First, build wild duck farms Barren mountain forests should be far away from residential areas, duck houses built in the high ground, leeward sunny, flat land, easy to prevent pests and epidemic disease transmission in the mountains, using bamboo and adult-shaped bar, On both sides, drip water is 1.5 meters high, covered with thatched grass and surrounded by bamboo sheets to make it cool in winter and cool in summer. The size and length of the duck house are determined according to the number of ducks, and generally 8-10 ducks per square meter. At the same time, sheds are erected in barren mountain forests for ducks to shelter from wind and rain and store feed. Duty rooms and warehouses are built next to the duck houses for easy supervision and work. In addition, there should be enough activity places to plant trees and grass, and ditches, ponds and algae should be cultivated in the water. In order to prevent the wild ducks from fleeing, the entire activity site should be closed by a net. Skynet is about 2 meters above the ground and is integrated with the fence. The meshes are 3 cm and 3 cm. Second, the selection of good duck breeds practice has proved that artificial feeding ducks are currently the most suitable mallard duck, the artificial domesticated duck breeds, body size, generally raised to 80 days, weight is 1.4 kg of meat standards. The mother ducks began to lay eggs in more than five months and had an annual production of nearly 200 eggs. The taste of meat and eggs is still fresher than that of natural wild ducks in the Lake District. In particular, the meat does not have the taste of domestic ducks. It is a good tonic for all seasons, and the domestic and foreign markets are extremely popular. Third, the rational preparation of feed duck feed nutritional requirements and duck is basically the same, under normal circumstances, can feed special feed for ducks, such as self-made feed, can refer to the following formula (%): ducklings, corn 47.3, wheat 15 , wheat bran 10, cottonseed cake 22, fish meal 4, shell powder 1.5, salt 0.2; duck, corn 40.8, wheat 14.5, rice bran 17.5, rice 8, cotton cake 14, fish meal 4, bone meal 1, salt 0.2; egg Duck, corn 35 before egg production, rice bran 15, rice 36.8, cottonseed cake 10, fish meal 2, bone meal 1, salt 0.2, egg production 24, rice bran 7, rice 37, cotton cake 21, fish meal 5, bone meal 3, Shell powder 2.7, salt 0.3. Fourth, strengthen the feeding and management (A) ducklings (1-30 days old) feeding and management key to grasp the appropriate temperature, 1- to 3-day-old is 27--29 °C, 4--6 days old 25--26 °C, 7--10 days old 24-25 °C, 10 days old 17--19 °C. Generally, brooding is done on flats. The floor is covered with soft straw and separated into small columns. Each column is about 2 square meters. Each column is equipped with a heat-retaining lamp. Each column of the 7-day-old will raise 50--70 eggs. As the ducklings have a slumbering nature, they should be on duty day and night, and tapping the heap once every 1 hour to prevent piles from dying and suffocating ducklings. Adjust the density after 7 days of age. When you start eating, you need to drink water first, and then add appropriate amount of complex vitamin B to your drinking water. If you want to have enough clean water to drink, don't cut your water. The number of feedings is usually 7 times a day for 10 days, and 4 - 5 times for a day after 10 days of age. Each time you feed compound feed, you also need to properly add young materials (shredded) and kelp such as young grasses and leaves. Fine powder and small live fish, shrimp and other live animals. Note: 7- to 15-day-old ducklings can be released in shallow water channels on sunny days and water in ponds after 15 days of age for healthy growth. (2) Feeding and management of ducks (31--80 days old) In order to make ducks grow long, the whole feeding period is not limited to supplying compound feed, allowing them to freely feed and provide enough clean drinking water. After 50 days of age, ducks begin to fly due to increased body fat and physiological changes. They must be strictly prevented from fleeing. The breeder should wear plain clothes to prevent outsiders from entering the yard and disturbing the duck population. (3) Ducks (after 80 days of age) feeding and feeding 2 to 3 times a day before laying eggs, feeding them less in the morning, letting them do more activities in barren mountain woodlands, eating more natural feed, and feeding them at noon or even not feeding. Feed it before going to bed at night. During the egg production period, the ducks produce more eggs and produce “game†eggs. They should not feed their eggs every morning. The ducks should be allowed to move freely in barren hills and forests to feed on natural feeds. At noon, they can hold enough material and water in the sheds to allow them to collect freely. Eat, feed the duck back to the duck house and feed it before the sun goes down. During the entire production period, some shallow nests can be artificially made on the ground and some soft straws can be placed for egg production. Fifth, serious disease prevention and treatment of mallard ducks (especially mallards) have strong resistance to disease, but due to large groups of artificial feeding, we must seriously prevent epidemics. Prevention of duck plague use duck plague attenuated vaccine, in the ducks raised to 20 days of age when each muscle 1 ml; to prevent duck cholera available bird cholera vaccine, in ducks raised to 30-40 days of age, each intramuscular injection of 2 ml . Normally available sulfamethazine or sulfathiazole 0.5% - 1% of the proportion of feed mixed feed 3-3-5 days, stop after 10 days and then feed; can also be used one thousandth of potassium permanganate water epidemic prevention, the effect is very it is good.
