  1. athe average age of the pigs at arrival was 26 days, ball pigs of the NCG and DON group, and five pigs of MHYO were necropsied at D35. Ten pigs of MHYO and all pigs of DONMHYO were necropsied at D36, cRDS was not determined at D0 and D36 because the piglets arrived later than 8 a.m. (hour of performing coughing score every day) and part of the piglets were already euthanized on D36, respectively, dsham-inoculation was performed with sterile Friis medium, ehighly virulent strain of M. hyopneumoniae, flow virulent strain of M. hyopneumoniae
