Figure 1From: The effect of wheat prebiotics on the gut bacterial population and iron status of iron deficient broiler chickens Summary of in vitro bioavailability results. Red columns - Ferritin concentrations in Caco-2 cells exposed to samples (ng of ferritin/mg of protein). Values are means +/− SD (n = 6), P < 0.05. Blue columns - Sample Fe concentration (means +/− SD (n = 3), P < 0.05, ppm). WM = wholemeal.Back to article page
