Artificial insemination breeders are caged. Since the range of activities within the cage is small and it is easy to cause fat deposition, it is necessary to strictly limit the feeding amount according to the weight gain condition of the chicken to prevent the formation of fatty liver and the occurrence of prolapse of the anus, otherwise it is not conducive to the extraction of the rooster and the hens.

In the two weeks before insemination, the proposed rooster should be collected and refined so as to form a good conditioned reflex on the Baoding, massage and ejaculation process, and to understand the sex reflex habits of each rooster.

If the massage time is too long or the force is too great, the cock will develop counter-stimulation without sexual reflex, or it will pollute the semen due to defecation and damage to mucous membranes; if the force is too small, the evacuation of the dispenser is not sufficient and it is easy to retract. When the sperm is collected, neither the finger nor the collection cup can touch the dispenser. A cock should be used with a collection cup. After collection, the semen should be combined with a dropper to prevent the unclean semen from affecting the quality of the entire cup. Semen contaminated by feces should be discarded.
