Techniques for raising wild ducks

1. Artificial hatching method of wild duck

Small-scale breeding of wild ducks, the use of traditional hatching methods, large-scale breeding of wild ducks, generally need to buy computer-controlled automatic hatching facilities. Before hatching, the breeding eggs with high fertilization rate were selected, cleaned and sterilized, and the egg code plate was sent to the hatchery for hatching. There are two methods for the hatching of wild ducks: constant temperature management and variable temperature management.

The constant temperature management maintained a temperature of 37.2 ℃ in 1-26 days and 37 ℃ in the hatching period. The temperature change management maintained 37.5-38 ℃ in 1-15 days, 37-37.5 ℃ in 16-25 days, and 37 in 26-28 days. C .

The hatching of breeding eggs needs a certain amount of humidity, 70% relative humidity for 1-8 days, 60%-65% for 9-21 days and 70% for hatching.

During the incubation of wild ducks, proper ventilation should be carried out to ensure that the breeding eggs can get enough oxygen and maintain the normal metabolism of the breeding eggs. In the process of hatching, the eggs should be turned frequently to keep the eggs heated evenly and evenly. Turn eggs 10 times a day for 12 times a day from 1 to 21 days, turning eggs at an angle of plus or minus 45 degrees. After 22 days, they rush to stand for 8 times a day. In order to reduce the temperature of breeding eggs, open the door, fan or spray cold water were used to dry the eggs in the middle and later stage of hatching. The eggs were dried twice a day for 13 days, 2 times a day for 14 days, 3 times a day for 26 days, and 3 times a day for 4 times a day.

2. Feeding and management of ducklings

The artificial breeding of wild ducks can be divided into two forms: shed breeding and grazing breeding. Shed breeding choose a place close to the water source to build a duck house, the duck house should have a playground and a pool, and the whole duck house should be covered with a nylon net, which is about 5 meters high. Grazing feeding, in the case of large water surface, domesticated wild ducks find food by themselves during the day and return home automatically at night.

The body temperature of newborn ducklings is 30c lower than that of adult ducklings, and their own temperature regulation ability is low. the temperature control and heat preservation of ducklings is the key to the success or failure of ducklings. The indoor temperature of brooding was maintained at 30 ℃ in winter and spring, and then decreased loc every 2 days. After 20 days of age, the room temperature management could be gradually transferred to normal temperature management. The relative humidity of the brooding room is controlled at about 70%. Too high and too low are not conducive to the growth of wild ducks. The suitable density of 10-day-old ducklings is 40 ducklings per square meter, 30 ducklings at 11-20 days old and 25 ducklings at 21-30 days old. The weather is sunny and can be put out for activities after 20 days of age.

After the newborn ducklings enter the human rearing room, they will drink 5%-8% glucose water, and then supply 200 mg / kg potassium permanganate solution at intervals of 3 days. The ducklings can be raised after 3 hours of drinking water. The ducklings are fed with digestible soft feed, and the ducklings are fed with formula feed after 3 days. The rats were fed 7 times a day before 10 days old, including 2 times at night, 5 times a day at the age of Ii~20, including 1 time at night, and 4 times a day after 21 days of age.

During the feeding period, the ducklings should also be ventilated regularly to keep the air in the duck house clean. The growth of ducklings needed a certain amount of light, day and night light was carried out within 10 days old, night light time was gradually reduced at 11-20 days old, and transition to natural light after 21 days old.

3. Management of wild ducks during breeding period

The wild duck at the age of 31 to 160 days is the wild duck in the breeding stage.

The breeding period is the period of the fastest growth and development of wild ducks. generally speaking, 60-day-old wild ducks are close to adult ducks in terms of body weight and shape, so they should be sold in time when raising meat wild ducks. Wild ducks that lay eggs should continue to be fed. Adult wild ducks have a strong ability to fly. The adult duck house is different from the duckling house. The whole duck house should be closed with a nylon net. The size of the bred ducks is relatively large, with a feeding density of 10 × 15 ducks per square meter. Bred ducks grow fast and should be fed with full-price feed three times a day, with a daily feed dose of about 5% of their body weight, and about 15% chopped green feed is added to the feed to ensure the supply of vitamins. Adult ducks have a large amount of feces, so the duck house should be cleaned regularly to keep it clean and hygienic. Drinking water should be kept clean. For example, the water in the duck pond should be changed frequently. Timely epidemic prevention, timely isolation and treatment of diseased ducks.

4. Breeding of laying ducks

Wild ducks reach the age of laying eggs when they are raised for about 170 days. There is a large amount of protein in the feed of laying wild ducks. Sufficient protein should be added to the feed, the amount of bone meal and shell powder should be increased, and the feeding times should be increased to 4 times a day. During the laying period, keep sufficient light, the whole day light time is not less than 15 hours, every morning and evening for 2-3 hours of artificial light. As the mother duck is used to laying eggs in the mud with recesses, it is possible to consciously make some egg-laying nests on the ground and spread some grass on it. Most female ducks lay eggs at night, but a few lay eggs in the morning, so the time to open the shed every day should not be early, in case the eggs can not be picked up outside.
