How to regulate duck body weight and evenness

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. First, the feeding method requirements. 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, the feeding position should be supplemented. Sprinkle the feed on the playground outside the home and the feed is wasted. Moreover, feed is often contaminated by duck droppings and is not conducive to the health of ducks. Second, control the breeding density. In order to ensure a reasonable increase in duck body weight and a high uniformity in duck populations, the breeding density and population size of the duck population should be strictly controlled. Ducklings per square meter were reared for 5 to 6 ducks, and 2 to 3 meat ducks were reared. The area of ​​a general playground is 1 times the area of ​​a duck farm. The number of meat ducks per group is maintained at 300-400, and 700-800 ducks per duckling are appropriate. Third, adhere to regular weighing. Weighing should be fixed, timed, and fixed. The ducklings enter the brooding house and they must weigh their first birth. The weighing ratio should not be less than 10%. The bred duck group must adhere to the principle of weighing regularly and determining the daily feeding amount according to the growth and development of body weight. The proportion of individuals weighed should not be less than 5%. After weighing, the average weight and weight uniformity of each lap, each building, and the entire group were accurately calculated. Calculating the weight uniformity is calculated using the standard body weight and the actual average body weight of 5% in order to make a correct assessment of the weight and evenness of the duck population. Based on the weighing results, the daily feed amount for the next week was determined. Fourth, according to weight grouping. According to the weight and uniformity of ducks, ducks with different body weights were adjusted to the corresponding groups in large, medium and small. Through eye and hand touch, the diseased, weak and ducklings were raised in isolation and given special care. They were placed in a cage with a slightly higher temperature and better light to facilitate the intake of drinking water and promote its rapid growth. Reduce their stocking density, dietary supplements of vitamins and minerals, and can be 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.
