Parasite management helps to keep horses healthy  

While parasites are a normal part of the intestinal flora of the horse, at times, some parasites can cause disease unless the horses receive routine preventative treatments. An equine intestinal parasite management program should include regular veterinary care, diagnostics, targeted use of easy-to-administer dewormers, effectiveness monitoring and appropriate pasture management.
