Impacting Health of Meat Goats and Sheep in Appalachia
Among the most significant constraints on small ruminant enterprises are diminished production and animal death attributable to gastrointestinal parasite infections. The principal culprit is Haemonchus contortus (barber pole worm), a species that has developed resistance to every class of pharmaceutical dewormers. Because no new anthelmintic drugs for small ruminants are being developed, integrated parasite control strategies are crucial for sustainability of meat goat and sheep production. Bioactive plants that can disrupt the parasite life cycle are considered essential components of this integrated approach, especially for small farms with limited management alternatives. Our goal is to discover regionally adapted plants that can meet nutritional and health needs of small ruminants produced in the humid, temperate conditions of Appalachia. We also develop management practices for these plant species. Emphasis is on plant characteristics that adversely affect free-living stages of the parasite in pastures and on phytochemicals that are effective against parasitic stages in animals. We investigate the antioxidant capacity of forage species to define plant resources that can improve immune system function of small ruminants, in response to gastrointestinal parasite infection. Our research uses a systematic approach combining laboratory and field experimentation techniques to discover bioactive plants and plant compounds that are safe for use by grazing livestock.
