The control of duck body weight and uniformity is closely related to the peak of egg production in ducks, the duration of peak maintenance, and the total egg production during the entire laying cycle. Should be done from the following aspects of regulation. 1. Adequate feeding position. The feed must be evenly distributed into the trough so that each duck can obtain equal feeding time and opportunities. If the feeding position cannot meet the needs of the duck group, it should be added in time. The feed should not be sprinkled on the playground outside the home, which will result in wastage of feed and be easily contaminated by duck dung. This is not conducive to the health of ducks. 2. Breeding density is reasonable. Breeding ducklings per square metre breeds 5 to 6 egg breeders and 2 to 3 meat breeder ducks. The area of ​​a general playground is 1 times the area of ​​a duck farm. The ducks of meat breeds are kept at 300-400 per group, and ducklings of egg breeders are suitable for 700-800 per group. 3. Adhere to regular weighing. Weighing should be fixed, timed, and fixed. Ducklings are said to have a primary weight when they enter the brooding house, and the weighing ratio should not be lower than 10%. The bred duck group must insist on weighing regularly, and determine the daily feeding amount accordingly, and the weighing proportion should be no less than 5%. After weighing, the average weight and evenness of the ducks in each lap, each building, and the whole group of ducks were accurately calculated. According to the weighing result, the daily feed amount for next week is determined. 4. According to weight group. Ducks with different body weights are divided into large, medium, and small groups in a timely manner. The diseased, weak, and ducklings were reared in isolation and placed in a cage with a slightly higher temperature and better light, so as to facilitate the intake of drinking water and promote rapid growth; at the same time, the feeding density was reduced, and vitamins and minerals were added to the diet. Substances, supplemented with antibiotics to prevent disease. In groups with good uniformity and body weight, individual differences were not significant and should not be reared in groups to avoid stress responses in the population.
