Backbone is transversely severed between the 3 rd and 4 th dorsal vertebrae and at the level of the cervical/dorsal joint, separating the neck this way. Then a cut is made parallel to the backbone from the caudal edge of the 3rd rib up to the 1st rib of the cranial edge, at an approximate distance of 50 to 75 mm from the ribeye lateral end. Having obtained the bone in cut, deboning operations are carried out and remaining portions of some muscles, such as m. Intercostalis and m. Levatores costarum, are removed. M. Subscapularis may be retained or removed.

The 1st, 2 ndand 3 rddorsal vertebrae and corresponding spinal rib ends, blade bone and scapular cartilage.

M. Rhomboideus, m. Complexus, m. Splenius, m. Longissimus dorsi, m. Spinalis dorsi, m. Multifidi dorsi, m. Iliocostalis, m. Serratus dorsalis cranialis and m. Subscapularis.
