The Dorper is a hardy South African composite breed, derived from a cross between the Black-headed Persian and the Dorset Horn. Dorpers are regarded as early-maturing, and ewes lambed at an age of 1 year in one study. Age at first lambing was higher in other literature sources cited. The fertilit...

Live mass reproduction and pelvic dimensions (determined mainly by radiographic pelvimetry at more than 4 years of age) were obtained for ewes of the Langgewens Merino flock (n=102), ewes of the Tygerhoek Merino flock (n=434) and ewes of the Elsenburg South African Mutton Merino (n=130) and Dorme...

Plain (OAT), 1.4% urea-enriched (EOAT) and 3% themal-ammoniated (NH3OAT) oat grain were fed to South African Mutton Merino ewes as supplementary feed during late pregnancy and lactation, while grazing wheat stubble at 2 ewes/ha during 1986 and 1987. Blood glucose, urea, calcium, magnesium and zin...

This study was undertaken to investigate the genetic stability of an unselected Conlrol Group of South African Merino sheep and genetic change in a flock selected for increased clean fleece mass (Selection Group) under the same environmental conditions. Data regarding 14-17 months clean fleece ma...
