Effects of finely ground wheat bran on ileal digesta and fecal short-chain fatty acids of sows. (A) Acetate, propionate, and butyrate concentrations in ileal digesta. (B) Acetate, propionate and butyrate concentrations in feces. Values are presented as mean ± SEM (n = 6). ^{a, b} Means without common letters differ at P < 0.05. CON = a corn soymeal diet; CWB = diet contained coarse wheat bran with particle size of 605 μm; FWB = diet contained fine wheat bran with particle size of 438 μm; SEM = standard error of the mean.
