Lincomycin-medicated feed for the control of porcine proliferative enteropathy (ileitis) in swine

Results: The L intracellularis challenge produced a high incidence of clinical disease. The incidence of diarrhea and scores for abnormal clinical impression were lower and ADG and feed conversion efficiency were better in groups treated with either dose of lincomycin than in untreated controls. Mortality was lower in the group treated with lincomycin at 110 ppm than in the untreated controls. Implications: Under the conditions of this study, lincomycin administered in feed at 44 and 110 ppm for 21 consecutive days was effective in controlling clinical signs of PPE, and at 110 ppm also reduced mortality associated with PPE.
