Effect of feeding isogenic or Bt maize-based diets to pigs from 12 days post-weaning for 110 days on fecal bacterial counts1.

1Bacterial counts are presented as means of log10 CFU g−1 wet weight.2Isogenic - isogenic parent line maize-based diet for 110 days (n = 8 pigs/treatment).3Bt - Bt maize-based diet for 110 days (n = 9 pigs/treatment).4Isogenic/Bt - isogenic maize-based diet for 30 days followed by a Bt maize-based diet for 80 days (n = 10 pigs/treatment).5Bt/isogenic - Bt maize-based diet for 30 days followed by a isogenic maize-based diet for 80 days (n = 10 pigs/treatment).6Computed using the mixed procedure in SAS.
