Porcine epidemic diarrhea virus (PEDv) has been confirmed on more than 1,700 swine premises across 20 states, according to the latest “Hog Outlook” report from the University of Missouri. Some industry observers put losses attributed to PEDv at 4 million over the last seven months.Read, “Hog weights jump to compensate for PEDv losses.”
Now a group of experts has released a new study to the American Association of Swine Veterinarians (AASV), giving a new look at building immunity through intentional sow herd exposure to PEDv.
In their report, available here, the authors explore the most efficient concepts, procedures and material to increase herd exposure. They were successful in infecting all sows and gilts on the premises by exposing them to virus-containing fecal material.
The results show promise for protecting piglets.
