threatened with viral hepatitis in ducklings, hepatitis virus high-immune or hyperimmune egg yolk should also be injected around the age of 15 days. prevention.
