It is not necessary for animals to suffer while being raised for meat. In fact, proper animal husbandry does just the opposite by making the well-being of the animals the highest priority. A good husbandman nurtures animals, giving them the best living conditions possible. In return, the animals nurture the farm ecosystem. While its true that even the best system isn't perfect, with proper care we can come very close. A factory farmer, on the other hand, exploits animals, leveraging confinement systems that cause massive amounts of unnecessary suffering.
