Research at the University of Minnesota College of Veterinary Medicine indicates that administering a high dose of oxytocin to sows 12 to 20 hours after farrowing can significantly improve colostrum quality and passive transfer of immunity. For producers, improving early passive transfer can reduce pre-weaning mortality, lower disease treatment costs, and improve overall herd health.
In a controlled field trial involving 96 sows, piglets from sows treated with oxytocin showed better passive transfer of immunity, which is crucial for survival and early growth.

This study also demonstrates that oxytocin can deliver a measurable benefit even under real-world variability, which is encouraging for practical on-farm application.” – Bryn Anderson
