The treadmill and software cost about $73,000 and are made by SÄTO, a Swedish manufacturer. The endoscopic equipment cost about $76,000. The veterinary school acquired both pieces of equipment and the software through private gifts from individuals and two equine organizations and through funds from pari-mutuel racing. State legislation passed in 1992 authorizing pari-mutuel racing stipulated that a portion of the proceeds support equine research at Purdue.http://www.purdue.edu/UNS/html4ever/9605.Couetil2.html
