THE world's greatest racehorse Black Caviar has been retired after winning just under $8 million in prize money, including 15 Group One victories.
The owners of Australia's greatest mare announced a short time ago they had had decided against racing her on, but will instead begin a breeding career for her.
Her foals could fetch millions if put up for sale, the ABC reported.
Black Caviar has been unbeaten in 25 starts.
"The owners and myself have had a long chat for past couple of days [and] this afternoon at lunchtime we decided 25 was a great number," trainer Peter Moody said.
"Collectively we decided the mare's in great shape, we thought long and hard about racing at the international season."
Moody said Black Caviar would be taken to Caulfield on Saturday to give the Australian public a chance to farewell her.
Then she would "go to a farm, have a relax and a roll around in the mud''.
"She's in such great shape but that's always been the way we wanted her to bow out," Moody said.
Black Caviar's win on Saturday in the TJ Smith Stakes on Saturday in front of a capacity crowd at Sydney's Randwick racecourse was her last hurrah.
Her phenomenal run has resulted in a resurgence in interest in racing, filling the stands everywhere she went.
Her feats on Australian racetracks are unsurpassed.
Her latest victory at Randwick saw her eclipse the previous record of 14 Group One wins held by Kingston Town.
Black Caviar bought for princely sum of $210,000
Black Caviar was born on the 18th of August 2006 at 5.20am at Gilgai Farm in Nagambie, Victoria.
She grew up on the Goulburn River property and then went to Swettenham Stud in December 2007, for a 10-week yearling preparation where she was then sold on behalf of Rick Jamieson to Peter Moody for $210,000 at the Melbourne Premier Yearling Sale.
She is owned by G. J. Wilkie, K. J. Wilkie, Werrett Bloodstock Pty Ltd, C. H. Madden, J. Madden, P. A. Hawkes, D. M. Taylor and J. Taylor.
She was sired by Bel Esprit, winner of the Doomben 10,000 which also sired Bel Mer, a mare that won the Robert Sangster Stakes in 2009.
Black Caviar was the first foal of her unraced dam Helsinge, a daughter of the British racehorse Desert Sun, who never won a major race but was placed in the Craven Stakes and the Sandown Mile.
Desert Sun also sired the outstanding racemare Sunline.
Helsinge is also the dam of All Too Hard, winner of the 2013 C F Orr Stakes, the 2012 Caulfield Guineas and runner-up in the 2012 Cox Plate.
As a descendant of the British broodmare Pinprick, Black Caviar is a product of the same branch of Thoroughbred family 1-p, which also produced the Classic winners Ambiguity and Sodium.
Black Caviar weighs approximately 570 kilograms and stands 16.2 hands high.
