The three key techniques of artificial insemination, this article is very thorough!

Key Technique 3: Operation Details after Insemination

Continue to massage the sow for 1-10 minutes after insemination. The vas deferens should not be pulled out immediately. Let the vas deferens stay in the sow uterus for about 10 minutes, or wait for it to slide naturally to prevent semen backflow. But also should not stay too long, lest vas deferens cause damage to uterus. At this time, in order to prevent air from entering the reproductive tract of the sow, the rear end of the vas deferens is folded and inserted into the sperm bottle.

When sows enter embryo implantation period after insemination, severe stress should be prevented, sows should be kept quiet, whipping and chasing sows are strictly prohibited, so as to avoid early embryo death caused by sow stress.

Generally, within 30 days after breeding, do not adjust the fence at will to reduce stress such as high temperature, high humidity and immunity. Do a good job in the 18-65 days after breeding recurrence inspection work, identified as empty pregnant, return to estrus sow only need to catch up with the pen in time to concentrate on feeding, compound or eliminate.

Embryo implantation is the key time to ensure conception, this time, feed can not be fed too much (usually 70%-80%), limit feed energy, protein intake, if too much heat, will burn a part of semen. At the same time to do a good job of management, do not give sow too much stress, feed pigs when feeding this batch of pigs first. For the use of vaccines, pig B indicates that it is best to fight after the transition period of embryo implantation.

To control the temperature and humidity according to different varieties, keep the pens dry. Don't often rush fence, lest the ground is wet, too slippery harm to sow.
