1Average ammonium (NH4+; mg/L) and BCFA (mM) production over the control (C; n = 6) and the treatment (TR; n = 9) period in the PC and DC of the canine gastrointestinal tract. Data are presented as mean (±stdev). Statistically significant differences relative to the control period are indicated in bold, whereas significant differences between the test conditions are indicated with a different letter (P < 0.05).
