The present study was undertaken to determine the effect of graded level of concentrate 0%, 25%, 50% and 75% on the tempertuer and pH in rumen fluid, fauna and fatty acids composition of rumen protozoa in goats under feeding of wild grass. Ruminal tempertur remained high up to 50% level of concentrate ratio. Ruminal pH decreased up to 50% concentrate ratio. Total protozoa number was increased with feeding of concentrate level. Correlation of total protozoa number and Entodinum number was higher in positive. Content of palmitic acids and oleic acids of rumen porotozoa were increased with concentrate ratio. Corerlation of content of oleic acids and Epidinium number was higher in positive. These results suggest that fermentation of feed in the rumen is activates with increase of concentrate ratio. Moreone, it seems that the increase of the total number of protozoa ascribes to the number of Entodinum species and the increase of oleic acids content is due to the increase of Epidinium species.
