  1. Data are expressed as mean ± largest SEM. Sows were regarded as the experimental units, n = 6 for each treatment. a, b, c denote P < 0.05. CON, basal corn-soybean diet; DF1, wheat bran-rich diet; DF2, DF3, DF4 and DF5 were wheat bran diet supplemented with 1%, 2%, 3% and 4% of FIBER MIX at the expense of wheat bran. Linear contrasts (OPC) analysis was used to test the linear and quadratic effects of dietary fiber levels on microbial parameters of sows
