There are many types of wild ducks. At present, the main domesticated domestic ducks are American mallard ducks. The mallard duck is tender, delicious, and has less fat. It is a traditional nourishing food and game dish. This wild duck grows fast. The average weight of 70-day-old ducks can reach 1.2 kg. The egg production starts at about 5 months, and about 150 eggs are produced each year. The breeding methods are as follows: 1. To create a suitable wild environment: The construction of wild duck farms must meet the wild habits of wild ducks. Half of them should be used as a lounge and half as an open-air event. The activity site should be a pond or artificial pool. Some trees and grasses can be planted on the activity field, and some algae can be cultivated in the pond to create a suitable wild environment. If the breeding method is combined, the breeding site must be selected where the rivers, lakes, and other water areas are open and luxuriant. At the same time, fences and skynets should be built. Skynet is 2 meters high from the water surface, and it is surrounded by a fence to the bottom of the water. It is connected to Skynet to prevent it from fleeing. Skynet and fence holes are 3 cm and 3 cm. Nylon nets or rope nets can be used. Generally, the feeding area per 100 ducks is about 60 square meters. Second, to meet the needs of wild food: When young ducks start eating, they must add a small amount of fish meal in the feed, after a few days can be fed compound feed, while adding appropriate amount of green feed and small fish, fresh meat, oysters and other fresh animals. After feeding for one month, the protein content in the feed should be reduced to 10%, and the proportion of fishmeal and beancake should be appropriately reduced, and the roughage should be gradually increased, with the proportion reaching 20%. At the same time, every day feed 100 grams of green leaves such as cabbage leaves, alfalfa and grass to promote growth of the wild duck skeleton and postpone development. After two months, roughage must be reduced and the protein feed raised to 18%. And continue to increase green feed. Third, to strengthen the management of domestication: 1. Carefully feeding ducklings. 1 to 30 days old ducklings should be strictly controlled temperature, 1 to 3 days old 27 to 29 °C; 4 to 6 days old 25 to 26 °C; 7 to 10 days old 24 to 25 °C; 11 days later 17 to 19 °C. At the same time, soft rice straw should be laid on the ground, and the fence should be fed. Ducklings have heap habits and need to be on duty day and night to prevent death and suffocation. When you start eating, you must drink water first to ensure adequate drinking water. Drink 5 to 7 times a day. 2. Domestication management into ducks. From 31 to 70 days of age, the breeding density is 10 to 15 per square meter, and after 50 days, it begins to fly, and strict anti-escape is required. To arrange water basins, provide activity venues and wild inhabitants. 60 to 70 days of age, to prevent noisy ducks. Wild ducks are attacked by wild animals due to increased body fat and physiological changes. At this time, the performance of the duck group is turbulent, sharp decline in food intake, weight loss, and restrictions on feeding, increasing the proportion of roughage, the breeder should wear plain clothes, avoid wearing fresh flowers. At the same time, it is necessary to prevent outsiders from entering the duck house to disturb the flock. After half a month of domestication, it will turn into normal.
