In this investigation pH values, protozoa counts, protozoa volumes and protozoa species were determined in the rumen contents of Angora goats fed with different rations. For this purpose 4 animals with 2 years old and with permanent rumen cannula were used.

Feeding the animals was performed according to 4x4 Latin Square desing. Each animal was fed with four different types of rations (I, II, III, IV); alfalfa straw (100 %), alfalfa straw + concentrate mixture (80 : 20, 60; 40, 40: 60) respectively.

pH value of rumen content was found to be highest (1.22) before feeding, but dropped to 6.21 at the 6 th hour and. incereased again (QA2) at the 10 th hour following the feeding.

The protozoa counts and their volumes of rumen contents showed a para-lelism to the declination in pH values. Total 10 protozooon species were identified, but "Entodinium minimum" was predominant at each sampling time.

The differences between pH values and protozoa counts were generally found to be higly significant (p<0,01). The protozoon counts and their volumes were higher for the animals fed IV th ration than for the animals having the other rations.
