Advances in the metabolism and regulation of lactic acids in the rumen

Reviews of the ruminant lactic acidosis indicated that accumulation of lactic acids in the rumen may play an important role in inducing ruminal lactic acidosis, while rumen lactic acids accumulation mainly depends on the degree of balance of rumen producing and utilizing bacteria in feeding high concentrate diets. In this paper, advances in lactic acids metabolism associated rumen bacteria (Butyrivibrio fibrisovens, Streptococcus bovis,Lactobacillus, Selenomonus ruminantium and Megasphaera elsdenii) were discussed, prevention strategies of ruminal acidosis were discussed in purpose to provide reference for further research of lactic acids rumen acidosis mechanism.
