From a game farming point of view, the impala is quantitatively the most important animal in the Bushveld areas of South Africa. However very little published data are available on the productive capacity of this animal. In a long-term study of the impala in the Kruger National Park, certain production parameters have become available that can be used to evaluate the game farming potential of this animal. Mean life-expectancy at birth is 2,6 years under natural conditions, with 64 per cent of those born entering the second year of life, but only 12 percent entering the sixth year. The sex ratio at birth is equal but at maturity it is skewed toward the female segment viz. 65 per cent. Reproduction is very strictly seasonal, with a mean conception date on 10th May and a standard deviation of ± 22 days. The ewe has a maximum of two cycles in this period, but usually conceives at the first oestrus. Fecundity is 90-95 per cent in mature females, but lower in two-year-old ewes and is influenced by climate. No sign of reproductive senility has been found in animals of up to 12 years. Growth is rapid and asymptotic mass is achieved at 5 years. Dressed mass, is 53 per cent of warm carcass mass, at 9 months and 57 per cent at 24 months and older. The better cuts make up a large proportion of the impala carcass and the meat is lean, having almost no visible fat.
