41 minutes ago, Margaret Pilgrim said:I can't speak to Costso's possible use of dairy cattle, but FWIW, both in Europe (started in Spain with retired farm oxen) and from premium beef suppliers, male dairy breeds are chosen and raised for their superior beef. See Flannery Beef.
I have no idea how this compares to or is even similar to Costco prime beef.
The point someone was making about grading beef (if I understood it) was that there are a lot of different kinds of cattle available now and there was basically only one when the USDA grading system was established and the result today is a lot of all different kinds of beef being graded by only one standard. For instance, the grade of the whole cow is determined by the amount of fat in some particular rib (3rd or 4th?)in the cow
