What should you watch out for when sows are being artificially inseminated?

(1) Use a needle to make a small hole in the bottom of the infusion bottle, stroke the sow's breast or vulva, press the back of the sow, and make the uterus contract to produce negative pressure, and inhale the semen. (2) Control the infusion bottle's level to adjust the insemination time. The insemination time should be 3 to 5 minutes. After the infusion is completed, the back end of the vas deferens should be folded in a small section to prevent the air from entering the sow's reproductive tract. Place it in the infusion bottle to allow it to stay in the genital tract for 3 to 5 minutes, allowing the vas deferens to slip slowly. The first step: the time spent in insemination should not be less than 5 minutes, insemination is too fast, semen may have been reversed. It is best not to exceed 10 minutes. If it exceeds minutes, there is a problem with the sperm delivery process. (3) Sows should avoid nearing boars or smelling boars for at least one hour before insemination, so as to avoid adverse effects on insemination and abortion after sows are highly excited and nervous. (4) The rate of insemination should be appropriate. Excessive insemination may return semen a few minutes or ten minutes after insemination. (5) Any stress factors before and after insemination will have an adverse effect on fertilization. Don't beat the sow's buttocks after insemination. After sowing, sow the sow's buttocks so that the sow's muscles contract, and temporarily avoid semen backflow. But after being frightened, the body will release epinephrine and engage in reproductive hormones such as oxytocin. It will weaken the uterine contraction wave, affecting the operation of the semen to the deep part of the uterus and adversely affect the fertilization of the egg. (6) If semen flow is large, insemination should be repeated. A large amount of semen backflow does not ensure the total amount of semen entering the uterus. Therefore, the insemination process should be reviewed so that the sow can rest after two hours of rest. (7) After the insemination, the sow should be avoided within 10 minutes. It is best to avoid the sow drinking too cold water. Under the sow, the sow’s abdominal pressure increases, which can easily cause semen backflow. If the sow should lie down, it should be driven away, but it should not be treated harshly to avoid stress. Drinking cold water may stimulate gastrointestinal and uterine contractions. Cause semen backflow.
