PROTEIN INTAKE AND WATER TURNOVER: A COMPARISON OF TWO EQUIVALENTLY SIZED AFRICAN ANTELOPE THE BLESBOK Damaliscus dorcas AND IMPALA Aepyceros melampus

Water turnover in blesbok and impala was studied in the field. Water turnover of the impala was double that of blesbok, this difference was related to crude protein values in the diet. These facts are related to the evolutionary adaptations of the species. Key words: Water turnover, protein intake, impala, blesbok
