Upgrade Program

Grading up is not a new concept. It has been used for years in many species. We are probably most familiar with its recent use in establishing flocks of foreign breeds in this country, as with the Wensleydale and Gotland sheep breeds.

Through upgrading, we can increase the population of the breed quite rapidly while introducing genetic diversity and vigor. We must, however, take into account the character and purpose of the Coopworth when we upgrade. The most benefit will be made if the newly introduced genes are similar to those in the current gene pool. By maintaining a reasonable degree of predictability within the breed, we preserve its integrity.

Animals from the following breeds, and crosses of them, may be used for the foundation of upgrading in this program:
:

Coopworth Corriedale Cotswold All Leicester types * Lincoln Perendale Romney

* Due to the small population of Leicester Longwools in the U.S., the ACR discourages their use for upgrading.

The animals you begin with, known as foundation animals, should meet the standard for their particular breeds and crossbred animals should exhibit the best qualities of their breeds.

During the upgrading process, it is especially important to select for qualities that are typically Coopworth, choosing and retaining only those animals that show the greatest potential. The resulting upgraded animals must look and behave like Coopworths. The Coopworth Breed Standard and Culling Guidelines (ACR By-laws Art. XII) are helpful tools along with your personal flock records.
