I read yesterday that his back leg isn't likely to be able to bear his weight to be used as a stud.
And second, Barbaro is insured for around $30 million. So there is a financial incentive of around $20-30 million to keep this horse alive.
Which means they could have had him destroyed on the track and collected 30$ mil.
"Which means they could have had him destroyed on the track and collected 30$ mil."
If I recall, jockey/actor Gary Stevens said he was surprised they hadn't done that, and it was a tribute to the Jacksons that they were going to try to get Barbaro repaired.
In any case it's believed that the insurance policy is for inability to stud, not necessarily mortal injury or death.
