Figure 2From: Effects on boar semen quality after infection with porcine reproductive and respiratory syndrome virus: a case reportEffect of a PRRSV infection in routine semen production. Eleven boars were monitored over a period of −4 to 4 weeks post-infection (wpi) on the ejaculate parameter: volume (A), sperm concentration (B), and percentage of motile spermatozoa (C). Significant levels in ejaculate volume (P = 0.417), sperm concentration (P = 0.788), and motility (P = 0.321) between production weeks were not observed.Back to article page
