From the beginning of autumn to early winter, young ducklings are bred. After 60-70 days of feeding, the weight of each duck can reach 2-3 kg and the ratio of meat to meat is 1:2.5-3. (a) Select young ducklings require ducklings to hatch properly, light hair and cover the navel, abdomen soft and flexible, anal clean, thick legs, large mouth, eyes are God, lively and strong. (2) Ducklings Feeding ducklings should be promptly fed with 0.01% potassium permanganate solution after being hatched, and should be consumed once every 1.5-2 hours. At the same time, cook half-cooked, not soft or hard rice, add appropriate amount of sugar, and spread it on a plastic tray with a plastic sheet. Let the duck eat early, feed 80% of the time, and feed it once every 2 hours. . At the age of 2-4 days, drinking water will be fed 5-6 times a day, 4-5 times at 5-15 days, and 3-4 times after 15 days of age. After the first drink or feed, the feed is gradually fed from the 4th day of age, and the feed is fed to the 10th day of age. Reference formula (%) corn 46, broken rice 10, wheat bran 6, rice bran 6, fried beans 10, fried pea 10, fish meal 6, cocoon 4, bone meal 1, gypsum 1. For young ducklings to be fed with appropriate amount of green feed, 4–10 days old green feed can account for about 2% of the diet, after 10 days of age can account for 30% -40%. Ducklings should be kept at 27-30 degrees at room temperature for 7 days. After cooling for 7 days, they should be cooled 1 degree each day. After 15 days of age, they should be kept at 15 degrees. After 20 days of age, they should be kept at room temperature. After ducklings are hatched for 2-3 days, ducklings can be loaded into the water for 5-7 minutes. Before the 7th day of age, the water is released 2-3 times a day for 10-20 minutes each time. Each feed is finished after 7 days of age. The ducks were placed in shallow water barriers 8-10 cm deep. After 15 days of age, the depth of the fenced water was increased to 15-20 cm. (c) Ducks are bred in ducks weighing 25-55 days. Feeding is mainly based on "feeding, grazing as a supplement, feeding in groups, and reducing fines". The feeding grounds can be set beside the pond or river bay. Enclosed air circulation. A 60-centimeter tall duck bar with a height of 5 square meters is used to house ducks, 20-30 ducks, 70-100 per group, separated by fences. In the column on the side of the sidewalk, the troughs and troughs are placed outside the bar. It is required that each duck should occupy 5–10 cm of troughs. Feed formulation (%): corn 62, wheat bran 15, fried pea 6, fish meal 7, vegetable cake 7, bone meal 2.8, table salt 0.2. Feed 4 times a day, feed water while feeding, and try to eat as much as possible. At the same time to add green material, the ratio of green material and compound feed is 1-1.5:1. During the feeding process, it is necessary to strengthen the grazing of ducks in the bath. Graze once a day before 11 am and after 16 pm. Do not grazing for more than 1 hour each time. After grazing, wait for the feathers to dry before entering the fence. (D) Intensive finishing ducks raised to 50-55 days is the best period of intensity fattening. High-energy, low-protein compound feeds are used during fattening. Reference recipe (%): pre-fattening period is corn 35, flour 26.5, rice bran 30, fried beans 5, shell powder 2, bone meal 1, salt 0.5; late corn 35, flour 30, rice bran 25, sorghum 6.5, shell powder 2 Bone meal 1, salt 0.5. Fertility methods are: 1 free to feed fattening. The compound feed is added with water and wet for 3-4 hours until it is fermented and fed, 4 times a day, 1 night feeding, and feeding water while feeding. After feeding, the duck was put into the bath. The duck house should be dark. The duck farm should be clean and well ventilated. 2-column fattening. Divided into small columns with bamboo poles, each column can accommodate 2-3 ducks. The height of the bar is 45-55 cm, which is suitable for ducks to stand. Drinking fountains and feeding troughs outside the bar allow ducks to stick their heads to eat water. Feed supply should be adequate, feed 3 times during the day and 1 time at night. 3 feeding and fattening. Mix the feed with warm water and make a strip of 1-5 cm in length. Fill the duck mouth artificially after it is cool. Begin feeding 3 times a day, 3-4 times each time, then gradually increase to 5-6 times, each time 5-8. After filling, drink enough water for a 30-minute water bath every day to facilitate digestion and fattening. The fattening period is generally 10-15 days. When the duck has a body weight of 2-3 kilograms, it senses fat thickening by hand touching the skin, and the feather plume of the wing feather is transparent. (e) Before the prevention of disease prevention and ducking, the ducklings and duck farms shall be completely disinfected with bacterial poisoning or by using Suer pens. Sweep ducks and keep them well ventilated. 20 ml of ducklings were given 1 ml of attenuated vaccine to ducks and 20 ml of ducklings were given 2 ml of cholera vaccine every 30-40 days.
