This study evaluated innovations in beef wholesale carcass fabrication that may
have potential for improving subprimal yield and overall value of the beef carcass.
Thirty beef carcasses, equally representing USDA Choice and Select and USDA yield
grade 1 and 2, were selected from a commercial processing facility and transported to
Texas A&M University for subsequent fabrication. Beef sides were utilized in
comparing a conventional carcass fabrication style to a more innovative method.
Innovative forequarter subprimal yields were greater (P < 0.001) for the brisket, ribeye
roll, blade meat, and back ribs. The innovative method resulted in greater subprimal
yield and less lean trim (P < 0.001) from the forequarter. Innovative hindquarter
subprimal yields were greater (P < 0.001) for the tenderloin, top sirloin cap, bottom
sirloin tri-tip, and round tip. Hindquarter subprimal yield and lean trim were not
affected (P > 0.05). Value was greater for the innovative forequarter (P < 0.001) and
hindquarter (P < 0.01); value was increased by more than seven dollars per beef side,
thus greater than fourteen dollars per beef carcass. Selected subprimals were evaluated
in a retail cutting test. Experienced retail professionals were utilized in fabricating the
retail cuts. In general, the innovative retail subprimals performed equally or better than
the conventional subprimals. The M. Serratus ventralis fabricated from the innovative
side, comprising over 4.5% of the innovative forequarter, generated greater than 57%
steak yield and 94% saleable yield. Innovative carcass fabrication techniques resulted in
greater subprimal yield and increased the value of the entire beef carcass. These results
were verified by retail cutting tests conducted on selected subprimals.
