Duck duck high-yield and high-efficiency feeding technology (I)
The price of duck eggs has recently risen, and farm production of breeding ducks has increased. Allowing the majority of farmers to master the new technology of high-yielding breeding of ducks and ducks is the key to obtaining successful breeding and producing better economic benefits.
1. Use fine varieties. The excellent duck breeds with an annual output of 250-300 eggs include: Shaoxing duck (for breeding, grazing), Jiangnan No. 1 and Jiangnan No. 2 (for captive breeding), Lixian Ma duck (for grazing), Putian black duck (for soft , hard beach feeding) and schneidered ducks (appropriate for altitudes from 800 to 1200m).
2. Site selection and building. Away from towns and poultry trading areas, there is no pollution of the soil and water sources, and other polluted ponds, reservoirs, and streams with slow water flow are suitable for building ducks. The soil on the duck farm site should be breathable and permeable. It is best to use sandy soil. It is also necessary to shelter from the wind and maintain a gentle slope of approximately 5 degrees with the water surface. The duck house has a practical area of ​​6-8 feathers per square meter, and it is better to keep 900-1000 feathers per house. The duck house is made of bamboo and wood, with a width of 8 to 10 meters, a length of 70 meters or less, and a height of 2 to 2.5 meters. It has a high degree of self-determination. It is hung with a straw curtain to the roof of the house, and is covered with a transparent plastic film to block the wind. There are three 60W electric lamps and two 15W lamps per 100 square meters of space. There should be a playground that is dry, slightly sloping but flat and about 2 times larger than the duck house. The duck's water playground should be more than 3 times larger than the duck's house and be surrounded by nets or bamboo fences.
3. Ducklings feeding and management. Ducks and ducks are best to raise "spring ducks" in mid-May to mid-May. They can also raise "spring ducks" in June or "autumn ducks" in August.
Ducklings should be opened and eaten within 24 hours. Usually drinking water first and then eating. For the first 3 to 5 days, it is best to allow the duck to drink cold boiled water or pure water, plus 1% to 2% glucose in water. After drinking water, feed rice cooked with half-cooked rice (if you mix in 10% glucose water, 10% leeks are better). After 3 days, 10% to 20% of the weight of the feed is fed with chopped screw, shrimp, clam, and other animal feed, and 5% of the fish meal can also be used instead. From the third day, 10% to 20% chopped green fodder should be added to drinking water, or water grass, duckweed, etc. should be fed on the water. The first 3 days of eating should be properly controlled food intake, only let young ducks eat 7 to 8 percent full, 3 days after the release of feeding, each time let the ducks eat. Ducklings within 10 days of age were fed 6 times a day and night (3 times during the day and 3 times in the evening). Ducklings aged from 11 to 20 days were fed 4 to 5 times a day and night (3 times during the day, 2 times during the night, or 4 during the day. Times, 1 time in the evening, depending on the duck's feeding situation. Within 15 days of age, ducklings should be prevented from getting up late. When the ducklings are long, they must be reared in groups of 300 to 400 birds per group.
