Barley samples from Allamakee County were used in a swine feeding study. Pigs fed a barley-corn and soybean meal (SBM) diets containing up to 0.18% ergot (1.62 ppm ergot alkaloids) performed similarly to pigs fed a basal corn-SBM diet. In general, the level of ergot contamination in the final diets was insufficient to depress the performance of growing and finishing pigs.
