A method for mass-production butchering of a chuck roll of beef includes: sectioning the chuck roll anterior to and generally parallel to the first rib to separate a neck portion thereof from a remainder thereof; sectioning the remainder into a first portion and a second portion substantially along a natural seam, the first portion comprising rhomboideus, spinalis dorsi, and serratus ventralis muscles, and the second portion comprising multifidus dorsi, complexus, and longissimus dorsi muscles; sectioning the first portion to substantially remove the rhomboideus and the spinalis dorsi therefrom, leaving a denuded serratus ventralis; sectioning the serratus ventralis into a first set of separate portions. The method may further include: sectioning the second portion into a second set of separate portions, each separate portion in the second set including the multifidus dorsi, complexus, and longissimus dorsi muscles.
