TABLE 2.
Fecal output, fecal nitrogen, and cecal characteristics of male mice fed a 45%-fat diet with or without HAMRS2 supplementation for 10 wk1
| Variable | Control | HAMRS2 | P2 |
| 48-h Fecal output,3 mg | 517 ± 23.0 | 840 ± 33.5 | <0.0001 |
| Mean 24-h fecal nitrogen,3 mg | 5.74 ± 0.20 | 8.10 ± 0.43 | <0.0001 |
| Mean 24-h dietary nitrogen,3 mg | 88.4 ± 2.36 | 87.6 ± 1.85 | 0.80 |
| Cecal tissue,4 mg | 54.4 ± 2.3 | 83.2 ± 5.8 | <0.0001 |
| Cecal contents, mg | 177 ± 6.3 | 271 ± 12.0 | <0.0001 |
| Cecal pH | 7.9 ± 0.1 | 7.8 ± 0.1 | 0.03 |
| Total cecal SCFAs,5 μmol | 6.15 ± 1.21 | 5.94 ± 0.83 | 0.89 |
Values are means ± SEMs; n = 15 in the control group and n = 14 in the HAMRS2 group unless otherwise indicated. HAMRS2, high-amylose-maize resistant starch type 2.
Derived by using a 2-tailed Student’s t test. P ≤ 0.05 was considered significant.
n = 10/group. Contents were removed from the cecum and tissue weight was recorded.
Contents were removed from the cecum and weight was recorded.
Total SCFAs were quantified by summing concentrations (in millimoles per gram) of acetic, propionic, butyric, isobutyric, valeric, isovaleric, and isocaproic acids and multiplying by total cecal contents (in grams) to obtain total SCFA production in the entire cecal contents.
