Not sure why you would say such a thing, but it's not true. Anyone can have a cow, or 5 , butchered. In most freezer beef sales, the live animal is sold, then butchered and the customer picks up the meat. It's very common.
The "grass fed" stuff is just another sales gimmick preying on unsuspecting folks. All beef cows are grass fed, every single one of them. There are a few, very few, farmers that grass finish animals. But, the vast majority claiming "grass fed" are just pulling animals of pasture (too early) and slaughtering, then charging higher prices for it. It's in no way healthier or better tasting than grain finished. In fact, some of it's downright poor. There is a reason the USDA grading system is based on fat content, it's the taste the most people prefer.
BTW, I did look up Polyface Farms. Just as I suspected, using scare tactics and degrading remarks towards other farmers, some not true, to gain sales. If the product was that good, those methods shouldn't be necessary. Tells me something about their charator as well.
Excellent points.
