A few weeks before the opening of the pen is the transition stage from the growing period to the laying period of hens. At this stage, not only a series of work, such as cage rotation, selection and elimination, immunization, feed replacement, luster enhancement, etc., have caused great pressure on chickens, but also during this period, the physiological changes of hens are drastic, sensitive, weak in adaptability and poor in disease resistance. If the feeding management is improper, it will easily affect its egg laying performance. Adding Haitaibao to feed can improve the immunity and egg production of laying hens.

First, the egg production rate will increase. If the egg laying rate is 50%-80%, the egg laying rate will be improved after using Haitebao. If it is above 90%, it can stabilize the egg laying rate and effectively extend the egg laying time.

Second, the weight of eggs has increased. The size of eggs in the experimental group and the control group may be similar, even smaller, but when weighing and comparing, those who eat Haitaibao are generally heavier.

Third, the thickness and hardness of eggshells are improved, and they are not easy to be damaged.

Fourth, the egg white is thick and the yolk is bright.

Fifth, the feces are tasteless, which can effectively improve the breeding environment.

Sixth, it can effectively improve the utilization rate and disease resistance of feed.

Seventh, it can effectively prolong the laying cycle of laying hens.

Eighth, it can effectively improve the hatching rate of eggs.

Ninth, it can effectively improve the resistance of laying hens and reduce the cost of medicine.
