Autumn forage is abundant and the temperature is suitable. It is the golden season for ducks. In recent years, the meat duck industry has developed rapidly in China, and it has gradually formed a one-stop industrial development pattern of gathering ducks, hatching, feed, processing and sales, and has played an important role in stimulating farmers' income. This edition edits a group of practical techniques for raising ducks for reference by farmers.
Autumn ducks should pay attention to the following basic principles: First, select ducklings. It is necessary to choose ducklings that are clean and dry, lively and lustrous, have soft and shiny fetal hair, eat fast and many, and are loud and loud.
The second is to start good food. The ducklings bought back were first fried with 50 grams of Coptis and 250 grams of licorice. The mixture was fed to 100 ducklings. Then 0.5 kg of mung bean and 0.1 kg of gypsum were mixed in 10 kg of rice and fed for 3 to 5 days. Give ducklings brown sugar water or honey water. Ducklings should not rush into the water within 7 days. Do not allow ducks to move in places where the temperature exceeds 32°C. Instead, ducks should be allowed to rest in the shade, such as in the woods and on the creeks, and they must not be allowed to get together. After the start of eating, the ducklings are fed with half-cooked rice and cold water. Feed 5 to 7 times a day. Half of the meal is fed each day. After 5 days, lightly salted water is given. After 7 days, before 10 a.m. and 6 p.m., The ducks were rushed into the shallow water and trained 15 minutes each time. In the past 20 days, some green feed such as duckweed was fed. After 20 days, the ducklings can gradually reduce the number and quantity of feeding when they can find food on their own. They can salvage some feces and worms and feed them. After 30 days, they can drive into rice fields and rivers.
The third is to strengthen ventilation. Keep the air circulation in the duck house, fresh and cool, such as the hot weather at night, the ducks screaming uneasy, you can rush the ducks into the pool water, ventilation can also be used electric fans.
Fourth, feed preparation. Miao ducks are raised to normal feeding after 7 days of age. The feed mix was 38% corn, 12% bran, 25% soybean cake, 3% fishmeal, 20% shellfish, 1.5% bone meal, 0.5% salt, 11.72 to 12.4 MJ of metabolic energy per kilogram of feed, and 18% to 19% of crude protein. %. Feeding once every 3 hours after hatching 1 week; feeding 3 to 4 times daily after 20 days of age, and can use paddy field stocking to reduce the amount of materials used.
The fifth is scientific grazing. Scientific grazing can save feed and should be "three to five, not five." “Three accomplishes†means that ducks should be trained “on the rods†a few days before the ducks are ducked; ducks should be fed with suitable feeds to avoid swallowing too much silt due to hunger and greed; water and water should be selected. Grazing in many places, grazing time should grow from near to far with the age of the duck, at noon to rest more in the shade, and always swim and drink, so that early animal husbandry late harvest. "Five-freezing" means not ploughing fields or walking hot roads for grazing; grazing less than pesticide-contaminated land; preventing ducks from flapping their wings and avoiding frightened wounds of ducks; grazing without water, water retreating, water escaping; Grazing under the hot sun.
The sixth is to strengthen insulation. At the end of October, we must do a good job of preventing cold winds from attacking. When stocking, we should rush to warmer sandy beaches, ponds, canals and other shelters to avoid cold weather.
Seven is the intensity of fattening. The fall duck can grow to 1 to 1.2 kg when it is raised for 50 to 60 days. At this time, it can be quickly filled with a “high energy and low protein†compound feed.
Eighth, prevention and control of epidemics. Autumn ducks are prone to big head lice. The mortality rate is as high as 90%. Therefore, we should diligently sweep the duck dung and wash the feed tanks; keep the duck houses dry and ventilated; use 10% to 29% fresh lime solution to disinfect; regularly inject duck dumplings, poultry outbreaks, etc. to immunize; Weekly feeding of oxytetracycline for livestock was conducted at a dosage of 500 grams of oxytetracycline per 50 kg feed. Suspicious ducks and presumed healthy ducks were vaccinated with duck gizzard vaccine, strictly sterilized, and treated as early as possible. Use 250 grams of butter, 120 grams of pepper and garlic, mix and feed 80 ducks, or fry 1 kilogram of barley, heat it in the cylinder, and then use a rabbit's blood to mix the fried wheat duck. Within 24 hours after feeding, ducks are forbidden to go into the water and draught, which is very effective in preventing and curing diseases.
