The National Beef Cattle Improvement Scheme is managed by the Animal Production Institute (API) of the Agricultural Research Council (ARC), who is responsible for the technical control and supervision of the Scheme.
There are ten central bull testing centres in the beef cattle areas of South Africa), with a total capacity for testing 5 000+ bulls per annum. Four of these centres are ARC-owned, namely at Pretoria (Irene), Vryburg (Armoedsvlakte), Bloemfontein (Glen), and Pietermaritzburg (Cedara) and six privately-owned, namely at Edenville (Sernick), Clocolan (Marloo) and Hekpoort (Sanders), Waterford (Klerksdorp), Dhofstee (Heidelberg), Bufland (Mookgopong) and Winter Castles (Port Elizabeth).
The ARC-Animal Improvement Institute is co-responsible for the management and administration of the
Integrated Registration and Genetic Information System (INTERGIS).
