Microbial profiles of liquid and solid fraction associated biomaterial in buffalo rumen fed green and dry roughage diets by tagged 16S rRNA gene pyrosequencing.

The microbiome of buffalo rumen plays an important role in animal health and productivity. The rumen bacterial composition of both liquid and solid fraction was surveyed using pyrosequencing of the 16S rRNA gene. Sequences were analyzed using taxonomy-dependent clustering methods and revealed that the dominant ruminal bacteria shared by samples belonged to phyla Bacteroidetes, Firmicutes, Fibrobacteres and Proteobacteria.
