Long-term consumption can strengthen the body, cure diseases and prolong life. It is the first choice food for dietary supplements regardless of spring, summer, autumn and winter. It is precisely because of the excellent quality of Liancheng White Duck that combines dietary and pharmacological functions that it is in line with the consumer needs of modern people. In the 1970s, it was included in the "Chronicle of Chinese Poultry Breeds". In 2000, the Ministry of Agriculture Announcement No. 130, Liancheng White Duck It is included in the national livestock and poultry breed resource protection list and is known as the only medicinal duck in the country. There is a local nursery rhyme in Liancheng: Black girl, swimming in the water; the only medicinal use is the best; the emperor will not worry after eating it.
What are the key points of Liancheng white duck breeding technology?
The duck duck is known as the only medicinal duck in my country. It has the effects of clearing heat and detoxifying, nourishing yang and reducing fire, eliminating phlegm and resuscitating the mind, calming the mind and calming the mind, appetizing and strengthening the spleen. The duck is not greasy and has a unique soup taste. The meat is delicious and fragrant. Because it has special pharmacological effects and special flavor that other poultry do not have, as people's awareness of health care increases, the white duck, a rare bird, is increasingly valued by health experts and farmers. It has become a good dietary supplement for people. Now the white duck breeding technology is introduced as follows:
1. The method of boiling water for cooking is: spread a piece of plastic sheet, use wooden sticks to pad it around, and lower one side appropriately to facilitate the release of water. Then pour clean water into the water, so that the deepest part of the water does not exceed the duckling's knee joints. In winter, you can add warm water and put some rice or green duckweed in the water. Then put the ducklings into the water, preferably 30 ducks per square meter, and change the water every time to promote the discharge of meconium. Start eating while boiling the water, usually with uncooked rice. After 3 days of age, add full-price compound feed, and after 10 days of age, complete feed can be fed.
2. Moisturizing and Insulating White ducks love water, but are most afraid of high humidity. If the humidity is too high, it will easily cause difficulty in breathing. In addition, appropriate humidity will bring a good environment for the reproduction of pathogenic microorganisms, and ducklings are extremely susceptible to diseases. It is appropriate to keep the relative humidity below 65%. Temperature is a key factor affecting brooding rate. The starting temperature of the brooding room is generally 30°C, and then decreases day by day. After 20 days of age, it usually reaches room temperature. The key to heat preservation is to "watch the ducks and apply warmth". If the temperature is too low, the ducks may cry, or they may squeeze under the heat source, causing them to be crushed to death. Freeze to death; if it is too hot, stay away from the heat source and breathe through your mouth. In severe cases, it may also cause some casualties. If the ducklings move freely in small groups indoors. Lying quietly after eating means that the temperature at this time is at its best.
3. It is advisable for ducklings to feed ducklings under 1 week of age ad libitum. Make sure there is feed in the trough, but it should be noted that there should not be too much leftover feed in the trough, and be sure to add it sparingly to prevent spoilage. After 1 week of age, feed 6 times a day, after 2 weeks of age, feed 4 times a day, and after 3 weeks of age, feed 3 times a day. When raising ducklings, attention should be paid to the breeding density. If the density is too high, it will affect growth and development and make them susceptible to disease; if the density is too small, it will affect economic benefits.
General brooding density: 20 to 25 chicks per square meter at 1 week old, 15 to 20 chicks per square meter at 2 weeks old, and 10 to 15 chicks at 3 weeks old.
4. After 30 days of breeding and management, the crude protein content in the feed can be appropriately reduced. After 60 days of age, feeding restrictions should be implemented. Each duck should be fed 60% of the normal amount of feed every day. Feed, or feed twice a day, and feed 65% of the total amount. First, it can reduce costs, and second, it can postpone the production period to facilitate high yield. At 90 to 100 days of age, the laying ducks should be fed full-priced egg-laying duck feed, and they should mainly feed themselves. The adult ducks should be divided into groups according to size and physical strength. Generally, there are 100 ducks in a group, and 50 ducks can be grouped if conditions permit. . At the same time, due to the increase in feed intake, the excrement also increases. The cleaning and sanitation of the duck house and sports ground should be strengthened. Daily cleaning should be carried out to remove feces in a timely manner to keep the house dry and prevent the litter from becoming wet. In addition, the mental state of the ducks should be observed every day. If it is found that there is not much food, no food, or poor energy, they should be picked out for treatment in time and raised individually.
5. Breeding duck breeding and management Breeding ducks should be raised regularly, quantitatively, and frequently, and use full-price egg-laying duck feed. Put some fine sand and gravel in the sports ground to allow the breeding ducks to find food on their own to facilitate digestion. If they are raised in captivity, feed some green feed around 10 a.m. every day to supplement vitamins, which can increase the egg fertilization rate. Breeding ducks should be exercised to prevent excessive fat from affecting egg production. The duck house should be kept hygienic and disinfected at least every half month.
6. Hygiene and epidemic prevention: duck droppings should be removed every day, clean bedding should be replaced, and the duck house and its surroundings should be fully disinfected with disinfectant at least once a week. The mental state of the ducks should be constantly observed. If any ducks eat less food or have a weak constitution, they should be managed individually. At the same time, pay attention to disease prevention. At 1 day of age, 0.5 to 1.0 ml of attenuated duck viral hepatitis vaccine can be injected subcutaneously. At 20 days of age, each duck is injected with 1.5 to 2 doses of duck plague vaccine. On 60 days, Inject fowl cholera vaccine at age 10.
