GIS help - where can I find maps of pig-farming regions in the U.S.?

Question

Hi,

I am doing scientific research that requires me to know where pig/hog farming takes place in the U.S.A. Any help finding a map that shows this would be greatly appreciated. If the data can be loaded as a shapefile that is a plus.

Thanks!

"Breeding Herd Numbers by States"

Map (pdf p.5 of 15) and a lot more Hog stuff.
