The last foal birthed by champion racehorse Black Caviar has died just a day after being born.

The 18-year-old mare died on Saturday shortly after giving birth to her ninth foal in 11 years.

Black Caviar’s connections released a statement on Monday advising that the foal had died on Sunday night.

“He received around the clock, world-class veterinary care but unfortunately could not be saved,” the statement said.

“The ownership group would like to thank the entire veterinary team who dedicated their time and efforts to caring for Black Caviar and her colt.

“The ownership group would also like to acknowledge and thank the Australian public and the racing public globally for the many tributes to Black Caviar. She was much loved and admired.”

Black Caviar’s former trainer revealed Black Caviar was euthanased on humane grounds after succumbing to laminitis, an incurable disease of the foot that eventually becomes so painful that a horse can no longer walk.
