Feeding fattening ducks can grow to 1-1.2 kilograms 50-60 days after feeding, at this time feeding high-energy, low-protein compound feeds to limit exercise. The feed formulation was: corn 36%, soybean cake 10%, wheat 20%, rice bran 18%, silkworm cocoon 2%, wheat bran 10%, shell powder 4%, plus 500 mg auxin, 100 g olaquindox. The compound feed was adjusted to a dry paste with water, and it was hand-rolled into a round bar with a diameter of 3-6 cm and a length of 5 cm. The operator sits on a stool with his legs pressed against the lower part of the duck body. The right hand sticks the water to make it lubricate, and then fills it from the mouth to the esophagus. Fill 3 times a day. On the 1st to the 3rd day of the fattening, 3-4 round sticks were filled every time, and 4-6 roots were filled every 4-8 days. Each time after 8 days, 6-8 roots were filled. After filling, you can drink enough water for a few minutes, and the fattening period is usually 10-15 days. When the duck weighs more than 2 kilograms, the subcutaneous fat is thickened by hand, and the wing feather is transparent when it is put on the market. China Agricultural Network Editor
