They reach maturity slower than meat breeds as they were not selected to be heavy, having instead a well-muscled "athletic" look, with a prominent morrillo, a complex of muscles over the shoulder and neck which gives the bull its distinctive profile and strength with its horns.
The description highlights the slower maturation rate of these animals compared to meat breeds due to their selective breeding for muscularity rather than size. The "athletic" appearance is emphasized, as well as the prominent morrillo, a key feature contributing to the bull's strength and distinctive profile.
