What are the principles of restricted feeding for meat-type breeding chickens?

Restricted feeding should be carried out during the production stage. Starting from 2 weeks after the peak of egg production, the amount fed should be determined based on body weight. By adjusting the feed amount, the body weight of the breeding chickens is controlled within a relatively suitable range. The degree of feed restriction mainly depends on changes in body weight. Generally, meat-type breeding hens are required to reach a body weight close to 2 kg by 20 weeks of age. During restricted feeding, the weekly weighing results are compared with the standard to determine the actual weekly feed amount.
