    (2004) Aslan, Selim; Kaçar, Cihan; Zonturlu, Abuzer K.; Macun, H. Ceyhun; Saban, Erdal; Özyurtlu, Nihat
    Bu çalışmanın amacı, koyun ve keçilerde gebelik tanı yöntemi olarak kullanılan servikal mukus kaynatma testinin saha koşullarında uygulanabilirliği ve doğruluk oranının araştırılmasıdır. Çalışmada 50 baş Akkaraman ırkı koyun ve 50 baş Ankara keçisi materyal olarak kullanıldı. Servikal mukus testi ile koyunlarda % 80 doğruluk oranı, %73.3 sensitivite, % 82.9 spesivite, % 64.7 pozitif tanımlama oranı ve % 87.9 negatif tanımlama oranı elde edildi. Keçilerde ise bu oranlar sırasıyla % 70, % 60, % 72.5, % 35.3 ve % 87.9 olarak bulundu. Ayrıca korpus luteum büyüklüğü ve progesteron değerleri arasındaki korelasyon araştırıldı. Gebe ve gebe olmayan tüm hayvanlar içinde sadece gebe olmayan koyunlarda korelasyonun önemli olduğu (r=0.58; p<0.05) tespit edildi. Bunlara ilaveten yapılan vaginal sitoloji değerlendirmesinde gebe ve gebe olmayan hayvanlar arasında hücre kompozisyonu bakımından ayırıcı bir farklılığın olmadığı saptandı. Sonuç olarak, koyun ve keçilerde yapılan bu çalışmada servikal mukus kaynatma testiyle koyunlarda gebeliğin tanısında keçilere göre daha yüksek oranlar elde edilebileceği ve bu yöntemin saha koşullarında uygulanabileceği kanısına varıldı.

    Association between metabolic indicators and clinical endometritis during the transition period in Brown Swiss cows
    (Polish Soc Veterinary Sciences Editorial Office, 2021) Yazlık, Murat Onur; Çolakoglu, Hatice Esra; Pekcan, Mert; Kaya, Ufuk; Kurt, Serdal; Kuplulu, Şükrü; Kaçar, Cihan; Vural, Rıfat
    The objective of the current study was to evaluate the relationship between the serum macromineral, metabolite profiles, and the clinical endometritis during the transition period in Brown Swiss dairy cows. Sixty Brown Swiss dairy cows were used in the present study. Blood samples collected at d 10 (+/- 4) antepartum and 3, 10 and 30 (+/- 4) days in milk (DIM) to determine calcium (Ca), phosphorus, glucose, cholesterol, non-esterified fatty acid (NEFA) levels. Beta-hydroxybutyric acid (BHB) concentration measured during the postpartum period. Receiver operating characteristics (ROC) curves were used to determine the cow-level thresholds for the subsequent development of clinical endometritis. In addition, pairwise comparisons were made of the area under the curve (AUC) of ROC curves for the thresholds of NEFA, Ca, and glucose predicting clinical endometritis. The mean Ca concentration at 3 DIM was 8.85 +/- 0.20 mg/dL in healthy cows compared to 8.30 +/- 0.22 mg/dL in cows that subsequently developed endometritis (P < 0.05). NEFA concentrations at 10 DIM and BHB concentration at 10 and 30 +/- 4 DIM were higher (P < 0.05) in cows that subsequently developed endometritis. Serum NEFA concentration at 10 days postpartum is the best predictor for diagnosis of clinical endometritis with the AUC values of 0.741. The cows with clinical endometritis also had significantly higher values of glucose at 3 DIM and lower BCS at 10 DIM (P < 0.05). While 58.6% of the cows that developed clinical endometritis were cyclic, 64.5% were cyclic in healthy cows at 30 +/- 4 DIM. Serum NEFA concentration was the only risk factor for clinical endometritis at 10 DIM. In addition, a decrease in serum Ca at 3 DIM and increase in NEFA and BHB concentrations at 10 and 30 +/- 4 DIM may be associated with clinical endometritis and delayed resumption activity on the ovaries.

    Effect of different doses PMSG on estrus synchronization and fertility in awassi ewes synchronized with progesterone duringthe transition period
    (Kafkas Üniversitesi Veteriner Fakültesi, 2011) Zonturlu, Abuzer Kafar; Özyurtlu, Nihat; Kaçar, Cihan
    The aim of the present study was to evaluate different of doses PMSG on estrus synchronization and fertility in Awassi ewes synchronized with progesterone during The transition period. A total of 92 ewes were used in this experiment. All ewes were treated with a vaginal sponge containing 30 mg fluorogestone acetate (FGA) inserted into the vagina of the ewes for 12 days. All animals were divided into four groups randomly and a single intramuscular (IM) dose of PMSG (group 1, 300 IU, n=21; group 2, 400 IU, n=27; group 3, 500 IU, n= 25), group 4 (n=19) was injected with 1 ml normal saline solution and as served control group at time of sponge removal. The interval between the withdrawal of the sponges and estrus was observed 40.82±1.21 h, 40.20±1.14 h, 38.7±1.07 h and 41.79±1.72 h in groups 1, 2, 3 and the control group, respectively. Estrus responses were similar in all groups (group 1, 81.0%; group 2, 92.6%; group 3, 92.0%; control group, 73.78%). There were no statistically significant differences (P>0.05) between the treatment groups and the control group for the onset of estrus or estrus response. The duration of estrus was shorter in group 1, compared to the control group (24.9±0.85 hr vs. 29.07±1.31hr), and that this difference was statistically significant (P<0.05). Pregnancy rates were 82.35%, 80.0%, 82.60% and 78.5% in groups 1, 2, 3 and the control group, respectively. Lambing rates were obtained 100.0% among all the groups, or litter size (1.07 to 1.21) did not differ between the treatment groups and the control group. As a result, different doses of PMSG in Awassi ewes synchronized with progesterone during the transition period had similar effect on estrus synchronization and fertility parameters.
