How to scientifically restrict feed for breeding chickens? Methods for strictly controlling body weight

There are many feed restriction methods for meat-type breeding chickens. The basic principle is to adopt different feed restriction methods at different stages according to specific circumstances to achieve the goal of controlling body weight. The most widely used feed restriction program: from 0 to 2 weeks of age, free feeding; from 3 to 6 weeks of age, daily feed restriction; from 7 to 12 weeks of age, feed restriction on Thursday and Wednesday; from 13 to 23 weeks of age, feed restriction on Friday and Tuesday or Saturday and Monday; after 24 weeks of age, daily feed restriction. It is best not to use the two-one feed restriction or every-other-day feed restriction, because they are unfavorable for weighing, feeding and work scheduling. Once a scientific feed restriction program is in place, the principles of body weight control must also be grasped.
