The survival rate of ducklings directly affects the economic benefits of ducklings. The following nine measures should be taken to improve the survival rate of young ducklings.
First, pick young children seriously. Choose eye and spirit, lively, well-balanced, well-trimmed, shiny, hair-enclosed body, soft abdomen, no blood or lump at the umbilical cord, big head, wide back, wide open, sound-clearing Caged.
Second, the density should be appropriate. Each group of ducks is suitable for 500. Within the age of 7 days, 60 to 65 birds per square metre were housed, 40 to 45 for 7 to 15 days, and 15 to 18 for 15 days.
Third, the temperature should be appropriate. Ducklings after hatching have short fluff and poor ability to regulate body temperature. If the temperature is not adjusted, the survival rate will be affected. The temperature requirements of the ducklings on cages are: 1 to 2 days of age 30 to 29°C, 3 to 7 days of age 29 to 24°C, 8 to 10 days of age 24 to 19°C, 15 to 21 days of age 19°C ~ 17 °C, after 21 days of age can be maintained at 15 °C, the temperature difference can not exceed 4 °C per day, gradually reduce the temperature at return to room temperature.
Fourth, the air should be fresh. Duckling metabolism is strong and requires fresh air. Therefore, while controlling the temperature, it is also necessary to ensure the circulation of air in the house. It is best to install a ventilation fan on the window, but to prevent the thief from blowing the duck body.
Fifth, light should be moderate. Moderate illumination not only facilitates duckling feeding, drinking, and activities, but also promotes the growth and development of ducklings. The method is: a 10-watt bulb can be installed in each brooding room, full daylight is used for the first 3 days, and then it is reduced by 2 to 3 hours each week to restore natural light at 4 weeks of age.
Six, open food to be timely. When the ducklings get out of the shell 20-30 hours later, when they hear the sound, they stand up and open their heads to open their mouths. Drink water first, then feed. For the first time, drinking water should be formulated with a small amount of potassium permanganate, the concentration of which turns red in water, and the hand reaches into the water to see the degree of fingerprinting, in order to facilitate the excretion of meconium. After cooking, cook half-cooked rice in a timely manner, immerse in clean water, remove stickiness, mix in 1.5%-2% white sugar, and let ducklings feed on the trough. On the day of eating, feed it once every 1.5 to 2 hours, and feed 80% of them each time to prevent bulging.
Seven, nutrition should be reasonable. From the second day of eating to the fourth day, drinking water and feeding 5 to 6 times a day. 5 to 15 days of drinking 4 to 5 times, 15 days after 3 to 4 times a day. The feed is still cooked with half-cooked rice, but from the 4th day onwards, add no sugar, change to feed compound feed, and add some green feed. After the 10th day, it is best not to feed in the evening, and hot water can be added once in hot weather.
VIII. Do not ignore the release of water. The ducklings can be put into the water for 5 to 7 minutes after being hatched for 2 to 5 days. Wet the feet first, then sink slowly and let them swim and play. Afterwards, we will release water regularly every day. After 7 days, it can be placed in shallow water 8 to 10 cm deep for 15 to 20 minutes each time after feeding; after 15 days, the water depth in the enclosure is increased to 15 to 20 cm, and each time the water is released for 20 to 30 minutes.
Nine, disease prevention should pay attention. Ducklings were diluted 15 days at the age of 15 days with 0.5-mL dilution of duck plague attenuated vaccine and 0.5 mL per intramuscular injection; 20-day-old ducks were injected with 2 mL of aluminum hydroxide bacterins per breast muscle. Usually pay special attention to ducklings soft foot disease; use the compound sulfamethoxazole 0.5% of the proportion of feed, even feed 3 to 5 days, stop 10 days before feeding 1 to 2 courses, can effectively prevent coccidiosis and dysentery disease.
