  1. 1Optical density values analyzed by ELISA. Neg means that the O.D. value is below the cut-off established for the technique (<0.300).
  2. 2Serum collected from pigs weaned at 3 to 4 wks of age and fed diets with either 0% or 8% SDPP for 45 days [33]. Serum samples from pigs were stored at −80°C since the experiment was completed (April to October 2006) and retrospectively analyzed for the presence of HEV AB during April to May 2012.
