Ya know, I'm being a killjoy fuddy-duddy, but it seems to me the elite level in sport has gone as far as it needs to go when we involve animals. A week ago at a 3day, two horses were killed and a rider critically injured. A month ago at Red Hills, same thing-two horses killed, one rider critical. Every year in the Iditarod, an average of 1-2 dogs die. I get the moose thing, but prime dogs are dropping dead in the hours and day after now, as mid-packers are now accomplishing times that were extreme winner times just ten years ago. The bar has been raised over and over and I think it's been raised a tad high.
No, I got no suggestions for a fix...none that can be implemented.
I was thinking about this a lot after it happened. Hope I am not too obnoxious.
They already understand that they are breeding TBs too light now, and also racing them too fast. The horses in those races are juveniles whose bones have not completely hardened. Each time they run micro-fissures occur. In a normal situation, the 2 weeks or so layover between races is enough time to heal these cracks. Some though are over-trained. Someone runs them too fast or hard during breezes or clocked gallops. Often a horse who has not totally healed will just say, "I'm not going," and you lose the race. Eight belles ignored her pain if she was in pain. Under the stress of the race, the legs can shatter. Crucial to this discussion are the drugs they give horses. Bute is a pain killer which dulls the horse's pain allowing him to run, and not to try to protect himself. You find many of the "class dropping" horses drugged up so bad they shouldn't be out there. The owner, usually , is trying to squeeze out as much money as possible, irregardless of whether the horse will die or not.
When ever you run a colt or filly, their legs are at risk. They are trying to get all tracks to change over to the new polytrack. which is safer for the thin legs of the horses. Churchill downs/ Saratoga/ Bellemont resist getting the safe track because of "tradition," even though other tracks like Santa Anita have the Polytrack. Cheaper tracks don't want to go over because they lose their vigorish. It took many deaths to get the NTRA and Jockey club to allow jockeys to wear protective gear, or to use a portion of the tracks take to create an insurance fund. (The average jockey makes about 30 dollars per ride (mount fee) if he/she is not a winner, minus deductions). It's not bad for 2 minutes of work.
Eight Belles was a great filly, but she had genetic unsoundness in her lineage-- I forget the line--Unbridled Song/Northern Dancer. In other words, her lineage is prone to leg-breaks. This is sort of like an Italian Greyhound. They break their legs at a higher rate than other dogs and when young have a very high risk. They put her down, sadly, because the lower legs of a horse are nearly impossible to fix is there is an open wound involved. Like the recent death in the Breeder's Cup Classic, George Washington (the name of the horse) had an open break. He was put down on the track. Barbaro did not have an open break. Barbaro was being kept alive because he could run stud with a gimpy leg no matter what, his running days were over. (He died of lamenitus, not the broken leg). A horse has very little circulation in the lower leg. A break is generally fatal, in any horse-- even pasture grazing mustangs who accidentally trip in a burrow.
She was running against a genetic "freak" named Big Brown. No horse in that entire race could have outrun him because he was of a different "type" of horse. A genetic freak is a different kind of horse. They have a larger heart, better circulation system. Secretariat was a freak. (The kicker here is that Big Brown ran with quarter cracks on his hooves. They too, need repair time. He was running injured during the KD, and will be running injured in the other races. It is highly possible that something will happen to him on the track as well.)
Horses are very single minded when dueling for place in the front of the herd which is what a horse race boils down to. This happens in the wild as well. This is how leadership among horses is determined. On the track, the horses who are all strangers quickly establish a pecking order with the dominant horse taking the lead. A lot of the "horse race" happens in the saddling ring when the horses all see each other.
I don't blame anyone. One horse dies per every 1000 starts. In the History of the Kentucky Derby this was only its second horse death. If I were cold-hearted (which I am not) I would say that these are basically livestock animals and races are run so that they can chose the top sires and broodmares. That is the truth. Its not about how fast a horse goes, it is about who gets the rights to sire the majority of horses from then on in the country. Unfortunately, as with Secretariat, the sort of bigger, tougher horse like Big Brown is a random occurrence.
Eight Belles wanted badly to be the Alpha horse, and she would have been if it was not for Big Brown. Like the Filly Rags to Riches she was the top dog among all those other horses. It is very sad what happened to her, but it was almost inevitable given the variables.
