A free live webcast will be offered at 1 p.m. EDT, July 28 to address one of the most puzzling disorders in horses.

"Shivers" is a disorder in horses that has been recognized for centuries. It's also been puzzling equine experts for just as long. Shivers is considered both common and rare, affects both genders, appears at all ages, and is principally reported in draft horse breeds.

The webcast, offered by My Horse University and the University of Minnesota Horse Extension Program, will focus on shivers and other equine muscle diseases. Participants may register online for the live presentation, during which they can ask questions on this topic. Recent advances in genetic research will be highlighted. Presented by Stephanie Valberg, professor and director of the University of Minnesota Equine Center, "Shivers and Other Muscular Diseases" will review the variety of symptoms that occur with shivers, the progression of symptoms and possible causes.

The webcast is the third in a series titled, "Equine Genetics: A New Diagnostic Resource for Horse Owners," and is funded by a grant from the U.S. Department of Agriculture�s National Research Initiative. Future programs will focus on managing equine metabolic syndrome and advances in equine genetics
