In Vitro Ruminal Metabolities of Cattle and Buffalo as Affected by Fungal Degradation of Cellulosics

In vitro metabolic profile of cattle and buffalo fungi degrading four nutritively variable cellulosics was studied using 0.5g substrate. Higher (P<0.05) rumen protein N and TVFA contents were assayed due to fermentative activity of cattle than buffalo, though, substrates differed (P<0.05) for nitrogenous metabolites, TVFA and cellulase activity. Buffalo than cattle fungi evolved more ammonia-N due to wheat straw degradability and also exhibited higher cellulase activity (P<0.05) due to all feedstuffs barring pearlmillet stover, on which cattle (P<0.05) excelled buffalo for TVFA concentration. Protein contents in the rumen, irrespective of cellulosics, was higher (P<0.05) in cattle than buffalo. Rumen metabolic profile, irrespective of habitat of fungi, may be discerned with 0.5g substrate size.
