The research was conducted using rumen fluid obtained from fistulated Ongole grade cattle. This research used randomized complete block design with 6 treatments and 5 replications. The treatments were T0 = control (forage:concentrate = 70:30), T1 = T0 + S. rarak extract 1 mg/ml, T2 = T1 + sesame oil 10%, T3= T1 + sesame oil microencapsulation 10%, T4= T1 + canola oil 10%, T5=T1 + canola oil microencapsulation 10%. The difference in time for taking rumen fluid is used as a block/group. The result showed that the addition of S. rarak extract 1 mg/mL and its combination with canola oil microencapsulation significant decreased (P<0.01) protozoal population and increased (P<0.05) bacterial population especially Anaerovibrio lipolytica, NH 3-N concentration, dry matter and organic matter digestibility. The pH value, total and proportion of VFA, CH 4 production, saturated and unsaturated fatty acids were similar among treatments. It is concluded that the combination of S.rarak extract and oils microencapsulation could modify rumen fermentation but did not affect rumen fatty acid profile.
