AVOIDING SEROLOGICAL AND CLINICAL PROBLEMS CAUSED BY ACTINOBACILLUS PLEUROPNEUMONIA AND MYCOPLASMA HYOPNEUMONIA IN COMMINGLED WEANER PIGS BY TILMICOSIN TREATMENT

摘要

It has been demonstrated in a seeder pig model that a 21-day course of treatment with tilmicosin (Pulmotil Premix, Elanco Animal Health) started 7 days before infection can prevent colonisation of the lung with Actinobacillus pleuropneumonia (App.). This paper is a description of a trial to investigate the effect of tilmicosin medicated for 15 days with 400 mg/kg feed on the clinical signs and sero-conversion to App and Mycoplasma hypneumonia (Mh) in commingled weaner pigs from sources with different health status.
