PCAI that pays off: better results, smarter use of semen

A recent study in Scientific Reports compared post-cervical artificial insemination (PCAI) with conventional cervical insemination in 716 gilts and sows under subtropical climate conditions (study link). The findings are clear: when catheterization is successful, PCAI reduces semen backflow, shortens insemination time, and enables a significant reduction in the sperm dose while maintaining or improving reproductive performance in both gilts and sows. The authors also emphasize that catheter design, device quality, and correct handling are key factors influencing PCAI success. This is precisely where Minitube PCAI catheters excel.

What the study found 

• Compared with conventional cervical insemination, PCAI achieved the following:
• Higher non-return and farrowing rates in both gilts and sows
• Better litter outcomes (total born, born alive, and weaned litter size), especially at reduced semen doses
• Less semen backflow, which reduces sperm loss during the procedure
• Shorter infusion and total insemination time in sows, which supports more efficient daily routines
• Consistent results across sows, including gilts, which are traditionally more challenging

What this means for farms

The study's benefits are only fully realized when catheterization is performed reliably. The Minitube PCAI catheters that were used in this study are specifically developed to support exactly that:

• More doses per ejaculate: Minitube PCAI catheters enable reliable insemination at significantly reduced sperm doses, making better use of every ejaculate and improving semen utilization across the herd
• Maintained or improved reproductive performance: With successful catheter placement, farms can achieve strong non-return rates, farrowing rates, and litter sizes, even when sperm doses are reduced
• Less semen waste: Post-cervical deposition with Minitube catheters significantly reduces backflow, minimizing sperm loss at every insemination
• Faster, more efficient workflows: Shorter infusion and total procedure times translate directly into more efficient routines in the breeding unit
• Reliable results in gilts and sows: Minitube's catheter design supports successful placement in both parity groups, including the more demanding gilt population
• Support for genetic progress: Lower-dose strategies become practical, enabling the wider use of high-genetic-value boars and more cost-effective breeding programs

Scientific evidence confirms it: PCAI improves reproductive performance, reduces semen loss, and shortens procedure time, even when using lower doses of sperm. However, these advantages depend on successful catheterization. Minitube PCAI catheters are designed to deliver exactly that: controlled, reliable post-cervical deposition, consistently and efficiently, in every routine.
