I'm not sure that your respect isn't at least somewhat misplaced. If Barbaro recovers, his owners will make the vet bills back in stud fees within a year.
It is unlikely that Barbaro will ever be a stud horse. The governing association requires the stud to "cover" during fertilization. The doctors believe that his leg will never have the integrity to support the weight. This additional setback doesn't help.
It is not 100% that he will be able to stud....that is rather violent event and I am not sure his front end will be able to handle it....IMO
