Correlation plot showing Spearman’s correlation between microbial Amplicon Significant Variables (ASV) and Volatile Fatty Acids (VFA) of an indigenous chicken breed fed a diet supplemented with dehydrated black soldier fly larvae and live black soldier fly larvae over the period 39–174 days of age. Only significant associations between ASV and VFA are shown (FDR < 0.05). The intensity of the colors represents the degree of correlation, where blue represents a negative degree of correlation and red represents a positive correlation
