Abstract

The present investigation was undertaken to study the effect of different levels of exogenous fibrolytic enzymes applied on untreated and urea fermented wheat straw on the digestion kinetics of DM and NDF. The untreated wheat straw and the enzyme treated wheat straw had comparable chemical composition while urea treated wheat straw with urea  (3.5:96.5) resulted in higher total ash associated with simultaneous decline in organic matter content, The proportion of rapidly soluble fraction, degradation rate and effective degradation for DM and NDF was highest in case of urea fermented wheat straw treated with 0.2% enzyme level but  the effect was not significant from the fermented wheat straw treated with 0.2% enzyme level.The insoluble but degradable fraction for both DM and NDF also varied in different enzyme level treatments but its value was highest in case of untreated wheat straw as compared to enzyme and urea treated wheat straw.
