The Society of International Thoroughbred Auctioneers has adopted new guidelines that will effectively ban the sale of broodmares 18 years old or older, or mares who have been barren for three consecutive years at the world's major auction houses. Such mares can still be sold under special circumstances.\nIn its annual meeting last month in England, members of the auctioneers' association voted to adopt the policy formally, though several American auction houses already were discouraging the sale of such mares. The policy does allow sales companies to use their discretion regarding older barren mares consigned as part of major dispersals.\nThe guidelines were based on concern for the horses' welfare, said Keeneland's sales director, Geoffrey Russell.\n"It's our policy already as one of our conditions in the consignor's contract," Russell said. "We have waived it, and I think we would probably continue to consider that for dispersals.\n"There are two issues. First, it is for horses' welfare. The stress of going through a sale is tough on any horse, and for an older horse it would be tougher. And the second thing is the market. Who are you going to sell it to? So are you going to go through this exercise and not get it done anyway and put the horse through all that?"\nFasig-Tipton's president, Boyd Browning, said his company had "discouraged" consignors from entering older or repeatedly barren mares but did not have a formal policy in place until now.\n"This formalizes the approach," Browning said. "I think it's indicative of the heightened awareness and concern, making sure there aren't unwanted horses going through the auction ring and that horses get treated with respect and dignity throughout their entire career. I think there's a fairly efficient marketplace privately [for these horses]. One thing about capitalism is that opportunities and markets will tend to emerge, and I think there will be plenty of other opportunities to sell these horses privately."\nBig holiday weekend\nThe recent holiday weekend was a big one for three central Kentucky sires. Dynaformer, Speightstown, and first-crop sire Roman Ruler each had two or more winners on Sunday at racecourses from Europe to California.\nDynaformer, a 24-year-old Roberto horse, got two high-class winners in Gozzip Girl and Wiener Walzer. Gozzip Girl, a Stonestreet-bred daughter of the Kingmambo mare Temperence Gift, won the Grade 1 American Oaks Invitational at Hollywood Park. Hours earlier, Wiener Walzer had taken the Group 1 Deutsches Derby in Hamburg, Germany. Wiener Walzer was bred in Germany from another Kingmambo mare, Walzerkoenigin. Dynaformer stands at Three Chimneys Farm for a $150,000 fee this year.\nSpeightstown also had a pair of winners on Sunday. An 11-year-old Gone West stallion, he got his first Grade 1 or Group 1 winner when Lord Shanakill scored in the Prix Jean Prat in France. Later that day, Munnings won the Grade 2 Tom Fool at Belmont. Lord Shanakill is out of the Theatrical mare Green Room and his breeders are Vimal and Gillian Khosla and Templeton Stud. Dan Tayloe and Glencrest Farm bred Munnings from the Holy Bull mare La Comete.\nSpeightstown was North America's champion sprinter in 2004 and stands for $35,000 at WinStar Farm.\nHill 'n' Dale Farms resident Roman Ruler had three juvenile winners coast-to-coast on Sunday. A 7-year-old son of Fusaichi Pegasus, he sired Rickyontherun, a winner in maiden claiming company at Delaware Park; Vivid Colors, an easy winner in the slop in a Churchill maiden special weight race; and Roman Counsel, victorious in another maiden special weight contest at Hollywood.\nRickyontherun is out of the Tabasco Cat mare Cateress and was bred by Gulf Coast Farms. Bred by Jerry Jamgotchian, Vivid Colors is a filly out of Scene Maker, by Unbridled's Song. Sunset Stables bred Roman Counsel from the Swiss Yodeler broodmare Marie's Rose.\nRoman Ruler stands for $20,000 this year.\nMare registration due by Aug. 1\nThe registration deadline for registering mares bred in 2009 with the Kentucky Thoroughbred Breeders' Incentive Fund remains Aug. 1.\nTo qualify, mares must have been bred this year to a Kentucky stallion and remain in the state from covering to foaling.
