How to improve the survival rate of spotted-billed wild duck?

Spotted-billed wild duck has the characteristics of moderate body size, excellent meat quality, high reproductive ability and so on. In the wild, spotted-billed wild ducks hatch and brood naturally. In order to make full use of wild duck resources, protect the diversity of wild duck varieties, and meet the needs of the market, wild ducks have small food, are good at swimming and flying, and have strong resistance to adversity. Domestication and breeding of wild ducks must adapt to their biological characteristics and living habits. In particular, it is necessary to strengthen the feeding and management of the nestling period.

Maintain a suitable temperature

Ducklings have small body, short fluff and weak thermoregulation ability. The temperature requirement of the nursery was 28 ℃ at 3 days old, 25 ℃ at 7 days old, 22 ℃ at 14 days old and 22 ℃ at 15 days old. Never turn hot and cold.

Control the humidity of duck house

Wild ducks like water, but they are very afraid of dampness in the house. Therefore, the duck house is required to be clean and dry, with a relative humidity of about 65% within 10 days of age and about 60% after 10 days of age. Usually, you should bask in the sun frequently and change the cushion material frequently. Pay special attention to the humidity in the house during the rainy season.

Pay attention to the water release time

The first release time of wild duck is 24 hours and 26 hours after it comes out of its shell. Use a small sprayer (or sprinkler) to spray the duck body. 2-3 days old began to use basin bath method for water training, once a day in the morning and once in the afternoon, each time about 5min, the water temperature should not be lower than 15 ℃. Water from the reservoir began to be discharged at the age of 7 days, 3-4 times a day, each time 5~30min. Wild ducks have higher requirements for water quality, so the water of the pool should be changed frequently. The ducklings should change the water once a day within 7 days, once every 3-4 days after 7 days, and once in 2-3 days in high temperature season.

Feeding and management

Wild ducks have miscellaneous food habits and like to eat small fish, shrimp, shellfish, worms, cereals and aquatic plants, so the feed requires comprehensive nutrition and variety. Eating is usually carried out around 15min after the first release of water. The food can be fed with raw rice (which needs to be washed with clean water and then drained) and 10% glucose. It can also be fed directly to broiler chicks with broken pellets. With the increase of age, the pellet feed which is easy to digest, palatable, fishy and easy to peck is fed gradually. Require more than 20% crude protein, metabolic energy 11.~12.7MJ/kg, calcium and phosphorus content of 0.9% and 0.5% respectively. The digestive function of ducklings is not yet perfect, so they should be fed less many times and drink water before each feeding. The ducklings at the age of 10 days were fed 5 times a day, including 2 times at night, 4 times a day at the age of 11-20 days, twice at night, 4 times a day and once at night after 20 days of age. Ducklings like to pile up, even when the temperature is right. In order to avoid crushing injury, ducklings are required to be raised in small groups. Generally, 25 birds per m2 were reared in 1 week, 20 birds in 1 week and 15 birds in 2 weeks. Each group should be about 5 feathers. The duty should be strengthened within 2 weeks. If you find that you are piling up, you should separate in time.

Disease prevention and damage prevention work

During the rearing period of wild ducks, in addition to daily hygiene and disinfection, emphasis should be placed on the prevention and control of colibacillosis and avian influenza. Colibacillosis often occurs at the age of 20 to 30 days, and ciprofloxacin, gentamicin and other drugs can be used for prevention and treatment. The first immunization time of avian influenza is best determined after the detection of maternal antibodies. At the same time, rodent damage should be prevented in order to improve the survival rate.
