Factors Associated with ELISA Sample/Positive Ratio Scores for Paratuberculosis in an Angus-Brahman Multibreed Herd of Beef Cattle

摘要

Paratuberculosis is a chronic disease of ruminants that causes economic losses in beef and dairy cattle due to diminished production and eventually death. Dam and calf genetic and environmental factors were evaluated for their association with enzyme-linked immunosorbent assay (ELISA) sample to positive ratio scores for paratuberculosis in a multibreed beef cattle population.
