Discover how PRRS spreads through an unvaccinated herd, and how you can stop it.
This demonstration reveals why an unprotected population faces a transmission rate of 5.4, and how a systematic whole-herd approach can dampen viral spread to a near-zero rate of 0.3. Since growing pigs make up 90-95% of a commercial herd, they act as the primary "engine of infection" where new PRRS breaks emerge.
This video illustrates how infection pressure in grow-finish barns eventually circulates back to the breeding herd, threatening the safety of your sow population.
