I'm interested in sourcing some (fairly significant) quantities of milk, and I'd obviously like it to be grass fed/pastured. (I don't much care if it's raw: I'm unconvinced of the health benefits and don't feel like eating the cost/storage difficulties.) I've found a number of places that claim cows get significantly amount of pasture, but also eat:
The cows' supplemental feed consists of alfalfa, corn, barley meal, mineral supplements and protein meal (the protein meal is sourced from flax, canola or sunflower when available; soy is only used when the other three are not available, and even then the soy is non-GMO and grown in the U.S.). The corn is grown on the farm, and overall, 75% of the feed is grown in Oregon!

Would you guys be willing to drink this? Any evidence what the fat breakdown on such milk would look like?
