Sheep and goats have been kept by Bantu-speaking farmers since their arrival during the Early Iron Age in southern Africa. Published samples dating from the Early, Middle and Late Iron Ages are used in this paper to investigate the exploitation of these two domestic animals. A Caprine Index is introduced to measure the ratio of sheep and goats in samples. In almost all cases, samples from the entire Iron Age are dominated by sheep, although the representation of goats increases slightly towards the Middle and Late Iron Age. Three exceptions to the pattern exist in the region, namely Mapungubwe Hill (Middle Iron Age), Nyanga and Hill X (Late Iron Age). At Mapungubwe Hill, the possibility exist that the dominance of goats over sheep is a factor of identification limitations when the original study was conducted in the late 1970s. However, a study is currently underway to re-analyse the fauna from this site. By the middle of the 20th century, goats are more common than sheep under Bantu-speaking farmers in South Africa, a pattern that may be attributed to social, economic, political and/or environmental changes.
