First, pay attention to ingredients. Ducks and ducks feed on cereals, accounting for 50% to 60%, properly 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 rate of egg production, feeding 4 to 5 times a day. Each duck fed a daily dose of about 125 grams to 150 grams, can be fed twice a day during the peripartum period. Second, pay attention to timely production. Eggs and ducks are prone to premature aging prematurely, and too late will affect economic efficiency. The opening time should be controlled around 150 days. At the age of 100 days to 120 days, the feed quality should be controlled, let it eat half of the compound feed, half of the green roughage, to support the large intestine, and gradually increase the quantity after 120 days of age. Third, pay attention to incentives. The stronger the libido of the 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 proportion of ducklings for eggs is 20:1 to 30:1. During the confinement period of the ducks, during the moulting period, the male ducks are isolated to avoid harassment. Fourth, pay attention to lighting. During the production of eggs, attention should be paid to fill light, turn on the lights at night for 3 hours to 4 hours, and then turn on the lights for 1 hour before dawn. The day and night light should reach 14 hours to 16 hours to promote the vigor of the duck glands. Fifth, pay attention to calcium. Attention should be paid to calcium supplementation when laying ducks are 15 weeks old. 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 should be 2.5%; when the laying rate is 65% to 80%, the calcium content is 3%, and the egg production is above 80%. When the calcium content reaches 3.5%. Pay attention to litter. The duck ground should use paddy rice husks, rice straw, and wood chips as litter. Each day, padding should be done to cover the duck manure. Pay attention to the pad thickness at the laying site. Combine the ventilated ventilation of the duck house and the cooling of the house to keep the duck house clean and dry.
