7 Pa. Code § 101.1
The following words and terms, when used in this chapter, have the following meanings, unless the context clearly indicates otherwise:
Conformation-The general body portions of a bovine animal and the ratio of meat to bone. Conformation is determined primarily by the inherent muscular and skeletal system, but is also influenced by degree of fatness.
Finish-The fatness of a bovine animal. The quality, quantity and distribution of finish are closely associated with the palatability and quality of the meat.
Quality-The refinement of hair, hide and bone to the smoothness and symmetry of the body of a slaughter calf or vealer. Also related to the carcass yield and proportion of meat to bone.
Slaughter calf-Young bovine animal usually between 3 and 8 months of age which is subsisted partially or entirely on feeds other than milk for a substantial period of time. The middle is heavier than that of a vealer and the calf has the overall physical characteristics associated with maturity beyond the vealer stage.
Vealer-Young bovine animal typically less than 3 months of age which subsisted largely on milk and has the characteristic trimness of the middle associated with limited paunch development.
