I see this argument made about other ruminants and even pigs, but is that the reality? Maybe a pet goat eats the vegetable peels out of the family compost bin, but industrially farmed ones will be eating corn-based feed that was specifically grown for the purpose, on land that could grow anything.
Go look at satellite imagery of the Israel-Egypt border. The Egyptians herd goats in the area, the Israelis do not.
You can clearly see the lighter shade of the Egyptian land, because the goats strip it clean. That is mountainous land that has no value for farming, but the goats can roam it and eat anything that happens to grow.

Not sure how goat farming works, but AFAIK for cows they spend the first half of their lives on pasture (ie. eating grass) and the rest on feetlots (ie. eating corn).
