1The intake of non-fiber carbohydrate was 28% in the MNFC group (n = 4) and 14% in the LNFC (n = 4) group; the intake of nitrogen was approximately equal in both groups. 2Analyses were performed in triplicate, except for pH analysis, which was in duplicate. Values are means ± SE. P < 0.05 is considered significant.
