The pregnant mare and her foal have unique healthcare needs. Caring for these two unique classes of equines is completely different from any other horse. Different vaccinations, different deworming schedules, different nutritional needs - just to name a few.

The Merck Animal Health Mare and Foal Care program is a comprehensive guide to healthcare from pre-breeding through the foal's first birthday.
