Principal Coordinate Analysis (PCoA) showing the Jaccard’s distance matrix between caecal bacterial community compositions of three groups of partridges fed control diet (C) and diets with 25% (TM25) and 50% (TM50) protein substitution levels of Tenebrio molitor meal. Each dot represents one sample. The percentage of variation explained by the plotted principal coordinates is indicated on the axes.
