The energy level of the feed used for filling ducks is 11.5-12.5 megajoules / kg of metabolic energy and 14-15% of crude protein. The following table shows the feed reference formula for Beijing stuffed duck.

The amount of filling should be gradually increased according to the age and growth of the meat duck, and do not increase suddenly to prevent the meat duck from dying or paralysis caused by indigestion.
