The aim of this study was to demonstrate effect use of probiotic that contains many of bacteria such as Clostridium butyricum, Bacillus subtilis, Bacillus licheniformis estimate the digestion coefficient of dry and organic matter. The concentration of ammonia nitrogen, use of 3 treatments, to measurement of percentage of dry matter ,organic matter, the amount of metabolized energy, the percentage of protein, and the total numbers of anaerobic bacteria in the rumen fluid. The results showed that there were no significant differences between all treatments in the character the percentage of organic matter digestibility (OM%) and the percentage of dry matter and organic matter(DM), and no differed significantly from each other in the organic matter digestibility coefficient (IVOMD). When the result for (IVDMD) recorded high differed between treatment so each treat of probiotic (T2 and T3) superiority on treat control (T1). also the results of the statistical analysis to the (NH3N) showed a highly significant superiority of the two probiotic treatments over the control treatment, as the averages reached 0.48, 0.69, and 0.81 for both the control treatment and the probiotic at concentrations of 0.02 and 0.04, respectively. The results of the statistical analysis of the protein percentage showed a highly significant value of p<0.01 The probiotic treatment with a concentration of 0.04 and 0.02 was significantly different from the control treatment the control treatment and the probiotic for both concentrations reached 2.97, 4.30 and 5.07%, respectively. The statistical analysis indicated that there was no significant effect of using a probiotic in estimating the amount of metabolized energy for each treatment, The results of the statistical analysis for the number of microorganisms showed that the two coefficients were superior. The probiotic treatment was significantly superior to the control treatment, as the numbers of bacteria reached 72.33, 196.66, and 228.33 Bacterial colony units/ml of rumen fluid for both the control and probiotic treatments at concentrations of 0.02 and 0.04, respectively.
