what is the process of horse slaughter?
<answer> From the holding pens, horses are eventually herded through narrow alleys into the kill chutes. In some plants, a captive bolt gun is used to drive a metal rod into the horse's brain to paralyze (but not kill) the horse. <context> The Slaughter Process.
