Description
Sows pass protection against a deadly piglet diarrhea virus through colostrum, and a 2026 study from Ping Chen tracks those antibodies across many sample types. The research article follows responses to porcine epidemic diarrhea virus in infected pigs and in pregnant sows under different immunization strategies on commercial farms.
Antibody tests showed piglets seroconverted one week after infection, peaked within three weeks, and stayed detectable for up to thirty-one weeks afterward. In more than a thousand sow samples, blood antibody levels correlated strongly with colostrum levels, most tightly on the day of farrowing. Mouth and rectal swabs also tracked colostral antibody of one class, offering easier ways to judge maternal immunity.
