Problems solved by technology

[0002] The media duck is a kind of duck between wild ducks and domestic ducks. It is domesticated by wild ducks after long-term breeding. The breeding places are mainly in Anqing and the surrounding areas of Anqing City. It is the most characteristic local waterfowl genetics in Anhui Province. As one of the resources, the breeding of media ducks is mainly based on stocking in ponds. Generally, there are few artificial feeds. Although there are many types of natural feeds, they have no significant effect on improving the egg production performance of media ducks. The existing media duck breeding industry is widespread. Poor egg production performance and low hatchability
