Some cattlemen take advantage of heterosis (hybrid vigor), with crossbreeding or composites. Research in the early 1900’s demonstrated the benefits, including breed complementation (combining desired traits from 2 or more breeds, to gain characteristics lacking in one of the parent breeds).
By careful crossbreeding you can add traits from a different breed, and overcome some of the weaknesses of each breed. The crossbred animal also benefits from heterosis—the performance advantage that enables the crossbred to exceed expectations of the parent breeds.
