Boran cattle are known for their fertility, early maturation (more so than other Zebu breeds), hardiness, and docility.[4] TypesThe Orma Boran is the smallest of the Boran breeds, smaller than the Kenyan Boran. Mature male Orma Boran range in size from 225 to 395 kg, while females are from 250 to 355 kg.[5] The Kenyan Boran developed from the Orma Boran, Borana, and Somali Boran.[5] The Kenyan Boran is differentiated from other Boran due to its size and well-developed hindquarters.[5] Mature male Kenyan Boran range in size from 550 to 850 kg, while females are from 400 to 550 kg.[5] The Kenyan Boran coat colour is usually white with spots, but brown and red coat colours have also been found.[5] External links
