Least squares means of on basal short-circuit current (I_SC), transepithelial resistance (R_T), and electrophysiological responses to glucose addition of the isolated mucosa from the distal jejunum of broiler chickens fed diets with DON or DON and mycotoxin deactivator (B)¹

¹CON, control diet. Values are least square means and pooled SEM; n = 10.

²Glucose addition to a final chamber concentration of 5 mmol/L; ΔI_SC is the difference between the maximal I_SC value obtained from 2 min after glucose addition and the basal value determined 1 min before glucose addition; ΔR_T is the difference between the basal R_T 1 min before glucose addition and the R_T value obtained from 2 min after glucose addition.

^a,bLeast square means with no common superscripts differ significantly between groups.
