Just before boarding the plane for World Pork Expo (WPX), I received an email to check out a new product by Alltech while I was there. I was going to visit Russell Gilliam, Alltech U.S. swine business manager, anyway, as he and I go way back and we always get a beer at their hospitality tent. But, to be honest, I did not expect anything really new.
