The emphasis of weight control is on strict early-feeding, which ensures that the chickens in the late gestation and pre-opening period can only gain sufficient weight and reach the standard open-bearing weight and enter the production. In the late gestation period, not only the body weight rapidly increases, but also the reproductive system such as the ovary and fallopian tube is developing rapidly. At 24 weeks, the ovary is nearly 100 times as important as 10 weeks. In this period, combined with light stimulation, the sexual maturity and opening of the flock is very high. Neatly, the egg production peak is high and long-lasting, and there are more eggs in the whole period. In order to achieve a smaller body weight of 4 weeks in production, the limit of feeding may not be later than 2 weeks. The increase in body weight is based on the adjustment of the amount of feed to the premise. According to the weight target to determine the amount of feed, enough feed can be taken at 23 weeks to ensure that the egg is discharged and developed at 25 weeks. In order to ensure that the flock is mature and coherent, the good flock uniformity is also necessary, and the focus should be on the work of breaking the raft, grouping, and adding materials before the 16th week. At the 16th week, the uniformity of the whole group can reach 75% to 80%. Afterwards, the homogeneity is no longer emphasized too much, and the normal development should be ensured. The weight of the rearing broiler breeders must not be too restrictive in order to meet the weight standard, and the weight of the overweight birds in the 20th week or so should remain overweight at the time of opening. The correct growth pattern is more important than the correct opening weight. Otherwise, sexual maturity will be hindered and production will be postponed.
