From the beginning of the production of the first egg to the highest peak of egg production, the egg production period is also called the initial period. The main means of feeding and management at this stage is feeding. In the late winter and early spring, we must make full use of natural pastures so that the ducks will get good hair and good food. The amount of supplement is generally 80% full. Of course, you must hurry to eat more, but you can't feed your whole meal to encourage the duck to eat wild food. Supplementary feeds can be the worst quality in a year, such as glutinous rice, sprouts, floating wheat, floating beans, sorghum, etc., because ducks at this time can make full use of these inferior feeds. Insufficient natural light in early spring, in order to stimulate the development of duck gonadal, artificial lighting can be added. In order to make full use of natural lighting, early and late delivery methods should be adopted.
In a grazing area where the wild feed condition is better, after feeding one meal, the new feathers of the duck grow rapidly, the body lice increase, and the yolk increases. Some ducks are more active in action and often go out to hurry to feed. Food time is longer. If the feed in the grazing area is not very rich, the ducks sometimes make loud calls and it is necessary to add meals.
