4 Pillars of PRRS Control

1. Diagnostics

• Determine where PRRS is causing a problem in the herd

• Sample types: blood, saliva or fresh body tissue

2. Herd management

• PRRS control relies on achieving stable PRRS immunity in the breeding herd

• Stability often pivots around gilt management

• Ensure gilts are properly vaccinated and acclimatised

3. Vaccination

• Vaccination using a live PRRS vaccine can control clinical signs and reduce shedding of PRRS virus

4. Biosecurity

• Biosecurity is key to preventing:

- PRRS entering a negative herd

- New strains entering a PRRS positive herd

- PRRS spreading within the herd
