Supplementing vegetable oils in dairy ration containing polyunsaturated fatty acid (PUFA) as an energy source tend to increased fatty acid profiles. This study aimed to identify the effect of supplementing vegetable oil encapsulated in Ca-soap and prilled on rumen fermentability and digestibility. The experiment used a 4x4x2 factorial randomized block design with three replications. Rumen liquor was obtained from fistulated dairy cow Frisien Holstein. The first factor was the vegetable-based oil (sunflower, soybean, sesame, and canola), the second factor was the level of protected vegetable oils supplementation (0%, 1%, 2%, and 3%) and the third factor was the protection forms. The results showed that supplementing Ca-soap and prill fat significantly decreased (p<0.05) in rumen fermentability and ration digestibility. The variation of oil used, protection forms and level supplementation were significantly influenced pH score and protozoa population. Interaction effects between two factors were found in volatile fatty acid, ammonia, dry matter digestibility (DMD) and organic matter digestibility (OMD). Interaction effects between three factors were found in total rumen bacteria. It is concluded that Ca-soap and prilled fat-protected vegetables oil addition in dairy ration can be used up to 3% to reach the optimum result and less adverse effect on rumen microbial.
