What exactly is founder and how can it be prevented? -Greening Up Fast Dear Reader, Founder is a very serious condition in the horse whichcauses mild to severe pain, most commonly in the front feet but itcould be all four feet. It is also commonly referred to as laminitis.This term means inflammation of the laminae, which are two highlyfolded tissue layers that secure the inside of the hoof wall to thecoffin bone. Laminitis results from a disruption in blood flow tothese laminae which weaken them and allows the tissue to rip and tearas the coffin bone pulls away. Laminitis is known to occur secondary to a variety of diseases, such asPotomac Horse Fever, retained placentas, and some respiratoryinfections. Too much grain or lush grass high in fructose are probablythe most common causes, followed closely by endocrine diseases likeCushings Disease and equine metabolic syndrome. A type of laminitisreferred to as road founder is caused by excessive concussive impactto the feet, especially on hard surfaces. Support limb laminitisoccurs from excessive weight bearing on one leg due to the injury ofanother leg. Bedding that contains black walnut shavings has also beenknown to founder a horse. A horse that is suffering from an acute laminitis episode will walkvery stiffly. They may have a hesitant gait, as if walking oneggshells. Horses in severe pain will rock back on their hind limbs,positioning the front feet out forward to relieve pressure. This isreferred to as a saw horse stance. An increased digital pulse at thepastern, heat in the hoof wall and coronary band, and pain at the toeregion when pressure is applied with hoof testers are all signs ofacute laminitis. A chronic or long standing laminitic horse mayexhibit horizontal rings in the hoof wall, bruising of the sole whenpared away with a hoof knife, a widened white line or seedy toe anddished out hooves (Aladdin slipper appearance). If you see any of the symptoms of an acute laminitis, call yourveterinarian immediately. The sooner treatment can be initiated; thebetter off your horse will be in the long run and the less damage doneto the feet. Immediate treatment focuses on reducing inflammation andsupporting the coffin bone inside the hoof. Banamine or Bute,intravenous DMSO, and soaking the feet in ice water will help with theinflammation. Deep, soft sand is the best support for the frog andsole. If this is not available, one inch thick construction insulationcan be cut out to fit the foot and taped on. Eventually, your farriercan help with long term options for shoeing support.The best way to avoid laminitis is to prevent causes that are underyour control. Keep grain stored securely, introduce your horse to lushpasture gradually, and feed a low carbohydrate diet. -Dr. Wade Hammond 4 5 7 ?
