23 bacteria and Butyrivibrio proteoclasticus B316 bacteria were the dominant populations, accounting for 16% and 11%, respectively.

10% increased the growth rates of ruminal noncellulolytic bacteria including Bacteroides amylophilus, Megasphaera elsdenii, Prevotella ruminicola
and Selenomonas ruminantium and ruminal cellulolytic bacterium, Fibrobacter succinogenes which is considered to be the most effective in utilizing cellulose from plant tissues (Miller, 1959).
Among major rumen bacteria, Fibrobacter succinogenes, Ruminococcus flavefaciens, Ruminococcus albus, Butyrivibrio fibrisolvens, Prevotella ruminicola
, Eubacterium cellulosolvens and Eubacterium ruminantium are recognized as fibrolytic bacterial species (Stewart et al.
