The morphological differences in the cervical wall and canal between multiparous and nulliparous sows require deep AI devices adapted to the characteristics of the nulliparous.

This second part on AI stud management reviews the procedure for calculating sperm concentration and the elements that affect a correct assessment.
The impact of semen used for post-cervical AI is 2-3 times bigger than that used to produce cervical insemination doses; therefore, preparation of the doses should follow an even stricter control program.
This article lists the critical points that must be considered for a successful post-cervical insemination in sows.
It is necessary to find alternatives to definitely implement this technique in primiparous sows and start its use in gilts.
