Comparison of treatment methods for the control of contagious ovine foot rot.
Four methods of treatment for ovine foot rot were evaluated: foot trimming and topical treatment (brief, daily foot bathing in 10% zinc sulfate); vaccination with an oil-alum adjuvanted, multivalent, Bacteroides nodosus bacterin, vaccination with the bacterin plus foot trimming and brief foot bathing, and 1-hour 10% zinc sulfate foot soaks. Compared with results of sheep in a nontreated control group, vaccination reduced the number of infected feet by 8%. Daily walk-through foot bathing reduced the number of infected feet by 16%, and vaccination and foot bathing reduced the number by 27%. In another experiment, treated but nonresponsive sheep were subjected to 2 one-hour foot soaks in 10% zinc sulfate. Compared with results in nontreated controls, the soaks reduced the number of affected sheep by 58%. Previously nontreated sheep responded with a 69% reduction of affected animals over controls.
