American duck feeding technology
The American wild duck is a breed of North American wild ducks. Its characteristics are: fresh meat, delicious, gentle, fast growing, easy to raise. First, the production performance in a simple shelter to raise, one-month survival rate of 98%, early maturity of breeding ducks, 164 days old production, annual production of about 100 eggs. The average weight of commercial ducks can reach 445 grams at 4 weeks and consume 1,081 grams. The average weight at 9 weeks is 1167 grams, which consumes 3,120 grams. Generally, they can be listed at 60-70 days of age, and the ratio of whole meat to meat is 3.7:1. Second, feeding and management 1. Site: Select ample water, good water quality ponds, reservoirs or rivers have a gentle slope of the place to build a field, the water surface does not need to be large, there is the best clean water. 2. Brooding: The temperature can be flexibly controlled according to the local conditions, so that the ducklings do not get together and do not breathe. Reference temperature: 1-3 days at 31-33°C, 4-6 months at 30-31°C, 7-10 days at 28-30°C, 11-20 days after 20-25°C. 3. Early feeding: Open ducklings or chicks, feed 7 times daily before 10 days of age, and then gradually reduce. All day for clean drinking water. 2-3 days old 23 hours of light, usually pay attention to the ground dry, clean. Reference feed nutrition indicators (day age, % crude protein, metabolic energy MJ/kg): 0-30 days old, 19%, 12.1 MJ; 31-70 days old, 16%, 12.1 MJ; 71-130 Day age, 13%, 11.7 MJ; duck 18%, 11.3 MJ. Calcium requirements: growth period of 0.6% -0.8%, calcium-phosphorus ratio of 1-1.5:1; egg production period of 2.7% -3%, calcium phosphate ratio of 3-4:1. 4. Drainage: Ducklings are very fond of water. Once they are 1 week old, they can release water. Usually after food, they can gradually increase the number and time of water discharge according to the temperature and age, until they are free to play. When you receive the ducks, you must wait for them to dry your feathers and return home. 5. Anti-flying: When the ducklings are 50 days old, the wing feathers are getting richer. At this time, we must pay attention to checking whether the fence is strong enough to prevent the wild ducks from fleeing. The sky net of the duck farm should be more than 2 meters away from the water in order to drive and capture. 6. Select and stay: After 70 days of age, leave the male to female ratio 1:6. The average daily feed consumption of ducks is 103 grams. During the laying period, attention should be paid to the balance of protein and calcium and phosphorus in the feed, or fed exclusively from ducks and ducks in order to achieve high and stable yields. In the duck housing, there must be egg production areas, clean hay, and train ducks to lay eggs in the egg production area. Pay attention to ensure the cleanliness of eggs to facilitate hatching. Third, the disease prevention and control of wild ducks can not be grazing, can only be raised around the net, in order to facilitate the prevention of epidemic. However, attention should be paid to ensuring that the water quality is fresh and avoiding excessive breeding density, otherwise a large number of duck droppings will accumulate at the bottom of the pond, causing water quality corruption and inducing clostridin poisoning. Wild ducks have fewer diseases, but they should be aware of duck dumplings. Vaccine against duck gizzards may be vaccinated from time to time depending on local prevalence.
