Fig. 3From: Preweaning period is a critical window for rumen microbial regulation of average daily gain in Holstein heifer calvesAlpha and beta diversity between HADG and LADG groups in different periods. A and B Alpha diversity (Chao and Shannon indices) of rumen bacteria between HADG and LADG groups during the preweaning period. C and D Alpha diversity (Chao and Shannon indices) of rumen bacteria between HADG and LADG groups during the postweaning period. E Beta diversity of a principal coordinate analysis (PCoA) based on Bray–Curtis dissimilarity matrices between HADG and LADG groups during the preweaning period. F Beta diversity of a principal coordinate analysis (PCoA) based on Bray–Curtis dissimilarity matrices between HADG and LADG groups during the postweaning period. HADG, higher average daily gain group; LADG, lower average daily gain groupBack to article page
