Rocklyn is a fine-medium merino and poll merino sheep stud
Situated near Greenethorpe in southwest New South Wales
Owned and managed by Ralph Diprose, Rocklyn has fine-tuned its breeding program over the decades, using the top genetics from leading bloodlines to produce plainer bodied sheep that are heavy cutting with a good early growth rate.
Sheep are bred to suit the local mixed farming environment, which has an average annual rainfall of 600mm, and to withstand climatic extremes of high rainfall or drier, dusty conditions.
Rocklyn participates in sire evaluations to benchmark the performance of its genetics.
