If the horse is impure, overbred, or inbred or has broken lines they should go to the slaghter hose. {In rl I whould Happily brun all the slaughter houses} But the pure ones get bought by them too. They end up at a higher price that is true. But you also have like a week to reclame your horse. Its your falt if your horse gets sent to the HS. If you want them to rase the price it will coast more for you aswell. Most slaughter houses go up to 2k for buying horses. It wont stop them....
