Effect of psyllium on plasma concentration of glucose, breath hydrogen concentration, and fecal composition in calves with diarrhea treated orally with electrolyte solutions.

We investigated the effect of adding psyllium to a standard electrolyte solution in 10 calves with diarrhea. The calves were tested with the standard solution on one day and standard solution plus psyllium on the alternate day. The order of treatments was randomized. Psyllium converted the solution into mucilage, but did not affect fecal consistency. Mean +/- SEM area under the glucose absorption curve was lower for mucilaginous than for nonmucilaginous solutions, 2.1 +/- 0.62 vs 3.75 +/- 1.18 mmol.h, respectively, but the difference was not significant. The area under the breath hydrogen curve was marginally lower for mucilaginous than nonmucilaginous solutions, 102 +/- 20 and 209 +/- 60 ppm.h, respectively. The usefulness of such decreased bacterial fermentation is doubtful.
