It is probable that the ancestral stock of the Red Sindhi was a principal component of the Zebu cattle brought from medieval India to Sudan over a thousand years ago to form the basis of the Butana breed, but that they are so identical after all this time is very surprising. The Kenana cattle are probably derived from the Butana, they are the same deep red as calves, but turn white when they are adults.
The Red Sindhi's ancestry is likely tied to a crucial component of the Zebu cattle brought to Sudan over 1,000 years ago, which eventually gave rise to the Butana breed. The astonishing similarity between these breeds despite such a long history is noteworthy. The Kenana cattle are believed to have originated from the Butana, retaining their distinctive reddish hue in calves that gradually fades to white as they mature.
