PCV2 can be shed into semen by infected boars and research suggests that the virus can then be transmitted to gilts and sows by AI causing reproductive failure but there is no evidence that PCV2 in semen has effects on various characteristics of sperm cells.
Effect of distributing primary and secondary antioxidants to the sow during the weaning‐estrus interval
The supply of the antioxidants to the sow during the weaning‐estrus interval significantly reduced both the percentage of immature piglets per litter and the within‐litter variation of birth weights.
