1. Shelter: When breeding, you can build a duck house in the north facing south at the leeward sunny place, and use a net to surround the duck house, playground, and leisure water, so as to form a “three-in-one†eco-environment of sherbet-she-water. system.
Second, ducklings feeding and management: From the shell to the 45-day-old duck called ducklings. Freshly hatched young ducklings are not sound enough to digest, have relatively small feed intake, and have poor ability to transform and utilize feeds and to digest and absorb nutrients. The quality of feeding and management at this stage directly affects the future growth, development, production, egg production, egg weight and other production performance. After the ducklings are hatched, due to physical strength and water consumption, they need to enter drinking water and timely release water and food. Within 24 to 36 hours of shelling, in addition to feeding 0.5 ml (about 3-4 drops) of 0.01% oxytetracycline water, it is advisable to allow it to drink water in a timely manner. The amount of drinking water is not limited, the number of drinking water and the phase of feeding adapt. At the same time, according to the ducklings physique strength, the size of group feeding, and do a good job of insulation. Ducklings should be discharged for the first time (sewer) with 5 days of age. Place 20-30 cm deep water in a large tub or plastic basin and place the ducklings in the basin for about 2-3 minutes to stimulate their nerves. Then take them out and put them on the mat to eat. After 7 days of age, a shallow ditch can be dug in the sports ground. The depth of water is about 10 centimeters. Spread the material next to it so that the ducklings can freely go into the water, drink water, and feed for 5-10 minutes each time. As the age increases, water can be released in shallow ponds, ditches, and rice fields. The time for releasing the water should be gradually lengthened, but it is better to use ducklings with feathers ashore. The frequency of water discharge is generally twice a day. It is advisable to use 9:00 am and 3:00 pm. Free water can be released after 30 days of age. Appropriate temperature during brooding: 1-3 days of age is 25-26°C at 27-29°C; about 23°C at 8-14 days of age. The temperature in the house should be stable, avoid sudden fluctuations, uneven hot and cold, so as not to cause piled ducks to cause crushed death, crushing, affecting the survival rate and resistance to disease, so that the youngsters struggle to block upstream growth and development. The breeding density for brooding is 12-15 per square meter, and the relative humidity in the house is 75%-80%. Ducklings should generally be eaten within 24 hours of shelling (first feeding). When feeding, ducklings are fed by size, strength and weakness. When it is fed, steam the cooked rice into rice grains, spread it evenly on the mat, add it while eating, and feed it until it becomes full. 5 days of steamed small rice and 1/3 of the tender leaves, water grass, ovum, etc., and add 0.02% of a variety of vitamins. 6-10 days old rice mixed with 1/4 of the mixed feed (corn 60.7%, soybean cake 25%, wheat bran 6%, fish meal 5%, yeast 1.5%, bone meal 1%, stone powder 0.5%, salt 0.2%, Trace elements 0.1%), and with a suitable amount of "live food", such as soaked in water and chopped scorpion, aphids, small fish or snail meat and so on. After 10 days of feeding, 5 times a day, you can feed bloated millet, mixed with 1/3 of the mixed feed. In the process of brooding, it is an important part of raising the survival rate of young ducklings to do a good job of preventing and controlling diseases. For this reason, the ducklings' sheds should be ventilated and dry, the bedding should be kept clean, the duck dung and the grass bedding must be removed, and the feeding trough and drinking fountain should be cleaned every day. Disinfect with 20% lime water or 2% caustic soda every 10 days to prevent the ducklings from getting sick.
Third, the feeding and management of ducks: 46 days before the egg is called duck. The ducks in this stage grow fast, consume more material, and require rich nutrition to meet the growth and development needs of this stage. Can be fed 3 times a day, the amount of vehicles should be even, not hungry and impermanent. Pay attention to strong and weak groups to promote the balanced growth of ducks. The fine, green and coarse materials should be properly matched so that the ducks can eat well. In management, the area of ​​the playing field should be enlarged. Feed as much as possible outdoors to keep the feed fresh and the drinking water clean. At the same time, the pad should be changed frequently. Material to prevent moisture. In the hot summer season, the ducks should be fully bathed and cooled, and a sun-shading pergola should be set up on the playground to prevent heat. Circles should be kept clean, dry and ventilated. Breeding ducks should be bred in time to eliminate the sick and weary ducks, and they must be fed in limited quantities to prevent individuals from becoming too large and premature. Premature egg production, small egg production, short egg production duration, and premature aging are all phenomena.
Fourth, breeding and management of breeding ducks: ducks need to maintain life activities and production of eggs, so both feed and feed well, to feed the full price feed. Its diet is (%): rice flour 14, fish meal 5, bean cake 21, broken rice 57.3, shell powder 2.5, salt 0.2, plus a variety of vitamins 0.01% and the amount of trace elements. When selecting materials, local feed resources should be used as much as possible to provide a variety of animal protein feeds to ensure the balance of amino acids. If supplemented with 1% gypsum, it can accelerate the moult of ducks and increase the rate of laying. Daily, quantitative feeding 3 times a day, but also regular water. At the peak of the egg production, feed it once at night. Each duck feeds 0.125 kg of concentrate and 0.1 kg of green feed each day. When you feed, you can feed it now and do not feed it with moldy feed. Releasing water in the morning, afternoon and evening each time is generally half an hour, and the time can be extended in summer. Before the arrival of the winter, it is necessary to do a good job in cold preservation and warming work. In the cold season, early return should be late. A 25-watt electric lamp can be installed in every 60 square meters for additional lighting. Summer homes should be often sprinkled to cool off. In the usual feeding and management process, it is necessary to keep the house and litter clean and dry, remove the excrement and dirt in time, and disinfect the equipment once a week, and set a disinfection tank at the entrance and exit of the house. Normal ducks can be fed with 0.5% sulfadiazine or sulphadixime for 3-5 days to prevent fowl cholera, and at the same time inoculated with duck gizzard and other vaccines. In the event of a duck disease, treatment should be promptly isolated to prevent spread. To minimize and avoid sudden changes in the environment, startle, etc., keep the environment quiet, so as not to cause the duck's stress response.
Duck feeding technology
The wild duck, also known as the pheasant, is known as the "Oyster" in the earliest ancient Chinese book "Er Ya" and belongs to the family of birds and ducks. The mallard in the narrow sense only refers to Mallards. In the broad sense, it includes a variety of birds of the family Anatidae. Commonly, there are mallards, ducks, ducks, ducks, and ducks. They are usually smaller than ducks, and have toads between their toes. And flying, many groups of quacking rivers, rivers, lakes, omnivorous or staple food plants. Its duck meat is eaten in total, and feathers can be made into high-grade duck downs. It is an important economic waterfowl. Wild ducks have been domesticated and cultivated from generation to generation, basically losing their instincts such as flying, nesting, hatching, and brooding; and the performance of meat production and egg production has been significantly improved, with tender meat and delicious soup flavor.
