Scottish highlands are unique among the many other mainstream breeds, such as Black Angus, Simmental, and Hereford. They are known mainly for their long, wavy hair; horns; short stocky structure; and longevity. In addition to these, highlands have a reputation for producing some of the leanest and most flavorful beef on the market. Because of highlands' genetic diversity, they are becoming a popular breed for crossbreeding. When crossed with a Shorthorn for instance, they create a calf that displays hybrid vigor. Hybrid vigor means that their terminal calves will finish at a younger age on less feed and have a higher yield at slaughter.
