Soluble Fiber and Insoluble Fiber Regulate Colonic Microbiota and Barrier Function in a Piglet Model

Figure 4

Colonic weight (a) and weight index (b) in different groups . The colonic weight index was calculated by colonic weight index (%) = colonic weight (g)/body weight (g) × 100%. Letters above the bars (a, b) indicate statistical significance among the four groups. CON, control; IDF, 1% insoluble fiber; SDF, 1% soluble fiber; MDF, 0.5% insoluble fiber +0.5% soluble fiber.
