The scientific ingredients for ducks and ducks feed mainly on cereals, accounting for 50% to 60%, adding 10% to 20% of cakes, 10% to 15% of fishmeal, 1% of shell powder and salt, multivitamins and additives. The amount of fish meal can be increased or decreased according to the egg production rate. Feeding 4 to 5 times a day, each duck fed a daily dose of about 125 to 150 grams, can be fed twice a day during the peripartum period. The timely production of egg ducks prematurely prematurely prone to premature egg failure, too late will affect economic efficiency. The opening time should be controlled around 150 days. At the age of 100-120 days, the feed quality should be controlled, and half of the compound feed and half of the green roughage should be eaten to support the large intestine. After 120 days of age, the amount of feed should be gradually increased. Note that the stronger the sexual desire of the tempting duck, the more eggs are laid. There must be a certain number of ducks in the duck group. The ducklings were raised and one male duck was fed for every 100 female ducks. A large herd was fed every 2000 female ducks with one male drake. The male and female ratio of the egg breeding duck population is generally 20?1?30?1. The male ducks are isolated during the production period and the moulting period to avoid harassment. Supplemental light ducks should pay attention to fill light during the laying of eggs, turn on the lights at night for 3 to 4 hours, and then turn on the lights for 1 hour before dawn, day and night light to reach 14 to 16 hours to promote duck vigor. Pay attention to calcium supplement from the ducklings 15 weeks of age should pay attention to calcium. It is advisable to make up 2.5% of the dietary calcium, and gradually increase it later. When the laying duck egg production rate is below 65%, the calcium content in the diet is 2.5%; when the laying rate is 65% to 80%, the calcium content is 3%; when the laying rate is above 80%, calcium The content must reach 3.5% or more. Pay attention to the use of paddy ducks, rice straw, wood chips, etc. as padding material. Add padding once a day to cover the duck dung. Pay attention to the thickness of the pad. In combination with the ventilation of the duck house, the duck house is kept clean and dry.
