Autumn duck rearing technology
Generally, duck farmers are accustomed to rearing early spring ducks. In fact, raising autumn ducks can also achieve more significant economic benefits. Xu Lihan, a professional duck producer at Wangzhuang Village, Xinlin Township, Fanchang County, Anhui Province, has been using the local natural advantages to raise autumn ducks since 1999. In the past three years, the scale of breeding has continued to expand and the benefits have been increasing year by year. From 1999 to 2001, he raised 150 ducks, 256 ducks and 400 ducks respectively, and earned net profit of 706 yuan, 1,325 yuan, and 2,200 yuan. The characteristics of raising autumn ducks: First, the climate is suitable. About 10 days after the fall into the brooding, the survival rate of up to 98%, raised to 60 days or so, weighing up to 1.5-2 kg, and ducks easier to manage. The second is to save feed. Autumn ducklings can eat falling valleys and insects in one season rice field and double rice field. Since then, grazing can be conducted at lake beaches, ponds and ditches to allow young ducks to feed on natural animal and plant feeds. This will not only facilitate the removal of insects, seedlings, and ventilation in paddy fields, but also that the ducks will grow particularly fast and shorten the feeding cycle. . Of course, feeding ducks has its specific conditions. The central task of the duck feeding and management in the early period was to prevent heatstroke and reduce appetite. In the later period, due to the gradual decrease in temperature, it was necessary to do a good job of preventing cold and warming. First, strengthen ventilation. Keep the air circulation in the duck house and keep it fresh and cool. If the night is hot and the ducks are howling, the ducks can be driven into the pool water. Conditional farmers can use electric fans for ventilation. Second, increase the awning. In the early fall, due to the high temperature and temperature, try to put the ducks early and return home late. At noon the hot rush to the awning or a tree to rest and cool, reduce heat radiation. Dry heat at noon can be sprayed into the shed, duck body cooling water to prevent heatstroke. Third, pay attention to the preparation of feed and feeding. Ducklings are raised to normal feeding after 7 days of age. The proportion of feed is (%): corn 38, sub-flour 20, bran 10, soybean cake 25, fish meal 3, shell powder 2, bone meal 1.5, salt 0.5, and the amount of a variety of vitamins. Within 24 hours of the first week of shelling, water and material were continuously fed to allow them to feed freely; 1 feeding every 3 hours after 1 week; 3 to 4 feedings per day after 20 days of age and grazing using paddy fields. Reduce the amount of material used. Fourth, strengthen insulation. From the end of October, it is necessary to do a good job of cold insulation work, and the places around the duck houses should be tightly closed to prevent thieves from invading. During grazing, the ducks are rushed to the relatively warm river beach, ponds, and drainage canals where they are sheltered from the wind and sun exposure. Fifth, strengthen prevention. Always check the temperature in the house to observe the diet, defecation, and activity of the ducklings. Wash the water dispenser frequently to ensure adequate and clean drinking water. Always change the bedding or use sand instead. This will not only have good permeability but also prevent the growth of parasites and bacteria. In addition, care should be taken to prevent colds caused by abrupt changes in the weather. Compounds such as entomogenin, oxytetracycline, and vitamins can be added to the feed to prevent diseases. Once the duck has developed, it should be treated immediately and the sick duck should be kept in isolation.
