First, scientific choice of feed All kinds of nutrients needed during the growth period of young ducks must be satisfied. Feeds should be diversified to maintain energy and protein balance. The protein in the diet should not be too high and the calcium content should be appropriate. In the production, depending on the growth and development of ducks, the necessary nutrients should be increased or decreased as appropriate. Such as Shaoxing duck, the normal opening date of production is 130-150 days, the opening weight of 1400-1500 grams, if the weight exceeds 1500 grams, should limit feeding, feed more appropriate green feed and roughage; poor development, light weight Ducks, appropriately improve the quality of feed, each feed about 150 grams per day, plus a small amount of animal fresh feed. All the young ducks use mixed feeds. Add appropriate amount of fresh water before feeding and mix them with wet materials to feed. Feed 3-4 times a day at equal intervals. Second, the management points 1. Appropriately strengthen exercise, promote bone and muscle development, prevent excessive fat. Drive regularly every day to make it move in a circle, every 5-10 minutes, 2-4 times a day. 2. More contact with ducks to increase the guts of ducks and prevent frightening groups. 3. Shelter lights all night, low light lighting. The standard daylight hours for young ducks are 8-10 hours per day and should not be increased before the start of production. In order to facilitate the ducks to drink at night, to prevent the rats from harassing and disturbing the group, the house should be illuminated with low-light lighting. A 30-watt light bulb can be installed on a 30-square-meter duck house. If a blackout occurs, the kerosene lamp should be turned on immediately. 4. To strengthen the prevention of infectious diseases. 5. To establish a stable system of work and rest. According to the living habits of ducks, a routine system and operating procedures should be established to maintain stability after the formation.
