The advantages of raising ducks in cages allow for efficient use of space within duck houses, increasing stocking density and maximizing yield per unit area. This system also enables the use of mechanized equipment, which reduces labor intensity and improves overall efficiency. With a well-balanced diet, ducks consume feed more evenly, leading to faster growth and a reduced slaughter time of approximately 60 days. This results in about a 10% reduction in feed costs. Cage farming is fully controlled by humans, minimizing external stress, which helps prevent many infectious and parasitic diseases. However, this method requires higher standards in feeding and management.
Duck sheds and cages are typically arranged in two or one row in the north-south direction, with space left on both sides or in the center. Each cage measures 2 meters in length and 1.2 meters in width, constructed using bamboo or wire mesh. The floor mesh size is 1.5 square centimeters. A fence 0.5 meters high is installed around the cage, made from wooden strips that are 2.5 cm wide and 2 cm thick. The spacing between the strips is 3–4 cm, allowing ducks easy access to food and water. Troughs or automatic drinkers should be placed in front of the fence. Cages can be stacked 2–4 layers high, with the upper layer positioned 1.2 meters above the ground and the lower layer at 0.6 meters. Feces collection baskets are placed beneath the cages, extending 20 cm below the top of the cage for easy cleaning.
Feeding and management during meat duck production involves specific feed formulas. For ducklings (days 1–25), the feed should contain 20% crude protein, 3.9% crude fiber, 1.1% calcium, and 0.1% phosphorus. A reference formula includes 50% corn, 20% cake, 10% broken rice, 10% bran, 7.5% fish meal, 1% meat powder, 1% shell powder, and 0.5% salt. For medium ducks (days 26–45), the feed should have 17.5% crude protein, 4.1% crude fiber, and 0.5% calcium and phosphorus. The reference formula includes 50% corn, 12% bran, 10% broken rice, 0.5% salt, 5% vegetable cake, 17% wheat, 4.5% fish meal, and 1% shell powder. During the fattening period, the initial formula includes 35% corn, 26.5% flour, 30% rice bran, 5% fried beans, 2% shell powder, 1% bone meal, and 0.5% salt. Later, the formula changes to 35% corn, 30% flour, 25% rice bran, 6.5% sorghum, 2% shell powder, 1% bone meal, and 0.5% salt.
Disease prevention measures include providing ducklings with drinking water containing 0.02% potassium permanganate solution on days 1–5 and 9–13, and 0.02% furazolidone on days 6–8 and 14–16. Excrement should be swept daily, and feces removed once a day, which can be used as fish feed or pig feed. The duck house should be disinfected with lime water every seven days. Common diseases such as gizzard worm, fowl cholera, and viral hepatitis require regular vaccinations. Ducklings receive a live attenuated hepatitis vaccine at one day old, and an attenuated duck plague vaccine at 20 days old. Preventative medications like 0.1% oxytetracycline can be added to feed every five to seven days for three days. Ducks should be closely observed, and any sick birds treated promptly.
