FIGURE 3

Loading plots of sparse partial least square-discriminant analysis showing the best discriminant bacterial operational taxonomic units (OTU; n = 20; relative OTU abundance >0.04%) and complex carbohydrates (RS, NRS, aNDFOM and ADFOM; n = 4) or nutrients in feces (protein, ash, Ca and P; n = 4). The sPLS-DA identified the best discriminant bacterial OTUs on component 1 at more than 0.04% relative abundance of all (A) OTUs, (B) nutrients and (C) carbohydrates (method = “median”). Colors indicate the treatment groups where the mean abundance of the OTUs, nutrients and carbohydrates is maximal. Con, control diet; LA, diet containing lactic acid- treated cereals; Con-Phy, diet with phytase supplementation; and LA-Phy, diet with phytase and lactic acid-treated cereals.
