Results of this study suggest that carbadox was incorporated uniformly in the feed by mixing. However, the two medicated feed additives containing sulfamethazine did not incorporate uniformly in the feed. The causal mechanism for the poor mixing performance of sulfamethazine was not discovered; however, assay variability was eliminated as a primary source of variation. Flushing the feed mixing, conveying, and sack-off systems twice with ground corn did not eliminate drug carryover. Further investigation of the mixing and clean-out properties of medicated feed additives is warranted.; Swine Day, Manhattan, KS, November 16, 1995
