[The composition of Merino flocks in the Republic of South Africa (author's transl)].
The various sex and age components of Merino sheep flocks are analzed. Since a similar survey in 1965 the most significant difference is an increase from 40 to 52% of the mature female component. Various indicators point to an inability of the farmer to influence this slow rate of increase. The significant role which the prolonged retention of young Merino whethers on the farm plays in this respect is discussed. A higher percentage of rams during the mating period is also suggested.
