Calculate the precise primal breakdown and boneless retail meat yield from a hanging beef side or quarter. Configure quarter selection, hanging weight, cutting style, and carcass fat finish to determine exact weights for chuck, rib, loin, round, ground trim, and bone waste.
Master Rule: A beef carcass divides into approximately 52% forequarter and 48% hindquarter. Boneless retail yield ranges between 60% and 72% of hanging weight depending on trim style and carcass fat cover.

Pasture-raised and pasture-raised carcasses carry leaner subcutaneous fat caps, delivering 4% to 6% higher net lean muscle recovery compared to grain-finished carcasses of identical hanging weight.

Precision Master Protocol
-
1Inspect the chilled carcass at 34 to 38 degrees Fahrenheit to assess subcutaneous fat cover and muscle seam definition before making primary cuts.
-
2Separate forequarter from hindquarter between the 12th and 13th rib, maintaining a clean perpendicular saw cut across the thoracic vertebrae.
-
3Break the forequarter into Chuck (IMPS 113), Rib (IMPS 109), Brisket (IMPS 120), and Shank/Plate following natural connective tissue seams.
-
4Break the hindquarter into Loin (IMPS 173), Sirloin (IMPS 181), Round (IMPS 158), and Flank (IMPS 193), separating the tenderloin muscle intact.
-
5Debone roasts, face steaks to specified thickness, collect clean lean trimmings for 80/20 or 85/15 ground beef, and freeze soup bones separately.
