The Ankole-Watusi is a modern American breed of domestic cattle.

It derives from the Ankole group of Sanga cattle breeds of east and central Africa.

[4] In 2016 the total number for the breed was thought to be approximately 1500 head, some 80% of them in the United States.

The horns are unusually large, with a wide spread[2]: 110  and the largest circumference found in any cattle breed.

Guinness World Records lists a bull named CT Woodie with a horn circumference of 103.5 cm (40.7 in) and a steer named Lurch, with horns measuring 95.25 cm (37.50 in), as record-holders.
