They often go to surgery because the value of the mare is basically doubled when it has a foal on the ground. Not in the value of the foal but in the value of the mare to be able to take care of that foal. Nursing an orphan is no fun and finding a suitable nurse mare is tricky and expensive.
Any money says that there is a nursemare already well in place. I know over here there are some places that's sole business is to supply nurse mares to large breeding operations if something should happen to the dam.
I'm hoping for a full, speedy recovery. Only the other day I was admiring all the photos of the foal on facebook - amazing how quickly things can change.
