Bororo cattle...

...in my opinion the most beautiful cattle in the Sahel. The Bororo are bred by the Wodaabe, a sub-group of the Fulani.

'The Bororo cow is characterized by a special attachment to its owner, being extremely obeying and responding well to commands given by people, in addition to knowing their names. They get used to specific people handling them, refusing cooperating with strangers, such as in terms of milking and watering. WoDaaBe sees this attachment to the owner as serving practical purposes because, as they frequently emphasize, it is almost impossible to steal a Bororo cow. They run away from a stranger, refusing cooperation. The Bororo cows are also characterized as fiercely independent and can in some situations be dangerous to people. Dupire points out that they can merely be seen as partly domesticated animals, referring to their characteristic as "semi-sauvage" (Dupire 1962: 95). WoDaaBe describe Bororo cattle as having djikku (character), which is the same term as used in relation to people. To have djikku is usually characterized negatively by WoDaaBe in relation to people, then as referring to loss of self-control, but the use of such a term in relation to cows can be seen as placing them on the same level as people, conceptualizing them as animals with temper and independent personalities.'
