Joan Burke is a Research Animal Scientist with USDA, ARS since 1999. She received a B.S. in Animal Science from Cornell University and Ph.D. from Oregon State University. Dr. Burke conducts research on sheep, goats, and cattle, focusing on providing technology to enable small to mid-size farmers to maximize profits. She has published as author or co-author research articles on the validation of the FAMACHA© system in the U.S., use of copper oxide wire particles to control Haemonchus contortus, feeding sericea lespedeza to aid in the control of gastrointestinal nematodes, using rotational grazing to minimize the need for deworming lambs, animal selection for parasite resistance, and effects of endophyte-infected tall fescue on production and reproduction in sheep and cattle. Dr. Burke has been able to conduct this research through funding by USDA, ARS, USDA, OREI, Southern Region SARE, and USDA, SBIR.
