Grasping the best insemination time, correctly finding the estrus in the sow, and accurately grasping the best timing of sow conception are the key to ensuring the success or failure of the sow. The sow's estrus is generally changed from excitement to trance. When the back is pressed, there is static reflection. The mucus of the cough becomes thin and viscous. This is the timing of the first insemination. If you can accurately grasp the timing of insemination only once can guarantee a good conception rate and birth rate. The second insemination is the guarantee factor for increasing the conception. The interval time is 12 hours for sows and 12-18 hours for sows. In the production process, attention should be paid to the first insemination, multiple inseminations should be avoided, and the inability to express sperm immediately after weaning is reflected more than one week after weaning. Sows avoid access to boars or scent of boars at least one hour before insemination, which can avoid the sow's excitability and adversely affect sperm insemination and conception. For sows that return, they can be rushed to the boar bar and exposed to boars. Two times a day, the sow insemination every 5 min should not be subjected to external stress. The fertilization process is a complex physiological process. The uterus and fallopian tubes move in accordance with certain laws together with hormones and nerves to promote the combined operation and implantation of sperms and eggs. As a result, sows are bred in a single bar during insemination, providing a comfortable and quiet environment. On the other hand, the time of insemination should soothe the sow, and the movement should not be rough and oversight, and prevent the sow from being over-stretched. The insemination process takes 3 to 10 minutes.
