Generally, breeder hens are raised until they are 8 weeks old to 16 weeks old and enter the young stage, and they should start feeding with restricted feeding. The purpose is to control the weight gain of the breeder hens and prevent the breeder hens from premature sexual maturity. The breeding hens are maintained at a weight standard suitable for vigorous and high-yield, so that the breeding hens always maintain vigorous and high-yield after the start of production, so as to achieve the purpose of improving feeding efficiency.
Restrictions on feed intake.
That is to limit the feed intake of the breeding hens so that the daily feed intake of the breeding hens is limited to 80% to 90% of the free feed intake.
Restrictions on the quality of rations.
That is, increase the feeding amount of cellulose and green juicy feed, and reduce the feeding amount of concentrated feed such as corn, sorghum, and bean cake.
Restrictions on feeding time.
That is to limit the feeding time of the breeder hens, the feeding time can be restricted by daily feeding, or the feeding time can be restricted by one day a week.
Note: Regardless of which way of restricting feeding is adopted, normal water supply should be ensured. The drinking water of breeder hens cannot be restricted, so as not to affect the high-yield performance of breeder hens and reduce breeding efficiency.
