The Aberdeen Angus, sometimes simply Angus, is a Scottish breed of small beef cattle. It derives from cattle native to the counties of Aberdeenshire and Angus in north-eastern Scotland. The Angus is naturally polled and solid black or red, though the udder may be white. The native colour is black, but more recently red colours have emerged. The UK registers both in the same herd book, but in the US they are regarded as two separate breeds – Red Angus and Black Angus. Black Angus is the most common breed of beef cattle in the US, with 332,421 animals registered in 2017. In 2014, the British Cattle Movement Service named Angus the UK's most popular native beef breed, and the second most popular beef breed overall (Wikipedia).
