Ewes and lambs grazing spring pastures at the Southwest AREC as part of a pre-weaning study of genetic resistance levels to internal parasites.

Internal parasites are the primary production challenge for sheep producers in Virginia and the surrounding region. Genetic selection for parasite resistance is becoming a critical control mechanism, as other strategies have become less effective. Therefore, properly designed and implemented genetic evaluation protocols for parasite resistance are needed.

In response to these needs, a forage-based ram evaluation program, the first to be conducted nationally, was initiated at the Southwest AREC in 2012. Interest in the program has attracted over 1,000 rams from collaborating producers, representing flocks from 16 states (VA, AR, FL, GA, IN, KY, MD, MO, NC, OH, PA, SC, TN, TX, WI, WV). Rams from these flocks are evaluated over the grazing season for growth performance and parasite resistance, applying protocols based on previous research conducted at the center. At the conclusion of each test, an educational field day is hosted, and top performing rams offered for sale to the public.

The program has successfully demonstrated methods for collection of on-farm data necessary to select for the economically relevant traits of growth and parasite resistance. Sources of variation in parasite resistance have continued to be documented, and serve as benchmarks for on-farm application by producers, and for inclusion into national genetic evaluation programs for the sheep industry. A subset of 343 tested rams have sold at auction, averaging $1,336 per ram and gone to 17 states. Estimated value-added per ram was $750 over typical market value. Results have been shared through Extension publications, popular press, and to the scientific community.

“Forages are a key component to all livestock operations in Southwest Virginia, and our climate allows cool season forages to thrive. Area VCE agents work closely with SWAREC to conduct numerous variety and fertilization trials, to assist producers with management decisions to maximize quantity and quality of forages to maintain profitable family farming operations.”

“By any measure, the Ram Test Field Day & Auction is an absolute success, and of great value to sheep producers in the region. Our flock has benefited greatly from the genetics purchased through this program. Thank you for your vision and many years of hard work. We cannot say enough positive things about this annual event.”

About the Southwest Virginia AREC

The Southwest Virginia AREC was established in Glade Spring, Virginia in 1947 and primarily serves the commonwealth through forage-based, livestock production systems research. Corn trials, pine tree plantings, and various specialty crops are also produced. The AREC conducts field days and tours for producers and the general public to introduce people of all ages to our programs and to the world of agriculture in Southwest Virginia.

A collaborative Network

The ARECs are a network of 11 centers strategically located throughout the state that emphasize close working relationships between Virginia Agricultural Experiment Station, Virginia Cooperative Extension, and the industries they work with. The mission of the system is to engage in innovative, leading-edge research to discover new scientific knowledge and create and disseminate science-based applications that ensure the wise use of agricultural, natural, and community resources while enhancing quality of life.
