Correct and standardized insemination methods can significantly improve the conception rate and litter size of sows and increase the economic benefits of the farm. Therefore, farmers should master the insemination technology. 1. Carefully examine semen before insemination and record in detail. 2. On the scale pig farm, the boar arrives on the field 10 minutes in advance to stimulate the sow sufficiently to promote the maturation of follicles and the discharge of secretions. 3. The estrus treatment of estrus sows should be conducted in accordance with the principle of “one scrubbing, two sterilizing and three rinsingâ€, and then artificial insemination. Observe the performance of sows carefully during insemination, and record the details of each sow (whether or not to stand still, There is no backflow of semen, and the front of the vas deferens is locked.

The boar must go to the scene when the sow is inseminated, requiring each pig to inseminate for 3 to 8 minutes. Each semen is lost 3 to 5 times. 4. If the gilts or abnormal estrus pigs have too fast self-absorption of sperm during the insemination process, proper adjustments should be made to the suspension height of the vas deferens and bagged semen. Sufficient patience, speed, and accuracy are required. And quality. 5. After insemination, the boar needs to stay in the sow room for 5 minutes to stimulate the sow to better absorb semen. 6. For sows with 1 to 2 parity litters, not only should the estrus identification and timing of insemination be taken into account, but also the operation of the previous fetal insemination personnel.
