This study was implemented to evaluate the effects of predigestion for some local forages: alfalfa hay (AH), barley straw (BS), reed (R) and combination of these forages to enhance nutritive value by predigestion to the cell wall with different commercial fibrolytic enzyme powder levels at 0, 1, 2, and 3% by socking it for 12h. Results indicated high significant increases (P<0.01) in dry matter content (DM) and inorganic matter (Ash) for predigestion to all forages with enzyme, wile they were high significant reduce (P<0.01) in organic matter (OM) and neutral detergent fiber (NDF) for all treated forages with enzyme, but not affected on CP and ADL content. In vitro trial indicated increase in dry matter digestibility (DMD) and organic matter digestibility (OMD) (P<0.01) for predigested alfalfa hay (AH) and not significant increases for the other forages with sheep rumen liquor. When used goat rumen liquor, OMD for alfalfa hay was significant increases (P<0.01). In conclusion: Alfalfa hay had the best values for in vitro DMD and OMD. Wild reed (R) had the lowest values. The level of enzyme was not significant and the best improvement with the level 3% on in vitro DMD and OMD. There was no significant differ for in vitro DMD and OMD when used sheep or goat rumen fluid.
