• Select carbohydrates were tested for their effects on glycemic response, true metabolizable energy (TME) content, and in vitro fermentation characteristics using canine and avian animal models. Fructose (F) and sorbitol (S) had relative glycemic responses (RGR) of 3.19 and 12.99 in the canine, compared with values of 41.25 for O2‐012 soluble fiber (O) and 100 for maltodextrin (M). TME values determined in the avian were similar for S, F, and M (3.84, 3.99, and 4.06 kcal/g, respectively). These values were higher (P<0.05) than the value for O (3.33 kcal/g). In vitro fermentation of carbohydrates with dog fecal inoculum indicated no acetate production for any of the carbohydrates tested. Propionate produced/g substrate fermented for O and M, respectively, was 11.08 and 35.92, with no propionate produced by F and S. S produced the highest (P<0.05) butyrate concentration (245.11 mg/g) with values for all other substrates being similar (avg., 53.93 mg/g). These carbohydrates vary widely in physiological attributes, but are relatively similar in energy value.
