When pigs are artificially inseminated, it is said that when they are inserted into the sow's vulva, they are most likely to get sick. How is this right and what is wrong?

First of all, we should go to the boar to take out the sperm, freeze it at 0 degrees, inhale the semen into the syringe, put a latex tube in front of the syringe and cover it at the front of the syringe.

When fertilizing sows, insert the tube at the front end of the syringe into the sow's vagina, 15 to 20 cm deep, then start pushing the syringe and slowly inject semen.

The insertion depth of latex tube depends on the size of sow. Sows weighing about 200 kg are between 20 cm and 30 cm, so they need to be inserted slowly, not forcibly and casually, so as not to be damaged.

Latex tube and syringe must be strictly disinfected and used for the last time. It is sold in a medical equipment store.
