There are some extremely relevant and notable moral differences between someone defending their own life from a threat, and raising a lamb in a cage so small that it cannot turn around, forcing it to drink it's own urine in a desperate attempt to recycle the little iron it has in it's system (gotta keep the meat anemic and tender!), before stunning it with a bolt gun and slitting it's throat. All because you enjoy the taste.
It is not a case of having different values. It is a case of being socialized from a young age to disregard the wellbeing of certain animals. The values are fundamentally the same.
