ARCADIA, Calif. - Bertrando, the champion older male of 1993 and a leading stallion in California in recent years, is suffering from a liver disease that could lead to him being pensioned after the current breeding season, owner Marty Wygod said.
In December, Bertrando underwent surgery for the second time to remove gallstones, a rare occurrence for Thoroughbreds, according to Greg Ferraro of the Center for Equine Health at the University of California-Davis. The chronic liver disease caused the stones, Ferraro said.
