In Italy we eat horses, so they are also farmed for food. I bet all the horses that end up on a slice of bread or a pizza would rather have pulled a carriage. Still they are a much less popular meat, I don’t think horse farming is as bad as, say, pig farming, (for the horse I mean) because there’s much less demand. “Frayed threads” (lack of better translation) of horse are pretty good with olive oil btw.
