A genetic control flock of Merino sheep consisting of 160 ewes and 16 rams was established in 1969 at the Tygerhoek Experimental Farm near Riviersonderend in the South Western Districts of South Africa. In 1976 it was extended to 200 ewes and 20 rams. Ewes are replaced by their second ewe lamb when...
