Effects of feeding Bt and isogenic maize on immune cell counts (×1000/µL) ±SE in growing pigs.

1Isogenic: isogenic maize diet for 110 days. 2Bt: Bt maize diet for 110 days. 3Isogenic/Bt: isogenic maize diet for 30 days followed by Bt maize diet for 80 days. 4Bt/isogenic: Bt maize diet for 30 days followed by isogenic maize diet for 80 days. 5Normal reference range in pigs = 11,000–22,000/µL [20]. 6Normal reference range in pigs = 4,300–13,600/µL [20]. 7Normal reference range in pigs = 200–2,200/µL [20]. xyWithin a row means without a common superscript differ by P<0.05 by means separation using Tukey-Kramer adjustment for multiple comparisons. abcWithin a row means without a common superscript differ by P<0.10 by means separation using Tukey-Kramer adjustment for multiple comparisons.
