Science page: Measuring production losses from endemic PRRS in US farms

This is our new Friday rubric: every week a new Science Page from the Swine Health Monitoring Project. The previous editions of the science page are available on our website.

Key points from this week edition

We analyzed performance records from 16 sow farms that were vaccinated with PRRS virus and experienced a PRRS virus infection.

Production dropped until the 6th week post-outbreak with a second decline between the 11th and 18th week post-outbreak.

We calculated an average decrease of 1.92 weaned pigs per sow (min=0.51, max=3.72) per year attributable to changes in farrow rate and prewean mortality.

The full report on production losses from endemic PRRS farms in the US is available.
