One of the most important complications in neonatal foals is failure of passive transfer: the inadequate absorption of antibodies from the mare’s colostrum. Approximately 5-20 percent of newborn foals are diagnosed with FPT and are at risk for developing serious medical conditions.

To learn why passive transfer is so critical and how to prevent it from happening in your foal, follow the steps illustrated in this infographic, from broodmare vaccination to supplemental colostrum administration.

With a visual understanding of how your newborn’s immune system functions, you can work with your veterinarian to prepare for foaling and ensure your foal receives the protection he needs.
