High-yield feeding techniques for laying ducks

With abundant forage and suitable temperature in autumn, it is the golden season for raising ducks. In recent years, the meat duck industry has developed rapidly in China, and has gradually formed an one-stop industrial development pattern of duck breeding, hatching, feed, processing and marketing, which has played an important role in increasing farmers' income. This issue compiles a set of practical techniques for raising ducks for farmers' reference.

The following basic principles should be paid attention to in raising ducks in autumn:

??? One is to choose duck seedlings. Choose ducklings with large size, clean and dry navel, lively and lively, soft and shiny fetal hair, fast eating and loud calls.

The second is to open up a good diet. The bought duck seedlings were first fried with 50 grams of Coptis chinensis and 250 grams of licorice for 100 ducklings, then mixed with 0.5 kg of mung beans and 0.1 kg of gypsum into 10 kg of rice for 3 days. Ducklings are often given brown sugar water or glucose water and honey water. Ducklings should not rush into the water within 7 days, do not allow ducks to move in places where the temperature is more than 32 ℃, but should rest in shady places such as woods and streams, and do not let them gather together. After eating, the ducklings were fed with half-cooked rice and cold water, five to seven times a day, each time half full, and five days later, light salt water was rationed. Seven days later, before 10:00 and after 6pm, the ducklings were trained in shallow water for 15 minutes at a time. For 20 days, they were also fed with some green feed such as duckweed every day. After 20 days, when the ducklings can find their own food, the number and number of feeding can be gradually reduced, some dung maggots and worms can be salvaged and fed, and after 30 days, they can be released into rice fields, streams and rivers.

The third is to strengthen ventilation. To ensure that the duck house is well-ventilated, fresh and cool, such as the muggy weather at night and the uneasy singing of the ducks, you can drive the ducks into the pool water or use electric fans for ventilation.

Fourth, feed preparation. The young ducks can be transferred to normal feeding after being raised to 7 days old. The feed mix is corn 38%, bran 12%, bean cake 25%, fish meal 3%, shell 20%, bone meal 1.5%, salt 0.5%. Each kilogram of feed contains 11.72-12.4 megajoules of metabolic energy and 18%-19% crude protein. Feed once every 3 hours after the first week of shelling, 3-4 times a day after 20 days of age, and can be stocked in paddy fields to reduce material consumption.

Fifth, scientific grazing. Scientific grazing can save feed, which should be "done three times and not released five times". The "three attainment" means that ducks should be trained to "get on the pole" a few days before duck stocking; proper feed should be given to drive ducks out of grazing so as not to swallow too much sediment due to hunger and greediness; grazing in places with shallow water and clear grass should be chosen, and grazing time should go from near to far with the increase of duck age, rest in the shade at noon, and swim and drink water at any time, so as to get grazing early and late. The "five not releasing" means not going down the fields or hot roads on the way to grazing; grazing in areas contaminated by pesticides; not allowing ducks to flapping their wings to avoid being frightened and injured; not grazing against the current, releasing the water and rushing back when the water rises; and not grazing in the hot sun.

The sixth is to strengthen thermal insulation. From the end of October to do a good job of cold wind attack, stocking should be rushed to warmer beaches, ponds, canals and other shelter, in order to avoid cold and cold.

Seventh, intensity fattening. Autumn ducks can grow to 1-1.2 kg when they are raised for 50-60 days, and then they can be quickly fattened with "high-energy and low-protein" formula feed.

Eighth, the prevention and control of epidemic diseases. Autumn ducks are prone to big head plague, with a mortality rate of more than 90%. Therefore, duck droppings should be swept frequently, feeding tanks should be washed frequently, duck houses should be kept dry and ventilated, 10%-29% fresh lime solution should be used for disinfection, duck plague, poultry failure and other epidemic (bacterial) vaccines should be injected regularly, and livestock oxytetracycline should be fed once a week. 500 grams of oxytetracycline is mixed every 50 kg of feed. Duck plague vaccine was used for emergency vaccination, strict disinfection, early isolation and early treatment for suspected ducks and presumed healthy ducks. You can feed 80 ducks with 250 grams of butter, 120 grams of chili peppers and 120 grams of garlic, or stir-fry 1 kg of barley and put it into a tank while it is hot, and then feed the ducks with the blood of a rabbit mixed with fried wheat. Within 24 hours after feeding, the ducks are prohibited from entering and draining, which is very effective in the prevention and control of epidemic diseases.
