Weishan Ma duck is a smaller egg and meat variety. It is mainly produced in Nansi Lake (Nanyang Lake, Dushan Lake, Zhaoyang Lake, Weishan Lake) in the territory of Guangdong Province and along the Grand Canal along the north, and Weishan County and Jining City as the central production areas. The “Dragon Eggs†used for processing of Weishan Ma duck eggs are delicious because of their high quality and are exported to North America, Japan, etc. (A) The environmental conditions during the brooding period are based on the brooding season and the amount of feeding. In two ways, freshly hatched ducklings weigh between 48 and 55 grams, suitable brooding temperature between 0 and 4 days is 28 to 30°C, and then fall 3-4°C per week until it falls to 15°C, the temperature difference between day and night. Within 3C, the relative humidity is controlled between 60% and 70%, and the air is kept fresh, and the first week of age is only 23 days per day, and then decreases gradually. After 3 weeks of age, it is natural illumination, and the lighting is turned on overnight. When there is a habit of getting together (especially in dark, low-temperature environment or when frightened), the ducklings should be prevented from being heated or stepped on.(2) The “opening†time for drinking water at different times and in different seasons is different. (10) 24 hours after the shell, 18 to 20 hours after hatching of the duck, and 14 to 28 hours after the hatchling comes out of the shell. After drinking water first, “eat foodâ€, and feed less frequently, mainly based on millet and batch materials. Feed 6 to 8 times. After 3 days of age, you can “clamâ€, that is, add fresh cooked small fish shrimp into the feed. , Snail meat and other animal protein feed, at the same time feeding green feed for “open green.†Ducklings have the habit of drinking water while eating materials, each feeding should maintain sufficient drinking water. After 5 days of feeding, if the weather is fine and the temperature is suitable, then you can train ducklings into the water in the town, and then you can lay a plastic film on the outside and pour water into the raised towel on the four sides. The depth of water is about 2 cm, and then put in water and then put it in temperature. When the ducklings are in the water, the ducklings are used to getting into the water after several days.After the water is poured, they should be feathered in a place where there is no wind and warm, so that the wet hair on the body can be dried as soon as possible, and wet hairs must not be brought into the brooding. Take a rest.The ducklings should put shallow water in the water first, time is 30 minutes, increase the watering time and deepen the water level as the age increases, but it is necessary to control according to the changes of the weather to prevent the ducklings from getting cold.(4) Training and grazing ducklings 3 Grazing can be done after the age of the grazing, the grazing distance is from near to far, the number is from less to more, and the time is from short to long. When the grazing is started, attention should be paid to changes in the weather, and the grazing times and times should be flexibly controlled. Create a clean living environment The litter should be replaced frequently, and salt and drinking equipment should be cleaned and disinfected every day, and ducks should be regularly disinfected both inside and outside, and at the same time, prevention of diseases such as duck hepatitis, serositis and duck gizzards should be carried out. And whether the analysis of survival rate status management is appropriate, such as 1-7 days of fluffy yellow, 8-15 days of age, fluff color from yellow to white, elongated body called "Jiao Luoguo", 16-20 days old back with a black feather began The growth is called “Daluguo†and the feathers on the two ribs of the head and tail between the ages of 21 and 30 are called “four sides of red.†The body weight on 30 days is 900 grams, and the survival string is more than 95%.
