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), Viljoenskroon, Welkom, (Ferdie
Naude), Clocolan (Marloo), Steynsrus (Viljee Crous) and Hekpoort (Sanders).
The ARC-Animal Improvement Institute and SA Stud Book and

administration of the Integrated Registration and Genetic Information System (INTERGIS).
