  1. Exp. experiment, SEM standard error of mean, FCS fecal consistency score, ADG average daily gain, ADFI average daily feed intake
  2. a,bMeans with no common superscript within a row differ (P < 0.05)
  3. x-zMeans with no common superscript within a column differ (P < 0.05)
  4. 1)Data are least squares means of 6 pens, with 8 piglets per pen
  5. 2)Scored subjectively: 0, normal firm feces; 1, soft feces; 2, diarrhea
  6. 3)Applies to all day × treatment combinations
  7. 4)The P values for the day and day × treatment were <0.001 and 0.447, respectively
