It really depends on what company you are buying from. Horizon dairy is the largest organic dairy source, and many "store brand" organic dairy products are actually Horizon. They take a pretty large scale, factory farming approach to their business, and I do not feel they treat the cattle nearly as well as they should.
Organic Valley is a better option: they are owned by all of their family farmers, and have much higher standards than Horizon.
