The limited feeding method is generally applied to meat breeder chickens because the breeder breeders are characterized by rapid growth, easy precocity, and high feed consumption. Adult breeders tend to deposit fat and affect the fertilization rate and egg production rate. In order to prevent the above phenomenon, it is often used to limit feeding.
As for the restricted feeding of egg-type chickens, it is mainly the bred stage, which controls the energy and crude protein levels of the diet, grasps the feed amount according to the standard weight of the strains, and controls the light time to prevent prematureness, so that the chickens will be opened in about 160 days. Production soon reaches normal egg weight and maintains egg production lasting. During the laying period, no restriction feeding is generally performed, but the nutrient level of the diet is properly controlled during the late stage of laying.
