Post-cervical insemination is an insemination technique that is in continuous growth, being the most common in the European markets.

This insemination method, as its name suggests, consists of depositing the contents of the seminal dose through the use of a probe in the body of the uterus. This method is particularly useful in sows that have had problems of cervical regression or in those cases where traditional methods can be complicated or very ineffective.

The application of this technique has a number of advantages that allow for increased productivity:

  • The reduction of the volume and concentration used increases the number of seminal doses produced per boar, obtaining a higher yield of those with higher genetic value and improving parameters such as transformation index, growth speed and homogeneity of the offspring.
  • It facilitates management by reducing the time per sow inseminated, since with traditional insemination the average time spent is 5 to 10 minutes, while for post-cervical insemination it is 1 to 2 minutes.
  • It allows us to observe each insemination individually from beginning to end, which gives us greater certainty as to whether the sow has been properly inseminated or not.
  • The fact of depositing the semen in the body of the uterus reduces the occurrence of reflux during insemination.

This technique is more complex than the traditional one and needs specialized material to develop it. The post cervical probe must fulfill a series of characteristics for the insemination to be successful. This probe must be sufficiently rigid so that it can penetrate without difficulty, and at the same time it must be flexible so that it bends in case the probe does not progress and does not injure the sow.

Post-cervical insemination to increase productivity

At Magapor we have developed our post-cervical insemination probes taking into account the reproductive system of the sow. The length of the probes must vary between multiparous and nulliparous sows, since their reproductive apparatus is different. For the development of these specific probes for gilts, we collaborated with the University of Zaragoza and carried out the study of more than 600 reproductive apparatuses of gilts, guaranteeing a design based on the anatomy and adapted to the maximum.

Benefits of the Nulliparous Probe:

  • Facilitates insemination in gilts, especially those that have not farrowed.
  • Its design allows a more comfortable procedure, reducing the risk of errors and damage.
  • Increases the probability of success in the insemination of gilts, thus optimizing production.

Post-cervical insemination is somewhat more complex than traditional insemination, however, it presents multiple benefits. Through training and the use of appropriate materials to implement this technique, a significant improvement in farm productivity can be achieved.
