Comparison of Pregnancy Rates after Short - Term and Long -Term Synchronization Protocol in Ewes- Pilot Study

The objective of the study was to compare pregnancy rates after short-term and long-term synchroniza-tion protocol in Kivircik ewes. Ewes (n=54) were randomly divided into two synchronization groups as ST (short-term; n=27) or LT (long-term, n=27). Intravaginal sponge inserted on same day (D0) both groups. It removed at 7 days (D7) group 13 (D13) group. All ewes received 450 IU eCG 75 μg d-cloprostenol time removal. characteristics vaginal discharge evaluated following withdrawal. For protocols, 5 fertile rams per 27 used for natural mating overall estrous response rate 88.9% 64.8%, respectively. Following synchronization, (94.7% vs. 85.7%, respectively) (63.1% 65.7%, similar multiparous nulliparous Although reduced severe vaginitis from 48.1% 25.9%, not different protocols. Nulliparous had a higher (48.6% 15.8%) than However, alteration vagi-nal severity depending parity did affect (66.7%) (63.0%) Therefore, can be small flocks.
