    Origin of the breed When J.J.J. Kotze was appointed first Director of the newly established Dohne Agricultural Research Station near Stutterheim, he soon realised that the harsh sourveld environment at Dohne required a better-adapted and more efficient sheep type. He commenced breeding trials in 1939 and it soon became evident that crosses between the local Merino and SA Mutton Merino were well adapted and highly productive in the sour grassland regions around Dohne. A program was launched to fix the excellent characteristics of the first cross and, through inter-breeding and selection, to develop a dual-purpose fine-woolled Merino-type capable of high levels of lamb and meat production in the environment. By the 1950s a clear type had emerged and the new breed was becoming established commercially. By 1966 the number of breeders

    had increased to such an extent that a breed society was established. Description A medium to large framed white woolled polled breed. Rams and ewes are polled. Face should be free of kemp, covered with soft cream-coloured hair. No jowel pleats are allowed. The Dohne Merino produces white wool with a soft handle, well defined, even crimp and no kemp or hairy fibres. No coloured fibres are allowed.

    Products

    Meat - Lambs do not accumulate fat at an early age and can therefore be marketed at a later age and higher body weight.

    Wool - Dohne Merino wool is the closest to the Duerden standard with regard to crimp frequency of all South African wools.

    Normal production environment The majority of the Dohne Merino sheep in South Africa are farmed with in the Eastern Cape, Free State and Western Cape provinces. Breed numbers There are currently 31 000 Dohne Merino ewes registered with the Dohne Merino Breeders Society. The total number of Dohne Merino sheep in South Africa is unknown.
