Summary and Implications
Condensed corn distillers solubles fed over an extended period may have some impact on liver tissue copper concentration due to the high sulfur content of this feedstuff. However, if the total ration concentration of sulfur is maintained below 0.30 percent of the diet as dry matter intake there does not seem to be any adverse effect in steers in terms of causing brain lesions.
