Grassfed in large scale takes away needed grass from the national brood cow herd thus producing less calves. If you had a calf to finish grass operation i would suspect you would have to cut your brood cow herd by about 40%. i doubt that you could come out finacially against feedlot even with high corn prices. The reality is we went to the feedlot because it was more economical. That hasn't changed and we need the beef produced as fast as possible not sitting around eating up needed pasture for an extra 6-12 months.
