International flocks

The majority of Sheep Genetics members are Australian flocks, however, international members submit data to the Sheep Genetics evaluation from New Zealand, South America, and Asia. Table X displays the number of flocks by country. Such international flocks use Australian genetics and are therefore linked and their genetic merit is directly comparable to Australian flocks in the Sheep Genetics evaluation. Sheep Genetics also has X clients in the United States of America within the National Sheep Improvement Program (NSIP) which receive Estimated Breeding Values (EBVs).
