There has been no improvement in the condition of Black Caviar’s half-brother who vets give no more than a 50-50 chance of surviving laminitis.

Grave concerns are held for the colt’s welfare as he faces a crucial 48 hour period over the weekend at the Werribee Veterinary Clinic.  He is receiving powerful painkillers and has been fitted with special boots for both forelegs.

BC3 Thoroughbreds paid an Australian record $5 million at the 2013 Inglis Easter yearling sale for the Redoute’s Choice colt who is a younger half-brother to Black Caviar.

BC3 issued an update following an adverse reaction to antibiotics administered after a spider bite.  “He remains stable and comfortable, surrounded by the best veterinary team at Werribee,” BC3 said in a statement on Friday.  “We will now play the waiting game – our focus is on giving him every chance.”

The colt they call ‘Jimmy’ remains a stallion proposition, even if he doesn’t race.

Apart from a world-beater, his dam Helsinge also foaled Australian 3YO Champion All Too Hard (Casino Prince) who is serving a full book first-up at Vinery for a $66,000 fee.

Another son Moshe (Bel Esprit) is currently in his second year at Eliza Park Stud.  He won three races in Victoria but was unplaced at his only attempt in black-time company.  His first book in 2012 comprised 174 mares at a $6,600 fee.

Helsinge is owned by Gilgai Farm’s Rick Jamieson and she has an unraced Redoute’s Choice 3yo named Belle Couture.  The filly is with Danny O’Brien at Flemington and is expected to kick off her career this summer.

After Jimmy, the mare has a yearling filly by Bel Esprit and she foaled a Casino Prince filly in October.
