    Effect of Different Doses PMSG on Estrus Synchronization and Fertility in Awassi Ewes Synchronized with Progesterone During the Transition Period
    (Kafkas Univ, Veteriner Fakultesi Dergisi, 2011) Zonturlu, Abuzer Kafar; Ozyurtlu, Nihat; Kacar, 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 witha 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.

    Estrous Synchronization with Used CIDR-G Devices in Ewes During Non-Breeding Season
    (Kafkas Univ, Veteriner Fakultesi Dergisi, 2009) Gungor, Orsan; Ozyurtlu, Nihat; Pancarci, Suekrue Metin; Kaya, Mehmet; Zonturlu, Abuzer Kafar; Oral, Hasan; Cetin, Yunus
    The objective of this study was to investigate the efficacy of used controlled internal drug release devices (CIDR-G) on estrous synchronization in ewes. This investigation was conducted in 58 fat-tailed ewes during the non-breeding season. Ewes were divided in to four groups. In Group I, CIDR-G devices were inserted to vagina for 12 d (CIDR group). In Group II, previously used CIDR-G devices were inserted into the vagina for 12 d (U-CIDR). After the intravaginal devices had been removed 500 IU equine chorionic gonadotropin (eCG) was injected intramuscularly (i.m.) into ewes of the CIDR and U-CIDR groups. Ewes in Group III (eCG group), 500 IU eCG was injected im. Ewes in Group IV, served as control and received an injection of 3 mL 0.9% NaCl ( C Group). None of the control ewes expressed estrus. It was found that, 13/15 (86.67%), 10/15 (66.67%) and 1/13 (7.69%) ewes expressed estrus in CIDR, U-CIDR and eCG groups, respectively. The pregnancy rates in the CIDR, U-CIDR and eCG groups were 8/15 (53.33%), 9/15 (60%) and 1/13 ( 7.69%) at first breeding, respectively. The interval from eCG application to onset of estrus was 42.6+/-1.01, 40.13+/-1.35 and 74 h in the CIDR, U-CIDR and eCG groups, respectively. Average progesterone (P4) levels during P4 treatment were 3.28+/-0.28 and 2.62+/-0.14 ng/ml in the CIDR and U-CIDR groups, respectively. It is concluded that, CIDR-G that have been previously used for 12 d could be used for the synchroniation of estrus in ewes during non-breeding season.

    Evaluation of Sheep and Goat Dystocia Cases Submitted to Our Clinic: Etiology, Clinical Approach and Results
    (Harran Üniversitesi, 2017) Korkmaz, Ömer; Çetin, Hayrettin; Atlı, Mehmet Osman; Zonturlu, Abuzer Kafar
    In this study, etiology, causes, treatment and results of treatment of sheep and goat dystocias seen in and around Şanlıurfa between 2003 and 2010 were evaluated. The study material consisted of 87 cases of which 57 were goats and 30 sheep brought to our clinic with dystocia complaints. All cases were divided into two groups: maternal (n=39, 44.83%) and fetal (n=48, 55.17%). Prolapsus vagina, inadequate cervical dilatation (ringwomb) and uterine inertia were observed in maternal dystocia cases while multiple pregnancy and fetal disturbances were detected in fetal dystocia cases. Cesarean operation conducted in 43 cases, extraction force in 40 cases and laparotomy in one case were performed in the treatment. As a result of caesarean operation were obtained 53 live, 27 dead fetus. With the extraction force, 25 live and 27 dead fetus were removed.

    Investigation of some biochemical parameters and mineral substance during pregnancy and postpartum period in awasi ewes
    (Kafkas Üniversitesi Veteriner Fakültesi, 2009) Gürgöze, Sema Yaralıoğlu; Zonturlu, Abuzer Kafar; Özyurtlu, Nihat; İçen, Hasan
    The aim of this study was to investigate the possible effects of the reproductive status on the serum chemistry and mineral substance in Awassi ewes at 21, 120 and 145 days of pregnancy and 7 and 14 days postpartum. All blood profiles were determined in 20 healthy pregnant Awassi ewes. Serum urea, total bilirubin, direct bilirubin, total protein, albumin, alanine transaminase (ALT), creatine kinase (CK) were higher in pregnancy while serum glucose, creatinine, alkaline phosphatase (ALP), P and Ca levels were higher in lactation. Neither the pregnancy nor the lactation effected AST, LDH, Fe and Mg levels. Lower (P<0.001) serum glucose levels were recorded on days 21, 120 and 145 of pregnancy, compared to days 7 and 14 postpartum. Blood total protein levels (P<0.01) decreased, while total bilirubin and direct bilirubin (P<0.01) increased, especially at 120 days of pregnancy. Serum urea (P<0.001) and ALT (P<0.05) levels increased on day 21 of pregnancy, compared with any other stages of gestation and days 7 and 14 postpartum. While serum CK (P<0.01) and albumin (P<0.001) levels were significantly higher on day 145 of gestation, serum ALP (P<0.05), and creatinine (P<0.001) levels were higher at 14 day postpartum. Although without statistical significance, the highest LDH concentration was found in the lactation periods. The mean level of serum Ca at 14 days postpartum was significantly (P<0.001) higher than prepartum period. The highest Mg levels were found at 14 days postpartum. Serum P levels were lower at 120 days of gestation and were higher 14 days postpartum. A gradual increase in serum Fe levels was recorded during pregnancy when compared to day 7 and 14 postpartum but it was not statistical significance. In conclusion, the present findings suggest that serum glucose, creatinine, urea, total bilirubin, direct bilirubin, total protein, albumin, ALT, CK, ALP, Ca and P concentrations of the ewes similarly fed, could alter depending on gestation period and parturition which have to be taken in to consideration for the correct interpretation of serum chemistry and elements status.
