Abstract Original imports of Black Pied cattle were of various types and productive potential and could hardly be called Friesians. South African Frieslands contain blood from Afrikaner, Bechuana and Damara cattle and so are very heterogeneous. Uncontrolled breeding with native and with several imported breeds continued until about 1905, resulting in total degeneration of some outstanding native breeds. After 1905, with the foundation of a herd association this haphazard crossing slowly decreased. The register played an important part but was of no scientific merit and required reorganisation. Many Friesland herds in South Africa are very heterogeneous, both phenotypically and genotypically. Outstanding Friesland herds were always linebred and originated mainly from Jan 3265 FRS, Ceres 4497 FRS and Albert 1306H FRS. The openness of the register permitted registration of grades and ought to be abandoned. A few uniform herds of Frieslands were already available in South Africa. The new registration system of 1933 was more national, requiring a basic conformation and production score. But the scoring system ought to be revised to emphasize general features of conformation rather than figures. The 'Preferent Sire' award should be supplied only after a very thorough test of all progeny.
