Heat tolerance in West African cattle
1971
Kahoun, J., Animal research Institute, Council for Scientific and Industrial research
West African cattle (West African Shorthorn and N'Dama) continuously exposed to direct sunlight (85°F and above air temperature in the shade) for 10 days showed evidence of substantial compensation to a stabilized state in body temperature.However, a gradual decline occurred in body temperature during the experimental period. Generally, after 5 days of exposure, the experimental animals made compensatory adjustments and their body temperature became stabilized to the environmental temperature. It is evident that West African cattle can adapt to direct sunlight at constant environmental temperature of as high as 90°F. Further investigation is needed to enable a comparison to be made between physiological responses of local cattle and imported temperate-climate cattle and their crossbreds.
