Methods of restricted feeding of breeder ducks

Restricted feeding of breeder ducks can prevent precocity. During the period from 0 to 28 days of age, ducklings are generally not limited to feeding; from 5 to 18 weeks of age, limited feeding should be carried out, that is, according to the feeding standards of meat breeder ducks and the growth and development of breeder ducks, the feeding amount of breeder ducks is determined, and the protein content in the feed is gradually reduced from 20% to about 16%. After 18 weeks of age to the beginning of production (about 26 weeks), the feed should be replenished in time, the protein in the feed should be increased, and the feeding amount should be increased day by day.
