Modern age agriculture nor confinement buildings have anything to do with pigs being cannibals. Pigs have been cannibals since the beginning of time. This is why criminals have used pigs as means of disposing of murder victims through the years.
The practice of introducing dead pigs back to the mothers is not a new-age, modern agricultural method of immunization. In fact, as a 4-H livestock producer in the early 1980's I had pigs infected with Transmissible gastroenteritis (TGE) in my herd. At that time, I had no pigs in confinement; all of them were raised on dirt outside. TGE and the current PEDv are cousins for which no vaccine is currently available.
Animal diseases always have and always will be a component of producing animals for food. Today, pig farmers of all sizes and types are breaking with PEDv. It does not discriminate against one type or size.
I would close by reminding all of you that if you have ever been given a vaccination, you to have had the disease given to you as a means of immunization. Fortunately vaccine companies have made it convenient for humans so we can get it in the form of a shot instead of eating it from another diseased human. Both physiological processes work in the same manner.
It is a time to celebrate the accomplishments of American Agriculture in that these disease outbreaks have been rare thanks to modern technologies. However, it is but a grim reminder that when you raise livestock, you will inevitably have deadstock.
