In Merino wethers, increasing the intake of cystine-S or inorganic SO,-S under steady state feeding conditions significantly increased ruminal sulphide concentrations and decreased the flow of soluble copper to the omasum. The curvilinear regression of soluble Cu outflow (y, mg/day) on ruminal S= levels (x, ,ug-ml) was y = 5.57 -2.36x+ 0.491x20.0333~3 (r = 0.95; P<O.OOl), but the flow of soluble Cu was not significantly correlated with the flow of protein from t h e rumen (r = 0.48).
