Anyone involved in raising pigs is aware of porcine circovirus type 2 (PCV2), but new on the scene is porcine circovirus type 3 (PCV3). Although the two viruses are both circular DNA viruses in the same family, they are separate and distinct.
“When you look at the two viruses from a molecular level, they’re very different,” Emily Byers, DVM, Prestage Farms, told Pig Health Today. Her extensive experience involves the virus in a gilt-acclimation site tied to a 7,500-head sow farm and the related down-stream grow/finish production.
