There are enough studies done (mostly TB and WB foals, at least that I’ve seen) showing how freedom of movement in real turnout (ie running bucking farting around) has big implications in structural integrity, compared to stalled horses.
Having any idea that you can expect an athlete, especially a high performance athlete, to be as or more sound, mentally and physically, living mostly in a stall or “stall” to prevent injury, than being allowed to be a horse and do horse things, is beyond me
You simply do not have the same hoof quality, muscle quality, bone quality, and to a lesser extent tendon and ligament quality, in a mostly stalled horse, as you do a mostly turned out (real turnout) horse. Physiology dictates that.
And while many horses are fine, or “fine” living in mare motels, why wouldn’t you want better for them? Mutual rooming is mentally healthy. Playing with others is mentally healthy. Just hanging out nose to tail swishing flies is mentally healthy.
I get it if you choose to have a horse where turnout isn’t an option, * as long as * you make sure that horse gets out and gets moving a good hour a day. I boarded for years where turnout was 1-2 hours a day, 4 on really good days, and I made SURE I did everything I could to go ride every day, hand graze after rides as often as I could, hand graze if riding wasn’t an option, there were just very very few days in a year where JB’s day had nothing but stall and 1-2 hours turnout.
But to decide to do that when turnout is available? No.
Horses are far more likely to be injured when turnout is sporadic, or when they don’t get turnout and are asked to work hard.
And I say this despite having had a horse who was severely injured not once, but twice, while in his freedom of turnout LOL He was also injured a few times while doing stupid things in a stall.
