USDA standards for angus require cattle to have a solid main black body with no other color behind the shoulder, above the flanks or breaking the midline behind the shoulders, excluding the tail. Angus influence cattle may be either horned or polled.
- Blue roan, gray, etc., are not considered to be black or a percentage of black.
- Carcasses of certified live animals which display certain non-Angus characteristics (e.g.; dairy confirmation, Brahman humps) shall be excluded.
- At times, a black hair coat can become sun bleached and appear to be a shade of brown, particularly on the back. If the base of the hair close to the skin is black then the entire brown tipped area should be considered solid black. However, if the hair color is brown to the roots, it should be considered as brown in color and the area will not contribute to the solid black requirement.
