Efficacy of In-Feed Valnemulin Hydrochloride for the Treatment and Control of Ileitis in Weaning and Growing Pigs

To evaluate effect of in-feed valnemulin hydrochloride on control of proliferative enteropathy in weaning and growing pigs, 288 weaned piglets from a farm with a previous history of ileitis outbreaks were divided in three groups. The first group served as negative control, the second one received 50 ppm in-feed valnemulin hydrochloride, while the third one received 100 ppm in-feed tylosin phosphate for 21 d. Valnemulin hydrochloride and tylosin showed an effect in reducing diarrhea due to ileitis and the prevalence of Lawsonia intracellularis in faecal samples at the end of the growing period. There was also a significant improvement of productive parameters (body weight, ADG, FCR). Conclusively, the administration of valnemulin hydrochloride via feed, at the inclusion level of 50 ppm and for 21 d, controls ileitis significantly in weaned and growing piglets.
