SEM, standard error of the mean.

¹⁾Least squares means for eight pigs per treatment.

²⁾CP16, corn-SBM-based diet (early weaning CP 16%/late weaning CP 15%); CP17, corn-SBM-based diet (early weaning CP 17%/late weaning CP 16%); CP18, corn-SBM-based diet (early weaning CP 18%/late weaning CP 17%); CP19, corn-SBM-based diet (early weaning CP 19%/late weaning CP 18%); CP20, corn-SBM-based diet (early weaning CP 20%/late weaning CP 19%); CP21, corn-SBM-based diet (early weaning CP 21%/late weaning CP 20%).

³⁾L, linear; Q, quadratic.

⁴⁾Diarrhea score: 0 = normal feces, 1 = moist feces, 2 = mild diarrhea, 3 = severe and watery diarrhea.
