TABLE 2.
Effects of dietary NFC on urinal urea-N excretion and microbial protein synthesis in experiment 1 (n = 10)1.
| MNFC group | LNFC group | p-value | |
| Purine derivatives | |||
| Allantoin (mM/d) | 4.06 ± 0.12 | 3.53 ± 0.07 | 0.01 |
| Uric acid (mM/d) | 1.48 ± 0.05 | 1.28 ± 0.02 | 0.01 |
| Microbial N (g/d) | 3.71 ± 0.11 | 3.23 ± 0.05 | 0.004 |
| UUE (mM/BW⋅kg/d)2 | 5.51 ± 0.37 | 8.71 ± 0.69 | 0.001 |
1The intake of non-fiber carbohydrate was 28% in the MNFC group (n = 10) and 14% in the LNFC (n = 10) group; the intake of nitrogen was about equal in both groups. Analyses were performed in triplicate. Values are means ± SE. P < 0.05 is considered significant. 2UUE, urinal urea-N excretion.
