Coke's hartebeest (Alcelaphus buselaphus cokii) or Kongoni is a large migratory antelope that is native to Kenya and Tanzania.

The hot and dry environment of the Coke’s hartebeest has led to the development of several thermoregulatory adaptations.

Most desert animals maintain a lower metabolic rate in keeping with the low nutrient availability within their environments.

For hartebeest, the metabolic response during the fasted state (when food has been digested and stored) leads to adaptations that aid in protein conservation.

[4] This helps the Coke’s hartebeest limit its water expenditure in hot and arid habitats.
