I will assume she is a dairy breed. You will never "finish" her at 600 pounds. The only way to get well marbled meat with a decent bone out yield from that small of an animal is to make her milk fed veal. Outside of that, she will be putting energy and protein to frame development.
You can cut her down to 12% total dietary protein and gradually increase starch(corn) content while reducing the forage:concentrate ratio to increase fattening, but you will need to walk the tight rope of sub-acute ruminal acidosis to get any kind of marbling into a dairy freemartin at only 600 lbs. Fat Holstein steers can be fed corn silage, high moisture shelled corn, and SBM along with other commodities and additives and yield choice and hit 62-65% yield at 1150-1200 pounds with hard core intensive feedlot management. The old grain and hay regimen meant 1600-1750 lb Holstein steers at finish.
Have you ever thought of selling her and buying back feeder lambs? Smaller cuts and easier to get grade on dry hay and grain or grass? Or swap someone who has larger animals raised the way you like, trade the heifer for pounds of finished meat from another producer?
