Do they eat them?

Yeah, when they sober up from the high of slaughtering them.

All that matters is if they use Hickory or Mesquite.

Do they eat them?

From the article:

The slaughtered animals are taken back by devotees to their villages and eaten during a feast.

So basically they kill a bunch of animals and eat them during this religious holiday which occurs every five years. Personally, the notion of animal sacrifice in religion seems repugnant to me - but killing and eating livestock isn't much of a story.
