Mallard duck breeding technology

At present, wild ducks reared in China are mainly mallard ducks. Mallards, also known as big ducks and official ducks, are ancestral birds, geese, ducks, and ducks. They are the ancestors of domestic ducks and are distributed throughout the world. Its production performance has been improved to varying degrees compared to the wild state.
Mallard is a meat-type waterfowl, its slaughter rate is significantly higher than Beijing duck. - Only female ducks can produce 90 - 110 eggs in an egg-laying period, and the average egg weight is about 63 grams, while the annual production of domestic ducks in northern China is only about 60 eggs. Mallards are more tolerant to crude feeding, and the combination of grazing and supplementation can save 15 % - 20 % of the cost of feed more completely. Wild ducks have strong gregariousness and are suitable for intensive rearing. Their use as hunting and hunting rare birds in ecotourism is a new business idea for modern breeding wild ducks. In addition, the duck's fine feather and warmth is a good raw material for the development of down products.
The large-scale breeding of mallards has only just begun in China, and its key farming techniques are described below.
(1) Ensure proper hatching conditions The hatching period of wild duck eggs is slightly shorter than that of domestic ducks, 0.5 to 1 day, and the incubation temperature can be the same as that of domestic ducks in the early stage. However, in the later period, especially during the hatching period, attention should be paid to increasing the incubators. Relative humidity, and pay attention to ventilation. In addition, the ducklings of the mallard ducks have poor self-propelled shelling ability, and they are required to implement midwifery on young chicks that are difficult to break shells.
(2) To prevent over-humility in the brooding environment. Wild ducklings like to gather around the water fountain to play with water, so care should be taken to separate the drinking fountain from the bedding or heat source - to prevent excessive humidity in the brooding environment. The best conditions are The brooding room is equipped with a floor drain. Excessively moist environment will often make grass bedding mildew, produce mold, so that ducklings appear tears, blindness or diarrhea and other symptoms, in serious cases will also cause death.
(3) The brooding temperature should not be too high. The wild ducklings should have a good adaptability. At 1 to 3 days of age, the brooding temperature should be kept at 29 degrees Celsius, then lowered by 1 degree Celsius every two days, and after two weeks when the outside temperature is higher than 20 degrees Celsius. Take off, but warm it up at night. Wild ducklings are usually fully deinsulated around the age of 3 weeks. Preheating is too early, absorption of yolk is incomplete, duckling development is often delayed, growth is blocked, and resistance is low.
