Which breed is most likely to excel in muscularity?

Meat or terminal sire breeds are specifically developed for their ability to produce high-quality meat, which is characterized by muscularity. Breeds in this category, such as Suffolk and Hampshire, have been selectively bred to emphasize muscle growth and lean carcass development. This focus on muscularity means that they typically have a well-defined muscle structure, contributing to higher meat yield and better marketability in the meat industry.

Fine wool, long wool, and dairy breeds are primarily bred for their fiber or milk production, rather than for their muscular characteristics. Fine wool breeds are valued for their soft, fine fleece; long wool breeds are recognized for their long wool fibers; and dairy breeds are optimized for milk yield and quality. While these breeds may possess some degree of muscle, it is not their primary trait or the focus of their breeding programs.
