The Chaohu duck, also known as the Chaohu Ma duck, is a local variety that is popular among consumers because it is a production area in Qijiang County. This kind of duck egg is also used. It is thin, tender and tender, with thin bones. It is good for both farmers and food lovers.
Chaohu duck breeding building requirements. Select soil permeability is good, slope in the 5-10 degrees, sunny backyard venue, the site should be flat to prevent accumulation of water. The construction site should be oriented towards the south and south. The location of the duck house should be on the north side of the water surface, and the duck beach and water sports area should be placed on the south side of the duck house so that the gate of the duck house is facing the water and face southwards. This kind of oriented duck house has a large lighting area in the winter and absorbs light. The heat insulation is good; in the summer, it is not exposed to direct sunlight and is well ventilated. It has the characteristics of being warm in winter and cool in summer, and is beneficial to the egg production and growth of ducks.
For the management of Chaohu duck breeding period, 5 to 10 weeks old ducks have enhanced digestive capacity, large feed intake, and resistance to roughage. In addition to increasing the total amount of feed daily, they should also supplement green feed such as grasses and vegetables. The green feed mainly comes from the cultivation of artificial forage grasses, and can be used for grasses, purple lilies, etc., and when the fattening reaches 10 weeks of age, the ducks weigh 3.5 to 4 kg and the female ducks 1.5 to 2 kg. In management, ducks and mothers should be reared separately, and each group should have 100 to 300 animals, and 5 to 8 can be raised per square meter. Ducks begin to moult at this stage and are prone to warts. Attention should be paid to breaking and shading. A large group of breeders also need only a small area of ​​pool or basin for drinking, but must pay attention to the cleanliness of drinking water, and can not be interrupted. During the breeding period, young ducks do not need too much protein in their diets, and their calcium content must also be suitable. Since breeding ducks have not yet established a perfect feeding standard, depending on the specific conditions of growth and development, it is necessary to increase or decrease the necessary nutrients. Such as egg-type varieties, the normal opening date is 130 days to 150 days, the standard opening weight of 1400 grams to 1500 grams. If the weight exceeds 1500 grams, it is considered too large, and the feed should be lightly limited, and more green feed and roughage should be added. For poorly developed and light-weight ducks, the amount of feeding should be appropriately increased, and the average daily feed should be about 150 grams per day. In addition, add a small amount of animal fresh feed, feeding 3 times to 4 times a day. The interval between feedings should be as equal as possible to avoid food inequality during feeding.
The management details of the captive, the duck house should be cleaned and regularly sterilized. The duck house should be cool in winter, cool in summer, well ventilated and kept clean and dry. Drinking utensils and drinking fountains should be cleaned once a day, and duck houses are regularly sterilized. Appropriately strengthen the exercise, promote the development of duck bones and muscles, prevent excessive fat. Every day, the ducks are rushed to exercise in the house, each time for 5 minutes to 8 minutes, 2 times to 3 times a day. Conditions can be used for short-distance, short-term grazing. More contact with ducks, raise the guts of ducks and prevent frightening herds. The ducklings of the young ducklings are small, and the eggs are particularly sensitive to breeder nerves. Should use feeding, water feeding, grass exchange and other opportunities to contact more ducks, consciously raise the guts of ducks, so as to avoid being approached by strangers or when the environment changes, causing alarm and causing serious losses.
Chaohu duck breeding should strengthen the prevention of infectious diseases. There are two main infectious diseases of young ducks: cholera and duck plague. The general immunization procedure is: 60 days old to 70 days old injection of avian cholera vaccine, 100 days before the next injection of a bird flu vaccine, 70 days to 80 days old injection duck plague vaccine. For ducks that have only 1 year of feeding, they can be injected once, once every 2 years, and once a year.
