Abstract: It was aimed to determine the effect of PFG2 alpha on estrus cervical mucus, total protein, malondialdehide (MDA), vitamin A, plasma MDA, vitamin A, E, ?-carotene, reduced glutation (GSH) and cholesterol levels applied for the synchronization in cows. Seven cows were used in this study. Estruses were synchronized with dinoprost trometamin as a PFG2 alpha analogue. Cervical mucus and blood samples were taken from the cows exasperated. The same cows were taken cervical mucus and blood samples again after 21 days in their usual estrus. The levels of cervical mucus, MDA, total protein, Vitamin A, plasma MDA, cholesterol, ?-carotene, GSH, vitamin A and E were determined. Total protein levels of the cervical mucus that are stimulated by PGF2 alpha were higher compared to natural estrus (P<0.01), however, no difference was observed for vitamin A and MDA levels. Plasma vitamin A, E, ?-carotene, GSH, MDA and cholesterol levels of the same animals were determined, and no difference (P>0.05) was observed between the groups. In addition, positive correlation was determined both in the stimulated and natural estrus cervical mucus and plasma vitamin A levels (P<0.01, P<0.05 respectively), and a positive correlation between natural estrus cervical mucus and plasma MDA levels (P<0.05). As a result, it was considered that PFG2 alpha that is used to stimulate estrus in cows affected cervical mucus total protein level, but had no effect on the other parameters.
