Disease Management via ID Vaccination
The MSD Animal Health Porcilis® intradermal vaccine range can protect against common diseases caused by:
- Porcine Circovirus Type 2 (PCV2)
- Mesomycoplasma hyopneumoniae (M. hyo)
- Lawsonia intracellularis (Lawsonia)
- Porcine Reproductive & Respiratory Syndrome (PRRS)
As we launch our newest member of the IDAL™ vaccine family, let’s take a deep dive into PCV2 and M. hyo.
Porcine Circovirus Type 2 (PCV2) and Mesomycoplasma hyopneumoniae (M. hyo)
Porcine Circovirus Type 2 (PCV2) and Mesomycoplasma hyopneumoniae (M. hyo) are infectious agents causing two of the top five diseases impacting swine production.
M. hyo is the primary initiator of Enzootic Pneumonia (EP), a chronic respiratory disease which can be associated with:
A dry and non-productive cough
High morbidity rates
A negative effect on average daily gain and feed conversion ratio
Amplification of the severity of other infections, including flu, PRRS and PCV2
A dry and non-productive cough
A high morbidity rate
A strong effect on the average daily gain and feed conversion ratio
Amplification of the severity of other infections, including flu, PRRS and PCV2
PCV2 causes porcine circovirosis. Clinically, it presents as a disease which causes wasting from the weaning to the finishing period. Characteristics include:
- Immunosuppression
- Strong environmental resistance
- Potential for high mortality
Concurrent infection with PCV2 and M. hyo causes:
- Severe respiratory disease
- Lesions consistent with Porcine Respiratory Disease Complex (PRDC)
Economic impact of disease
PCV2 has an enormous impact on productivity, with mortality ranging from 4% to 20%. Before implementation of preventive measures, the cost of the disease for the EU was estimated to be between €562 and €900 million per year.1
Economic losses associated with PCV2 and M. hyo are a consequence of:
- Increased mortality and culls
- Reduced growth rates with an overall worsening of production parameters (ADWG, FCR)
- Increased cost for management and medication of sick pigs
- Increased costs as a result of secondary diseases
