  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 samples from pigs were stored at −80°C since the experiment [34] was completed (April to October, 2006) and retrospectively analyzed for the presence of HEV AB during April to May, 2012.
  3. 3Respective control or SDPP groups of pigs were fed diets containing 0% or 8% SDPP for 28 days.
  4. 4Indicated if the pigs were intranasal challenged with PRRSV.
