Table 1.
Proximate analyses of test diets.
Proximates, fiber, oligosaccharide and amylose content of the commercial grain-containing diet and different formulated test diets after extrusion and fat coating are shown. Diets ordered from left to right in order of increasing total high molecular weight dietary fiber (HMWDF) content.
Table 2.
Measured content of cystine, methionine, cystine+methionine and taurine in the 3 different test diets formulated at 15% enzymatic starch with variable amounts of fiber, fed for 28 days. For comparison, the recommended dietary minimum amino acid levels by the American Association of Feed Controllers (AAFCO) are also shown.

Fecal bile acid content (μmol/g) from dogs after 28 days of feeding each test diet.
Diets ordered from left to right in order of increasing total high molecular weight dietary fiber (HMWDF) content. Data is shown as Mean ± SEM; n = 8 dogs. Different letters indicate significant differences using Tukey’s post-hoc analysis (p < 0.05) after one-way repeated measures ANOVA.

Plasma levels of canine NT-ProBNP (left graph) and cardiac-specific Troponin I (right graph) circulating in dogs after 28 days of feeding each test diet. Diets ordered from left to right in order of increasing total high molecular weight dietary fiber (HMWDF) content. Data is shown as Mean ± SEM; n = 8 dogs. Different letters indicate significant differences using Tukey’s post-hoc analysis (p < 0.05) after conducting a one-way ANOVA.
