This subject just tears me up. Years ago, I once considered bringing a horse to an action as I had him listed for sale and I was not getting many inquiries. I had already found a new prospect and was preparing to move him into the stable, not wanting to pay to stable two horses, I googled horse auction and all of this information about horse slaughter came up, I was mortified and resolved to hold onto the horse and continue paying board until I found a suitable home for him.
The problem has not gone away, it's just been pushed to over the boarder. You can outlaw the auction but never get rid of the outlaw.
