Blood Serum Thyroid Hormone Levels And Rumen Protozoa In Merino Rams At Different Environmental Temperatures

Öz

In the study, a total of 18 merino rams which were at the same age. similar body weight and healthy were
used. The levels of thyroid hormone were measured in blood serum, ruminal pH and protozoa counl were determined
and the species of protozoon were identified in rumen contents at different environmental temperatures in the dif·
ferent seasons. The levels of blood serum total thyroxin and lolal triiodothyronine, ruminal pH and protozoa count
were found to be lower amounts in the animals at 23.T'C and 20.0 % relative humidity (RH), when compared to the
same values of the rams at 3.2"C and 63.3 % RH. The percentages of the protozoon species did not significantly aiter
depended on the environmental temperatures in the experiment.
