Which breed is primarily known for its beef production and solid black color?

The breed primarily known for its beef production and solid black color is Angus. This breed is highly regarded in the beef industry due to its ability to produce high-quality meat with marbling, which enhances flavor and tenderness. Angus cattle are also known for their solid black color, although there are red Angus as well, the classic image associated with Angus beef is the black coloration.

In addition to their color and meat quality, Angus cattle have a reputation for being easy to handle and adaptable to various environments, which makes them a popular choice among beef producers.
