From: Inclusion of purified dietary fiber during gestation improved the reproductive performance of sows
Microbiota alpha-diversity in feces of sows fed different dietary fiber levels at different gestation stages. Sow was regarded as the experimental units (n = 6). a Observed species; b Shannon index and c Chao 1 index. 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. Columns with different letters a,b,c denote P < 0.05
