Compared with grazing and ground level raising, net-meat duck has the advantages of saving labor hours, saving materials, and reducing the spread of diseases, and has obvious economic benefits. The technical measures of net duck rearing mainly include the following points:
First, the main confinement, to create a continuous feeding feeding. The net-raising ducks do not have sports grounds, grazing lands, and do not need to be littered. They are kept in the sheds throughout the period. Conditional breeding can be carried out in the early stages, and the rearing period can be combined with feeding. However, it is necessary to ensure that the ducks can continuously drink water, eat food and sewage. In order to play the advantages of high-quality meat duck growth, high survival rate, less material consumption.
Second, rebuild the ground conditions for duck shelters. The net raises the duck to use the existing duck house mainly, the idle pig house, the chicken house can also, require its structure is good, the ground level is smooth.
Third, the reconstruction method. The ground requires a certain degree of slope, preferably cement or brick concrete floor, with a drainage ditch, and a sewage pool outside. 40 to 50 centimeters from the ground at the place of horizontal shelves, horizontal shelf spacing of 1 to 3 meters, the width of the shed to determine the width of the crossbar. The prefabricated rectangular bamboo block (12 meters) is laid on a horizontal shelf. The width of the bamboo fence is 2 to 3 centimeters and the spacing is 2 to 2.5 centimeters. After the meat duck was 0 to 14 days old and 15 days old, a plastic net of 1735 mm and 2040 mm mesh size was laid on the bamboo fence, and the plastic net splicing was fixed with a bamboo strip. The use of 1,525,300 mm prefabricated plastic water pipes to transform the semi-automatic drinking trough, placed against the wall, 5 to 10 cm above the ground. The meat duck uses a 20507 cm rectangular feeder trough at the age of 1 to 4 days, each duckling has a feeding position of 1.4 centimeters; the meat duck uses a rectangular manger of 2,56010 centimeters or a plastic circular bowl of 50 centimeters in diameter at 15 to 50 days of age. , Bamboo liners are placed below to prevent feed spreading. The breeding density of meat ducks at the age of 1 to 7 days is 15 birds per square meter, and the suitable breeding temperature is 27°C to 30°C. The breeding density of meat ducks at 6 to 21 days is 10 birds per square meter, which is suitable for rearing. The temperature is 25°C to 27°C; the rearing density of meat ducks from 22 to 50 days is 5 to 6 per square meter, and the appropriate rearing temperature is about 20°C.
Fourth, the use of full-priced pellet feed. Meat ducks used 1 to 21 days of age with a pellet feed of 3 mm in diameter. After 21 days of age, meat ducks were fed a pellet feed of 5 to 6 mm in diameter for free feeding. The water tank was cleaned once a day and the drinking water supply was sufficient. The nutritional level of the diet of duck fed within 3 weeks of age was crude protein 16%, crude fiber 6%, crude ash 6%, calcium 0.6%-1.2%, and phosphorus 0.46%; meat ducks after 4 weeks of age were supplied The nutritional level of the diet was crude protein 16%, crude fiber 6%, crude ash 6%, calcium 0.6% to 1.2%, and phosphorus 0.44%.
