Technical Abstract: Small ruminant production has been expanding in the upper transition zone where tall fescue (Lolium arundinaceum L.) is the dominant perennial cool-season grass forage species. Although the grass is well adapted to the region, an endophyte (Neotyphodium coenophialum) that infects most tall fescue plants produces ergot alkaloids, which can cause a toxicosis in cattle that negatively affects reproductive performance and weight gain efficiency. Little is known about the effect that ergot alkaloids have on the physiology and production of sheep and goats, but limited research suggests a negative impact of ergot alkaloids on sheep and meat goat production when endophyte-infected tall fescue is the major constituent of the diet.
