Protect your pigs from Mycoplasmal Pneumonia
Mycoplasmal Pneumonia remains one of the most persistent respiratory challenges in modern pig production. Causing reduced growth, poor feed efficiency and increased antibiotic use, it quietly erodes farm profitability. Early action and strict prevention are the only ways to stay in control.

What causes Mycoplasmal Pneumonia?
Mycoplasmal Pneumonia is caused by Mycoplasma hyopneumoniae, a microorganism that attaches itself to the surface of the respiratory tract, particularly to the cilia lining the airways. These cilia normally help to clear inhaled particles and pathogens, but once colonized by Mycoplasma, their function is severely compromised.
The damage disrupts the natural defense system of the lungs, allowing secondary pathogens to invade more easily. The infection progresses slowly and often becomes chronic, with long-term effects on the animal's health and productivity. Although it rarely causes sudden death, its impact on performance is significant and persistent.
How does it spread?
The primary mode of transmission is through airborne droplets expelled during coughing or close contact between pigs. Infected animals, including those not yet showing symptoms, can release the Mycroplasma into the air, contaminating pens, tools, and even personnel clothing.
The spread is most efficient in environments with high stocking density, poor air circulation, and inadequate hygiene practices. Cross-contamination between age groups or production phases—especially when biosecurity protocols are weak—amplifies the speed and reach of the infection.
Seasonal stressors like cold weather or sudden climate changes can further aggravate transmission, as pigs become more susceptible to respiratory distress.

Main symptoms to watch for
Symptoms of Mycoplasmal Pneumonia vary in severity:

- Uneven weight gain in the group
- Frequent dry coughing, especially after movement
- Increased respiratory effort or labored breathing
- Reduced growth performance
- Secondary infections

How to stay protected
Reducing the impact of Mycoplasmal Pneumonia requires a proactive strategy focused on hygiene, air quality, and consistent herd management. The infection itself may be slow-moving, but its consequences—chronic cough, uneven growth, and increased susceptibility to co-infections—can undermine herd performance across the board.
A cornerstone of protection is maintaining strict biosecurity and thorough sanitation routines between groups. One key solution is the use of proven products such as MS Megades Novo. This powerful broad-spectrum disinfectant is proven to eliminate many harmful bacteria, helping you ower the infection pressure and give the next group of pigs a cleaner, safer start.
The 5 steps to prevent Mycoplasmal Pneumonia

Optimize air quality and ventilation
Poor air circulation leads to high humidity and accumulation of harmful gases like ammonia, which irritate the respiratory tract and weaken the pigs’ natural defenses. Ensure a consistent airflow throughout the building and adjust ventilation to match external weather conditions and pig density.:format(webp))
Separate age groups and follow all-in/all-out management
Mixing pigs of different ages increases the risk of disease transmission. Strict separation and moving pigs in complete groups—without returning or introducing new individuals—limits contact between infected and naïve animals, disrupting the infection chain.:format(webp))
Vaccination, nutrition and stress reduction
A strong immune system starts with vaccination, balanced feed and low-stress conditions. Consult your veterinarian to create an appropriate vaccination plan for your pigs. Ensure that pigs have access to fresh, quality feed and clean water. Minimize stressors such as overcrowding, temperature fluctuations, and abrupt handling, especially around weaning.:format(webp))
Monitor herd health and act quickly on early signs
Regular observation of coughing patterns, growth rates, and feed conversion can help detect early symptoms of respiratory issues. At the first signs, isolate affected animals and consult your veterinarian to adjust vaccination protocols or implement supportive treatments.Frequently asked questions about Mycoplasmal Pneumonia
