First, the duckling period of feeding and management ducklings refers to the ducklings from the shell to 20 days of age. The ducklings average about 42 grams in shell weight. They are afraid of cold and are afraid of heat. The temperature should be controlled at 25-32°C. Ducklings have a habit of agglomeration. As the accumulation time increases, mid-ground ducklings can die. In order to avoid this kind of loss, a small group of night-time cages are used to store accommodation, with about 20 cages per cage. Ducklings have a small stomach and stomach capacity. To meet the nutritional needs of fast growth and development, full-price ducklings should be used for feeding. Small amount of ground feeding should be used. Each day and night can be fed 5 to 6 times. Drinking water should be guaranteed at each feeding. There is plenty of clean water. Ducklings should be given an appropriate amount of drinking water within 24 hours after hatching, and then eat it to facilitate the elimination of dirt accumulated in the digestive tract during the embryonic period. After 3 to 4 days, it should be properly placed in shallow water to allow it to fully move to promote digestion and metabolism, and to keep the ducklings clean. However, due to the underdevelopment of the duck's tail glands, the moisture resistance of the feathers is poor. Generally, the time for the initial release of the water should not be too long. It must be flexibly controlled according to the local climate conditions. In addition, we must pay attention to changes in the water temperature, and we cannot drink water at noon during the summer season. We cannot drink water in the cold season sooner or later. At the age of 7 to 8 days, grazing can be carried out according to local conditions. Beaches, fields, ponds, ditches, river banks, etc. are good places for ducklings. Grazing time should be mastered during the initial grazing, and it is most appropriate to grazing until most ducklings come ashore. At the same time, as the young duckling grows, the grazing time is appropriately extended, and the conditional reflection of the sound of the duck is slowly trained so that the duck group can consciously concentrate on hearing the call and facilitate grazing management. Although ducks like to live in the water, but the duck houses and rest areas are required to be clean and dry, so that it is cool in winter and cool in summer, and grass should be added in cold seasons. Feeding utensils should be kept clean. Ducks should be immunized against liver disease at 1 day of age.
Second, the rearing period of rearing and management during the rearing period refers to 20 to 40 days old ducks. The young ducklings in the breeding period are active and lively, and can gradually extend the grazing time with the increase of the age. It is the best time for training grazing. The feeding of feedstuffs can be controlled flexibly according to the feeding conditions, and the full-price pellets should be properly added to the ducks. With the increase of the age, the individual ducks gradually increase, the feed consumption also increases, and the coarseness resistance increases. In order to reduce the cost of feed, protein feeds can be gradually reduced, and appropriate amount of general feeds can be added. After the grazing, the rest area of ​​the duck requires quietness. At the same time, attention should be paid to the growth and development of ducks. For some slow-growing ducks, they should be divided separately to strengthen feeding and management in order to increase the growth and development of ducks, ensure that the ducks grow in unison, and lay a solid foundation for the consistent production of ducks. . Ducks at this stage can be immunized against duck plague approximately 30 days of age based on the growth and development of ducks and the health status of ducks.
Third, the young ducks feeding and management Young ducks from 41 days old before the opening, also known as the reserve duck. The ducks in this stage are well-fed and the ducks are strong in physique, agile in movement, strong in feeding power, resistant to rough feeding, and have strong adaptability to climate and fast growth and development. Feeding and management should be based on local conditions, make full use of outdoor grazing to reduce feed supplements, thereby reducing feed costs. When grazing in ducks is not enough, the full-price feed should be properly added to ensure the nutritional needs of growth and development. This will lay a good foundation for laying eggs and allow the ducks to lay eggs as soon as possible. One bird outbreak prevention injection was performed at 60 days of age. At this stage, attention should be paid to adjusting the status of the duck population. It should not be too fat or too thin, so as to facilitate the high yield and stable yield of the duck population after the start of production.
IV. Feeding and Management of Adult Ducks Ducks with egg production capacity are called adult ducks. In terms of feeding, it is necessary to ensure adequate feed supply, especially protein feed, to maintain long-term stability and must not be easily replaced. If it needs to be replaced, attention must be paid to the climate, duck fat, leanness, and egg production, and gradually replace them. If there is a noticeable drop in egg production or other abnormality during the replacement, management measures must be strengthened or the replacement must be stopped. There must be long-term plans and arrangements for grazing in order to ensure the stability of pastoral areas. Otherwise, the shift of pastoral areas during laying will also reduce the egg production rate, especially during the laying of eggs in the light pastoral areas. When non-transfer is not possible, a gradual transition should be taken, and at the same time, nutritional supplements to the egg-laying ducks should be strengthened and management must be strictly implemented, otherwise serious production suspension will occur. In the feeding and management process of adult ducks, care must be taken. Ground feeding: regular, qualitative, quantitative, Japanese food to eat less full, not too hungry, dinner must be fully fed, so that the ducks squatting overnight to meet their nutritional needs. Diligent rush: It is an effective way to strengthen the management of pastoral ducks. This will not only make full use of pastures, but also promote the metabolism of pastoral ducks, increase appetite, and make female ducks diligent in foraging; it should be noted that fasting fast, full belly slow In time, it was strictly prevented that the ducks were seriously disturbed due to the riots, which was not good for laying eggs. Diligent care: Appropriate arrangements for feeding and resting time for ducks, paying attention to changes in the climate, keeping cool in winter and cool in summer, increasing night feeding properly as required, and preventing animal beasts from disturbing; replacing bedding regularly to keep the inside and outside environment clean Dryness and ventilation prevent the occurrence of diseases. These are effective measures to promote the high yield and stable production of Jinding duck.
Jinding duck efficient feeding technology
Jinding duck is one of China's excellent duck breeds. Currently, it has been raised in many areas in China. According to the physiological characteristics and living habits of Jinding duck, it can be divided into the following four stages in feeding and management:
