Meat duck rearing fast fattening technology
First, the choice of species. Suitable duck species include Cherry Valley Duck, Beijing Duck, Kangbei Duck, Jianchang Duck and Shanghai White Duck. These breeds are tame, hi gregarious, strong in cold resistance, fast in growth and development, good in fattening performance, high in slaughter rate, tender and delicious, and very suitable for feeding. Second, young chicks. Ducklings are called young chicks from the hatched to 20-25 days old. The purpose of nurturing young chicks is to strive to improve the survival rate of more than 90% to facilitate the development of large-scale robust ducklings, lay a good foundation for the young. 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, the eyes are divine, and the body is well-balanced and healthy. 2, insulation. After 7 days of hatching, the ducklings should be maintained 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, dry straw can be cut in the basket to make a flat bottom. Keep 10 to 20 broods in each quail, cover the old clothes, and cover them with fluff (note the air permeability), so that the ducklings can be kept warm by each other. 3, open food. Drink water before eating, water temperature around 20 °C. Drinking water for the first time should add 0.04% potassium permanganate to the water and feed it once every 1.5-2 hours. Only feed 80% full at a time. Use boiled rice and soak in clean water to remove stickiness. After the drain, mix in 1.5-2% white sugar, let the ducklings eat, eat and sprinkle 2 times a day. 4, drinking water and feeding. From the 2nd to the 4th day after the start of food, drinking water and feeding 5-6 times a day, 4-5 times for 5-15 days, and 3-4 times after 15 days. Implement drinking water first or drinking while feeding. From the fourth day onwards, no sugar was added and compound feeds were added. The quantity was from little to large, and the compound feed was fully fed on the 10th day. The feed formulation was as follows: corn, 48%, broken rice, fried bean, fried pea, 10%, fish meal, 6%, wheat, rice bran, 5%, cocoon, 4%, bone meal, gypsum, 1%. For ducklings to be fed with appropriate amount of green and green feed, green feed can account for about 20% of the diet for 4 to 10 days, and 30 to 40% after 10 days. Single feed, mixed feed can be. 5, put water. 2-5 days after hatching, ducklings can be placed in water for 5-7 minutes. The wet feet then sink first, allow them to swim, play, drill, wash, and then regularly drain water every day. Before 7 days, water was released 2-3 times a day for 10-20 minutes. After 7 days, the ducks were placed in a shallow pool of 8-10 cm deep; after 15 days, the water depth in the pool was increased to 15-20 cm. Third, feeding ducks. Ducks are called ducks in this stage of 20-50 days or 25-65 days. The requirements for its cultivation are to ensure its nutrient supply and give full play to its advantages of rapid growth and development during this period. Feeding is mainly based on feeding, supplemented by grazing, feeding in groups, and the principle of reducing fines and thickening. 1, house feeding. Suitable for large varieties of white feathers such as Cherry Valley Duck and Beijing Duck. The venue is available next to Tangku or Riverside, but also in the courtyard. The pens should be air circulated. Houses should be made of bamboo strips with a height of 60 centimeters and 5 square meters of ducklings. The ducks can be raised from 20 to 30, with 70 to 100 birds each, separated by a fence. In the side of the sidewalk, hanging troughs and troughs require an average of 5-10 cm for each duck. Ducks account for 35-40% of bran and 40-45% of cereals. Its formula is: corn 62%, wheat bran 15%, fried pea 6%, fishmeal, 7% of the cake, bone meal 2.8% , Salt 0.2%. Feed 4 times a day, feeding water while feeding. At the same time to add green material, the general mix of green material and compound feed is 1-1.5:1. In addition, we must strengthen the grazing of the middle-duck bath in the house-fed, and grazing once every day before 11 o'clock in the morning and after 4 o'clock in the afternoon. Each time grazing no more than 1 hour, after the grazing, wait until it is dry feathers and then enter the bar. 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. Grazing time is generally 1 time in the afternoon, before 11 o'clock in the morning and after 4 o'clock in the afternoon. At the same time, feed supplements 2-3 times a day. Its feed formula is: corn 35%, wheat 16%, wheat bran 23%, fried hudou 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 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 when they grow fastest, they must Strengthen fattening. Use high-energy, low-protein compound feed during fattening. The reference formula is: 35% corn, 26.5% flour, 30% rice bran, 30% rice bran, 5% of shellfish (fried), 2% of shell powder, 1% of bone meal, and 0.5% salt in the early stage of fattening; 35% of corn in the late fattening stage. 30%, rice bran 25%, sorghum 6.5%, shell powder 2%, bone meal 1%, salt 0.5%. 1, self-fertility fattening. The mixed feed should be placed in water and wet for 3-4 hours until it is fermented and then fed. 4 times a day and 1 additional feeding at night, feeding water while feeding, and feeding the duck into the bath after feeding. The duck house should be dark and the duck farm should be clean and well ventilated. 2, bar 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 45-55 cm. It is advisable that the duck can stand. A drinking fountain and a feeding trough are set outside the bar to allow the duck to extend its head to feed on the water. Feed supply should be adequate, feed 3 times during the day and 1 time at night. 3, feeding fattening. Mix the feed with warm water and grow it in a strip of 1-5 cm. Fill it in slightly after cooling. Begin feeding 3 times a day, 3-4 times each time, then gradually increase to 5-6 times, 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 10-15 days. When the duck has a body weight of 2-3 kilograms, it senses fat thickening by hand touching the skin, and the feather plume of the wing feather appears transparent. Fifth, strengthen prevention. In addition to beefing up the feeding and management of meat ducks, the prevention and epidemic prevention must be particularly well done. Ducks and duck farms must be completely sterilized with bacteria before the ducks are released or by drugs such as Suhl. Diligently sweep the duck houses, diligently remove residual dung residue, and maintain good ventilation. 20 ml of ducklings were given 1 ml of attenuated vaccine to ducks and 20 ml of ducklings were given 2 ml of cholera vaccine every 30-40 days. Normally available sulfamethazine or sulfathiazole feed 0.5 to 1% of the proportion of feed fed for 3 to 5 days, stopped after 10 days and then fed; 0.01-0.02% potassium permanganate drinking water can also be used to prevent epidemic, the effect is very good.
