Genus: BosSpecies: Bos taurus
They're cattle, so Bos taurus. (Some kinds of "cattle" are actually zebu, Bos indicus, or taurus/indicus hybrids, but Angus are pure taurus.)Also, since you specifically mentioned "black" Angus: the only real difference between black and red Angus cattle is one gene for color. Black Angus have been specifically bred to eliminate the recessive gene that causes redness, and red Angus have been bred specifically FOR that gene. The original Angus breed from Scotland could be either black or red.
It is Bos primigenius taurus.
Angus cattle are classified as a breed of cattle known for their black coloration. They are originally from Scotland and are known for their marbling and high-quality beef production. Angus cattle are one of the most popular beef breeds worldwide.
Highland cattle would be Bos taurus - they have thick coats of hair, small ears, a compact body and a small dewlap. Bos indicus cattle have the opposite - thin fine coats of hair, large ears, a rangy body and a large dewlap. These adaptations are to help cool the Bos indicus cattle in subtropical climates.
Tropical cattle can be cattle from the species Bos Taurus or Bos indicus. Most cattle that live in tropical areas, however, are of the species Bos indicus.
Bos taurus cattle are typically larger in size with a rounded body shape, while Bos indicus cattle are smaller with a hump on their shoulders. Bos taurus are better suited to cooler climates and have a higher tolerance for cold weather, while Bos indicus are more adapted to hot and humid environments. Additionally, Bos indicus cattle have a higher resistance to diseases and parasites compared to Bos taurus.
The scientific name of humped cattle is Bos taurus indicus.
Bos taurus is a species name for all cattle around the world that do not have the floppy ears, the rump and loose, heat and insect-resistant skin like that of the Bos indicusspecies. Bos taurus comprises of cattle that are collectively and commonly called "European" cattle, and come from more temperate zones (cool and dry or moist), rather than the tropical areas where Bos indicus cattle come from.
Bos taurus cattle are best suited in temperate to cool climates, typical of such countries as Europe and North America. However, Bos taurus cattle are also found in tropical, arid and sub-arid countries/continents, such as Africa, Australia, and South America.
If you are referring to a dairy cow the genus is "Bos" and the species is "B. Taurus". Cows and bulls as seen on farms and ranches are referred to as "cattle".
Bos indicus and Bos taurus are two very closely related species of cattle. Bos indicus are the "tropical cattle" - they have a pronounced hump over their shoulders, a pendulous penis and prepuce (in the males), very large ears and well-developed dewlaps (redundant skin over their briskets or chests). Bos taurus are the "temperate cattle" - they have smaller ears, carry the penis close to the body, no hump and very little redundant skin. Bos taurus is the species of cattle that Angus, Hereford and Piedmontese fall under.
