Evaluation of the Recrudescence of Actinobacillus pleuropneumonia in Growing Pigs Following Pulmotil Treatments in Nursery and Grower
Purdue University 1999 Swine Research Report. Pulmotil is effective at preventing clinical outbreaks of respiratory disease caused by Actinobacillus pleuropneumoniae (App) and Pasteurella multocida (Pm) when fed at 200-400 ppm. Dose determination studies with Pulmotil indicated that App could not be isolated from lungs of pigs following a 21-day treatment with 300 or 400 ppm Pulmotil. Studies examining the recrudescence of clinical disease in pigs following Pulmotil treatment have not been performed. We investigated the potential for recrudescence of App following Pulmotil treatment at 400 ppm in nursery or growing pigs.
