Abstract
Using respiration calorimetry and carbon-nitrogen balance studies, the efficiency of utilization of metabolizable energy for maintenance and production has been determined on eland and wildebeest. These results are compared with those which might be anticipa· ted if cattle or sheep were fed on similar rations. The eland and wildebeest used in these experiments had a fasting metabolism greater than the interspecific mean of about 70 kcal per kg metabolic body weight. They utilized the corrected metabolizable energy for maintenance purposes with an efficiency of more than 80 %. a figure comparable to that found for cattle and sheep. and were generally slightly more efficient in using metabolizable energy for production. The carbon-nitrogen balance data indicated that when rations high in available carbohydrate and protein were fed. the principle storage product was body fat.
