Abstract

The current In vitro study was carried out to investigate the effect of replacing green maize (darawa) with crude olive cake or treated silage with or without fibrolytic enzymes; on nutrients digestibility, rumen fermentation, pH, ammonia nitrogen and gas production. Nine TMR with different replacement ratios were formulated and tested In vitro as follow: C: control group (50% concentrate: 50% darawa), G1: 50% concentrate: 25% of darawa replaced with crude olive cake ratio, G2: 50% concentrate: 25% of darawa replaced with untreated olive cake silage, G3: 50% concentrate: 25% of darawa replaced with treated olive cake silage, G4: 50% concentrate: 50% of darawa replaced with crude olive cake, G5: 50% concentrate: 50% of darawa replaced with untreated olive cake silage, G6: 50% concentrate: 50% of darawa replaced with treated olive cake silage, G7: 50% concentrate:75% of darawa replaced with crude olive cake, G8: 50% concentrate: 75% of darawa replaced with untreated olive cake silage, G9: 50% concentrate: 75% of darawa replaced with treated olive cake silage. Total gas production (TGP) and Dry matter digestibility were recorded the highest values when replaced 25% of darawa with crude olive cake, untreated or treated olive cake silage, whereas TGP and dry matter digestibility were decreased at level 75%.  Moreover, the highest NH3-N concentration (37.63 mM) was observed when replacing 25% of darawa with untreated olive cake silage (G2). Also, NDF and ADF digestibility were enhanced in treated groups compared with control group. From results it can be concluded that using fibrolytic enzymes and ensiling processing led to enhance fiber fractions digestion in olive seeds cell wall. Also, there is high positive effect when replacements darawa with olive cake at level 75% % regarding to reduce gas production and increase NDF and ADF digestibility.
