Three Chimneys Farm has retired Dynaformer after the 27-year-old stallion experienced a cardiac attack on Saturday.
Dynaformer (Roberto) covered 20 mares this year but none of the 13 tested so far have been pronounced in foal. “His heart condition is not uncommon in older horses,” Three Chimneys vet Dr. Jim Morehead said. “Sometimes these conditions deteriorate and further breeding only increases the risk to the horse.”
The Kentucky based veteran is best known for siring 2006 Kentucky Derby winner Barbaro and 2010 Melbourne Cup winner Americain. His latest G1 winner Karlovy Vary claimed the Ashland Stakes at Keeneland on April 7.
Dynaformer began his stallion career at Fox’s Wafare Farm in Kentucky for a $5,000 fee and relocated to Three Chimneys in 1995 where his fee eventually reached $150,000.
Dynaformer has sired 129 stakes winners with progeny earnings of more than $110 million. He had raced as a homebred for Joseph Allen, winning the G2 Jersey Derby and G3 Discovery Handicap under the care of trainer D. Wayne Lukas.
