Dietary fibers with low hydration properties exacerbate diarrhea and impair intestinal health and nutrient digestibility in weaned piglets

Table 11 Spearman correlations between diarrhea index, apparent total tract digestibility (ATTD), short-chain fatty acid (SCFA), and branched-chain fatty acid (BCFA) concentrations in colon contents of weaned piglets

DM dry matter, GE gross energy, CP crude protein, NDF neutral detergent fiber, ADF acid detergent fiber, total SCFA, the sum of acetate, propionate, butyrate, and valerate; total BCFA, isobutyrate and isovalerate; the results in the table are shown as the Spearman correlation coefficient. ^*, ^** stand for P value < 0.05 and < 0.01, respectively
