In-vitro/in-sacco evaluation of roughages treated with fibrolytic enzymes

Effect of fibrolytic enzyme treatment on in vitro rumen fermentation and on in sacco degradability of roughages was investigated. The in vitro concentration of total VFA and TCA-N was improved (P<0.01) in treated than in untreated roughages. The in sacco DM and cell wall constituents degradability of wheat straw (WS), maize stovers (MS), bajra stalks (BS) and berseem hay (BH) was improved in enzyme group. The effect of fibrolytic enzymes on the digestibility of nutrients was maximum from MS, followed in order, by BS, BH and WS.
