Muscling in swine is evaluated by how much muscle development the pig shows, described with simple qualitative terms. The standard descriptors are thick, average, and thin. Thick indicates a heavily muscled pig with more noticeable muscle depth, which usually signals higher yield potential. Average represents typical muscling, while thin reflects less muscular development. These terms are used because they convey relative muscularity quickly and consistently for comparison, selection, and carcass yield planning.

Other word choices don’t fit as well because they describe different attributes. Heavy/medium/light tends to imply overall size or density rather than the specific degree of muscular development. Large/medium/small emphasize size more than muscle quantity. Strong/moderate/weak refer to structural strength or overall power, not the amount of muscle tissue.
