First, the choice of species. Duck ducks suitable for fast fattening include Cherry Valley Duck, Beijing Duck, Kangbei Duck, Jianchang Duck and Shanghai White Duck. These breeds of ducks are tame, hi gregarious, strong in cold resistance, fast in growth and development, good in fattening performance, high in slaughter rate, tender and tasty, and suitable for feeding in quick-moisturizers.
Second, young chicks. Ducklings are called young chicks from the hatching to 20-25 days of age. The purpose of nurturing young chicks is to ensure that the survival rate reaches more than 90%, so as to facilitate the breeding of large-size and robust ducklings, laying a good foundation for the young chicks.
1, choose young. Fluffy bright and cover the navel. The abdomen is soft and elastic, the anus is clean, the legs are thick, the mouth is large, and the eyes are divine. The body is well-balanced and healthy.
2, insulation. Within 7 days after hatching, the ducklings should be kept at 27-30°C. After 7 days, the temperature can be lowered by 1°C per day. After 15 days, the ducklings are kept at about 15°C. After 20 days, they are kept at room temperature. If the temperature is low during the early brooding period, the short straw can be laid in the basket to make a flat bottom nest. Place 10-20 kittens per basket, cover the old clothes, and cover them (pay attention to breathability), so that the ducklings can rely on each other to keep warm.
3, open food. Before drinking, drink water. The water temperature is about 20°C. For the first time drinking water, 0.04% potassium permanganate should be added to the water. Feed it once every 1.5-2 hours, and feed only 80% of the full weight. Use cooked boiled rice and soaked in clean water to remove stickiness. After draining, mix in 1.5% to 2% of white sugar to allow ducklings to eat and eat while spreading, 2 times a day.
4, put the water, ducklings out of the shell 2-5 days after the use of leaky screened ducks into the water 5 to 7 minutes, first wet feet and then slowly sinking, let it swim. 7 days before the release of water 2-3 times a day, each time 10 to 20 minutes; 7 days after the end of each feeding the duck into the shallow pool of 8 to 10 cm deep, 15 days later, the depth of the pool increased to 15-20 cm.
Third, feeding ducks. Ducks are called ducks at this stage of 50-65 days. Its requirements for bred are: to ensure its nutrient supply, give full play to the advantages of fast growth and development of meat ducks at this stage, and give priority to feeding. Supplementation with grazing, rearing in groups, and the principle of reducing the amount of feed in order to make it thicker and thicker.
1, house feeding. Suitable for large varieties of white feathers such as Cherry Valley Duck and Beijing Duck. The venue can be selected to be next to Tangku or Hewan. The pens should be air circulated. A 60cm tall duck bar with 5m2 can be placed in bamboo strips and 20-30 ducks can be raised. -100, separated by fences. In the column on the sidewalk side, a trough and a sink are installed. Ducks account for 35%-40% of feedstuffs for bran and 40%-45% for cereals. Its formula is: corn 62%, wheat bran 15%, fried pea 6%, fish meal, rapeseed cake 7%, bone meal 2.8%, salt 0.2%. Feed 4 times a day. Supply water while feeding, and add green material at the same time. The proportion of the general green material and compound feed is 1 to 1.5:1. In addition, it is necessary to strengthen the bathing of grazing ducks in house feeding, and grazing for 1 hour each day before 11 o'clock in the morning and after 4 o'clock in the afternoon.
2, grazing bred. Applicable to Jianchang duck, Gaoyou duck and other varieties of duck. Can be placed in winter waters, rice fields, ponds, creeks and other waters. The grazing time is generally 1 in the past and 1 at the same time, and feed the compound feed 2-3 times a day. Its feed formula is: corn 35%, wheat 16%, wheat bran 23%, fried Hu bean 5%, rapeseed cake 7%, cocoon 7%, rice bran 4%, bone meal 2.7%, salt 0.3%.
Fourth, the intensity of fattening. In order to shorten the feeding period of meat ducks, promote early slaughter and increase the fatness of meat ducks, the meat ducks are delicious and tender. The ducks are raised to the 50th to the 65th day, have a certain skeleton and muscles, and grow fastest. It is necessary to implement the intensity of fattening. High-energy, low-protein compound feeds should be used during fattening. The reference formula is: 35% corn, 26.5% flour, 30% rice bran, 5% corn, 2% shell powder, and 1% bone meal in the early stage of fattening. Salt 0.5%. In the later period of development, 35% corn, 30% flour, 25% rice bran, 6.5% sorghum, 2% shell powder, 1% bone meal, and 0.5% salt.
1, bar raise fattening. Divided into small columns with bamboo poles, each column can accommodate 2-3 ducks. The area of ​​the small bar can not be more than 2 times that of the duck body, and the height is 45 to 55 cm. It is advisable that the duck can stand. Set up drinking fountains and feeders outside the bar to allow the ducks to extend their heads to feed on drinking water. Feed supply should be adequate, feed 3 times during the day and 1 time at night.
2, feeding fattening. Mix the feed with warm water and grow it in a strip of 1 to 5 cm. Fill it in slightly after cooling. Begin feeding 3 times a day, 3-4 each time, then gradually increase to 5-6 times a day, each time 5-8. After filling, drink enough water and take a 30-minute water bath every day for digestion.
The fattening period is generally 10 to 15 days. When the duck has a body weight of 2 to 3 kilograms, it feels fat thickening by hand touching the skin, and the feather plume of the wing feather appears to be transparent.
