A swine dysentery (SD) (Treponema hyodysenteriae) model that produces consistent, homogeneous and severe SD was used in 2 experiments to compare the prophylactic effectiveness of 5 commercially available swine feed additive products. Under the conditions of these studies, carbadox and carbadox + sulfamethazine proved to be the most effective agents in preventing SD during the infection + medication and postmedication periods. Olaquindox was effective in preventing SD in the infection + medication period; SD recurrence was high during the postmedication period. Nithiamide and chlortetracycline + sulfamethazine + penicillin were least effective in preventing SD during the infection + medication and postmedication periods.
