I always see my stock through the slaughtering be they my own or those that I manage, so know how they are treated, I take the wild boar through myself as they know me and will not suddenly become agitated surrounded by strangers. Any stock for personal use and not for sale I slaughter myself at home, an old tin bathtub with a winch works well as a scalding tank, boil water on a wood stove or in a metal drum over a fire outside, pour over using a jug, and use tin lids to scrape off the hair, this has worked for me for over 30 years, and with my training in meat inspection I am able to produce neat joints and chops for my own or for any neighbours I help.
