Coopworths in The US
The first Coopworths were imported into the US in the 1970s by Jonathan May of Virginia and Don Gnos of Oregon. In 1980, Woodsedge Wools of New Jersey imported 10 bred ewes, and in the early 1980s, OSU in Oregon imported Coopworth ewes which had been implanted with Booroola Merino embryos. Other Coopworth sheep importers were Jan and Trudy Van Stralen of Canada, and Don Wilkinson, Oregon Extension Specialist. Artificial Insemination (AI) has replaced importation of sheep because of the expense of quarantine requirements.
