ROLE OF FIBER AND NON FIBROLYTIC BACTERIA IN FEED DIGESTION IN BOVINE RUMEN-AN OVERVIEW

In developing countries like India, ruminants fed with lignocellulosic feed. It contains cellulose, hemicelluloses and lignin. Ruminants can utilize these particles with the help of microbial population present in rumen. Among these, bacterial population play key role in feed digestion. The fibrolytic bacteria degrades insoluble fiber into soluble sugars and non fibrolytic bacteria associates with them converts soluble sugars into metabolic products, thereby helps to control feedback inhibition of fiber degrading bacteria. Hence, it is important to understand the association between fiber and non fiber degrading bacteria. In this review, we discussed about predominant fiber degrading and non fiber degrading bacterial species and their association.
