Moldy or Dusty Hay, Heaves, and Horses
  by Robert N. Oglesby DVM


Introduction » Hay Molds and Heaves » Detecting Mold Spores in Hay » Prevention » The only hay available is smoky! » More Info 

It is just a fact of life that all baled hay develops some amount of mold. In well put up hay, hay that is suitable for horses, the amount is undetectable. However, if hay is bailee before it is adequately dry or becomes wet during storage, molds flourish producing large numbers of spores. Chronic exposure to large amounts of mold spores causes a serious allergic condition in horses called heaves or chronic obstructive pulmonary disease.
