Do Horizon Organics treat their livestock humanely?

I have been doing some reaserch on humane dairies and what-not. I am a vegetarian, not a vegan. I tried going vegan a while ago, but it was waaayyy too hard, i love my cheese. haha. i just wanted to know if Horizon treats their cows and chickens humanely, because I am more concerned about the animals well-being than my own health (please dont ask me why). thanks.
