Abstract

Porcine reproductive and respiratory virus (PRRSV) is endemic in many swine herds. The means by which PRRSV continues to circulate in herds is not well understood. Under experimental conditions, we found that PRRSV is shed in the milk and colostrum of infected dams. Virus-contaminated mammary secretions could play an important role in virus transmission in endemically infected herds.
