This experiment was conducted to investigate the effects of Natuzyme plus multi enzyme atdifferent inclusions on fermentibility, degradability and digestibility of alfalfa hay. The treatments consisted of l)control group, 2)0.5 g enzyme per Kg of alfalfa hay and 0.75 g enzyme per Kg of alfalfa hay. A Completly Randomized Design(CRD) was used for analyzing data. In Vitro gas production and In Situ nylon bag techniques were used for measuring of fermentibility and degradability. Four heads of fistulated animal(mature Taleshi steers)were used for degradability measurement of DM , NDF and ADF. Digestibility of alfalfa hay were performed by total collection of feces method on 4 heads of Shal mature ram. No significant difference was obtained in gas test results. The effect of enzyme levels on degradability of DM, NDF and ADF at all incubation times were significantly different(p0.05). A positive correlation was obtained between levels of enzyme and degradability of DM, NDF and ADF at all incubation times. The digestibility of DM, OM, NDF and ADF in 0.75 g enzyme per Kg of alfalfa hay group were higher than other treatments significantly(p0.05). Results of this research indicated that using 0.75 g/Kg DM Enzyme significantly improved in situ degradability and in vivo digestibility of alfalfa hay
