Managing the Disease


Prevention is very dependent on good management that provides an optimal environment for the pigs and thus decreasing pig susceptibility to Mycoplasma hyopneumoniae (M. hyo). Attention to air quality, ventilation, temperature, stocking density, age segregation and a strict all-in all-out policy are very important in preventing the spread of this pathogen between pigs. In addition, segregated early weaning, multi-site production operations and closing of the herd can further help to eliminate this pathogen.


Antibiotics are effective in the treatment and prevention of M. hyo infections, but timing can be challenging. Treating too late or too early is ineffective, so it often needs to be continued over an extended period. Medicated Early Weaning can produce litters free of M. hyo.


Vaccination of piglets with Porcilis PCV M Hyo, Porcilis M Hyo, M+PAC or Porcilis M Hyo ID ONCE before the infection occurs can be an efficient strategy for preventing damage from M. hyo infections.
