The Cornell University Sheep Program developed and teaches the STAR system to promote frequent lambing with Dorsets. Cornell maintains a research and teaching flock five miles south of Dryden, New York, USA. The Dorset has a white face with close short fleece. It has a solid build, with broad back and short legs. Originally, both rams and ewes had horns. The Polled Dorset originated in a herd at North Carolina State University, Raleigh, North Carolina, and a registry of the polled Dorset was established in 1956. Since then the polled breeders have outnumbered the breeders of the horned variety.
