Bacterial composition and differential taxa between HADG and LADG groups in different periods. A and B The relative abundances of the rumen bacterial community at the phylum and genus levels during the preweaning period. D and E The relative abundances of the rumen bacterial community at the phylum and genus levels during the postweaning period. C and F The significantly different bacterial taxa between HADG and LADG groups during the preweaning (C) and postweaning period (F). HADG, higher average daily gain group; LADG, lower average daily gain group
