Introduction

  • Foal heat diarrhea is defined as mild self-limiting diarrhea that is seen in many foals between 5-14 days.

Pathogenesis

Pathophysiology

  • Many causes have been debated and strongyloidosis/changes in milk consumption have been eliminated.
  • It is presumed to be due to development/maturation of the foal's gastrointestinal tract, which may   →   hypersecretion in the small intestine that overwhelms colonic function.
