Comparing grain and soy fed factory farmed cows with grassfed organic dairy cows* wouldn't even prove that for cows, though. It could just be a function of the different feedstocks. It also wouldn't apply to US production, as US cows in organic dairy production are mostly fed on grain and soy (most US organic dairy is actually factory farmed, just with organic feed and no routine antibiotics) rather than grass.

*It's also important to note that any organic milk you buy in the store in the US almost certainly comes from a grain/soy fed, factory farmed animal, not one fed mostly on grass. US organic standards do not require access to pasture or forbid factory farming methods.
