Fig. 4From: Integrated rumen microbiome and serum metabolome analysis responses to feed type that contribution to meat quality in lambsHierarchical clustering analysis for identification of different metabolites in lamb serum by comparison of the grass and concentrate groups following positive mode ionization. Each column in the figure represents a sample, each row represents a metabolite, and the color indicates the relative amount of metabolites expressed in the group; Red indicates that the metabolite is expressed at high levels, and green indicates lower expressionBack to article page
