(1) The rearing house requires that the duck house can be adapted to local conditions, and that the empty house or simple grass and bamboo structure can be used, but it must be sturdy and durable. The farmed product duck only needs to dig a pool, and the breeder duck needs a sports field and a water field. Build Skynet, which is about 2 meters above sea level or on the ground. Surrounding the net, deep and underwater, and Skynet into a closed body to prevent wild ducks fly away. Skynet and fence holes are 3 cm and 3 cm. Nylon nets or rope nets are available. Each 100 ducks are reared in an area of ​​5 to 7 square meters for 1 to 30 days. The playground and water field are 10 square meters each. The 37-70-day housing area is 10-15 square meters, the sports ground is 20 square meters, the water field is 15 square meters, the area of ​​the housing more than 71 days is 15-20 square meters, the sports ground is 20 square meters, and the water field is 15 square meters.
(II) The requirements for feeding the mallard are basically the same as that of the domestic duck. Under normal circumstances, it is also possible to feed the full-price pelleted feed for ducks. For example, self-prepared mixed feed is formulated as follows (for reference): 1-30 For days, corn 47.3%, wheat 15%, wheat bran 10%, soybean cake 22%, fishmeal (import) 4%, shell powder 1.5%, salt 0.2%; 31-71 days, corn 40.8%, wheat 14.5% 17.5% of rice bran, 8% of rice, 13.7% of soybean cake, 4% of fishmeal (imported), 1% of bone meal, and 0.2% of salt. The above formulas should be mixed with poultry multidimensional and trace element additives.
(III) Feeding Management
1. Ducklings (1-30 days old): (1) Temperature control: 1-3 days 27-29°C, 4-6 days 25-26°C, 7-10 days 24-25°C, 11-20 days 17 -19°C. Flat brooding, the floor should be covered with soft straw, and separate small columns, about 2 square meters per column, each column installation of insulation lamp 1; 7 days in each column 50-70 ducklings. Because ducklings have the nature of a sleeping pile, they should be on duty day and night. They should be hand-picked once every 1 hour to prevent the heap from dying. Adjust density after one week. (2) Open food: feed water after drinking first, and add appropriate amount of compound-dimensional B agent to drinking water. Do not cut off water. Feeding times are generally 7 times a day for 10 days and 4-5 times a day for 10 days.
2. Breed ducks (31-70 days): Feeding density is 10-15 eggs per square meter, and care must be taken to prevent flight. You can also arrange to put water after feeding, put a few large basins in the house, and have the conditions to work in the sports field. Generally 9 weeks old, each body weight reached 1 167.1 grams, and consumed 3 120 grams.

Ducks or ducks can be selected for feed. Full price feed, while paying attention to the ratio of calcium to phosphorus. At the peak of egg production, attention should be paid to protein content and feeding times in order to achieve high and stable yields.
