Fig. 5From: The gut microbiota in young and middle-aged rats showed different responses to chicken protein in their dietSpecific phylotypes of gut bacteria in response to diet shift using LEfSe. a Young group; b Middle-aged group. The left histogram shows the LDA scores computed for features at the OTU level. The right heatmap shows the relative abundance of OTU (log 10 transformed). Each column represents one animal and each row represents the OTU corresponding to left one. The color intensity scale showed the relative abundance of OTU (log 10 transformed), yellow denotes an high relative abundance of OTU while black denotes a low relative abundance of OTUBack to article page
