Öğe Characterization of Oestrous Induction Response, Oestrous Duration, Fecundity and Fertility in Awassi Ewes During the Non-breeding Season Utilizing both CIDR and Intravaginal Sponge Treatments(Wiley, 2010) Ozyurtlu, N.; Kucukaslan, I.; Cetin, Y.Contents The aim of this study was to investigate characterization of oestrous response, onset of induced oestrus, oestrous duration, fecundity and fertility in Awassi ewes treatment with intravaginal sponges and Controlled Intravaginal Drug Release (CIDR) devices in combination with pregnant mare serum gonadotropin (PMSG) under local environmental conditions during the non-breeding season. A total of 62 ewes were divided into three groups. Group CIDR (n = 20) was treated with CIDR devices for 12 days and 400 IU PMSG was injected upon removal of the CIDR. For ewes in Group Sponge (SP) (n = 24), 30 mg fluorogestone acetate was administered to the sheep for 12 days and 400 IU PMSG was injected upon withdrawal of the sponge. Group Control (CON) (n = 18) served as a control group and received no treatment. Adult, intact and sexually experienced Awassi rams were introduced to all groups at the time when the intravaginal devices were removed. There were no significant differences in terms of oestrous response (CIDR: 90%, SP: 87.5%), time to onset of oestrus and duration of induced oestrus between the CIDR and SP groups. The oestrous response of treatment groups was significantly greater (p < 0.05) than in the control ewes. There were no significant differences in pregnancy (CIDR: 70%, SP: 70.8%), lambing (CIDR: 85%, SP: 79.2%) and fecundity rates between ewes treated with CIDR and those treated with sponges. However, pregnancy and lambing rates were significantly (p < 0.05) higher in ewes treated with CIDR or sponges when compared with those in the control group. It was concluded that it is possible to induce fertile oestrus, successful pregnancy and lambing with the treatment of either CIDR or intravaginal sponge in combination with PMSG in Awassi ewes during the non-breeding season.Öğe The effectiveness of combined preventive treatment with Ceftiofur, Oxytocin and PGF2? on fertility parameters in cows(Ecole Nationale Veterinaire Toulouse, 2012) Kaya, D.; Ay, S. S.; Kucukaslan, I.; Beceriklisoy, H. B.; Agaoglu, A. R.; Findik, M.; Ozyurtlu, N.The present study is aimed at evaluating the effectiveness of combined preventive treatment with Ceftiofur Hydrochloride (CHR), Oxytocin (OXT) and PGF(2 alpha) on fertility parameters and puerperal disorder rates in postpartum (pp) dairy cows. A total of 191 Holstein-Friesian cows were divided into four groups. The cows in group I (GI; n=37) and II (GII; n=69) were treated on a daily basis with CHR and OXT for five and three days pp, respectively. Group III (GIII; n=52) was designed as the PGF(2 alpha) group, and group IV (GIV; n=33) served as a control group. The animals in GI, GII, and Gill were given a PGF(2 alpha) analogue on days 15 and 26 pp. Each group was further divided into subgroups of normal parturition (np) and dystocia (d) when the study results were evaluated. It was found that the first service pregnancy rates for the subgroup of dystocia were significantly higher (P<0.05 and P<0.01) in subgroup GII (76.9%) than in GI (30.0%) and GIV (37.5%). Furthermore, the median time to first service and the median time to pregnancy were longer for cows in subgroup GIVd as compared with subgroups GId, GIId, and GIIId (P<0.001; P<0.01). Group II was found to have the lowest endometritis rates after treatment of subgroups-d and -np. No statistically significant difference was found between the groups with regard to cystic ovary rates after treatment (P>0.05). As the treatment with CHR-OXT combined with PGF(2 alpha) on days 15 and 26 was associated to improved uterine involution patterns and reproductive performance, our results suggest that administration of this preventive treatment would be useful, especially for cases of dystocia.Öğe Effectiveness of Thuja occidentalis and Urtica urens in pseudopregnant bitches(B W K Publishing Solutions & Verlag, 2008) Beceriklisoy, H. B.; Ozyurtlu, N.; Kaya, D.; Handler, J.; Aslan, S.The aim of this study was to investigate the effectiveness of Thuja occidentalis and Urtica urens in pseudopregnant bitches. Clinically pseudopregnant bitches (n=38) were assigned per random to groups as follows: Group I: Thuja occidentalis D30 (8 globules, 3 times a day, per os, n=15); Group II: Urtica urens D6 (8 globules, 3 times a day, per os, n=15); Group III: naloxone (control group, 0.01 mg/kg, twice daily, s.c., n=8). Treatments were continued until clinical signs resolved. Animals were classified as no, mild, moderate, and severe (score -, +, ++, and +++) according to the clinical signs of mammary glands and behavioural signs during the study. Bitches were examined at 3-5 days intervals by means of adspection and palpation until clinical signs resolved. Successful recovery rates (100 %) were found in Group I and II. Application of naloxone was found to be successful in only 3 of 8 bitches (37.5 %). Mean duration of treatments in Group I, II and III was 11.6 +/- 4.6 (min-max: 3-18) days, 13.5 +/- 3.7 (min-max: 6-19) days and 14.3 +/- 5.9 (min-max: 10-21) days, respectively. During treatment with Thuja occidentalis D30 and Urtica urens D6, the percentages of bitches with behavioural problems significantly decreased within 3-5 days from 33.3 % to 6.7 % (p=0.033) and from 66.7 % to 33.3 % (p=0.050), respectively. All bitches treated with Thuja occidentalis D30 or Urtica urens D6 showed normal behaviour within 10 days after onset of treatments but 2 bitches in the naloxone group kept showing behavioural signs until Days 15-20 of treatment. Concerning mammary gland scores, treatments yielded significantly higher success rates in Group I and Group II (100 in both groups) compared to the success rate observed in Group III (37.5 %; p=0.012). No side effects were observed during the study. In conclusion, the homeopathic agents Thuja occidentalis D30 and Urtica urens D6 proved to be effective and safe in pseudopregnant bitches.Öğe Effects of CIDR-G and Melatonin Implants, and their Combination on the Efficacy of Oestrus Induction and Fertility of Kilis Goats(Wiley, 2009) Cetin, Y.; Sagcan, S.; Gungor, O.; Ozyurtlu, N.; Uslu, B. A.The objective of this study was to compare the efficiency of oestrus induction protocols on Kilis dairy goats kept on a goat farm situated close to Kilis, Turkey. Eighty goats were assigned randomly into four groups of 20 animals each in a factorial arrangement: (i) untreated control (CON), (ii) melatonin implant (MEL), (iii) CIDR-G (CIDR) and (iv) melatonin implant plus CIDR-G (MC). Experiments were performed in mid-anoestrus season under natural photoperiod environment. The differences among treatment groups in oestrus response were significant. Oestrus response was higher in the MC group than in other groups (p < 0.05). A significant difference was observed in the time interval from cessation of treatment to the onset of oestrus among treatments. The CIDR-G treatment reduced intervals from buck introduction to oestrus. The time to onset of oestrus in both the MC and CIDR groups was significantly shorter, compared with the MEL and CON groups (p < 0.05). The number of does kidding and fertility were not different among treatment groups (p > 0.05). Fecundity was similar among goats in all groups. Prolificacy and twining rates showed similar trends as fecundity rates, with no differences (p > 0.05) between treatments. The results of this study showed that oestrus in Kilis does can be effectively induced by using melatonin and CIDR combined treatment, and fertility will not be adversely affected. However, this treatment did not improve fecundity, prolificacy and twining rates.Öğe Evaluation of endometrial echotexture and cervical cytology in cows during and after treatment of endometritis(Georg Thieme Verlag Kg, 2014) Kucukaslan, I.; Kaya, D.; Emre, B.; Bollwein, H.; Ozyurtlu, N.; Mulazimoglu, S. B.; Aslan, S.Objective: The aim of this study was to evaluate changes in the endometrium by using echotexture parameters during and after treatment of endometritis with intrauterine administration of an intrauterine antiseptic solution (Lotagen (R), 3% metacresolsulphonic acid and formaldehyde) in cows which became pregnant after treatment. Material and methods: According to the severity of endometritis 21 cows were divided into three groups: El (slight, n = 7), E2 (moderate, n = 8), E3 (severe, n = 6). The control group (C, n = 11) consisted of cows without endometritis that did not receive an intrauterine medication. A software (Bs200 Pro (R)) was used to evaluate echotexture parameters Contrast (CON), Gradient (GR), Homogeneity (HUM), Mean Gray Level (MGL) of images taken during the examinations at hours (h) 0, 1 and 6 and days (d) 2, 3, 5 and 10. Results: At 0 h, GR was significantly lower in group E2 than in groups El and C (p < 0.05). There was an increase in GR values between 0 h and 10 d in group E2 and E3, but a decrease during the same time interval in group C (p < 0.05). In contrast, CON values of group E2 were lower (p < 0.05) at 0 h compared to other timepoints of examination and lower than in group C. HOM values were lower (p < 0.05) in groups El, E2 and E3 than in group Con d 5 and d 10. HUM values were higher at 1 h compared to 6 h, d 2 and d 10 in group E3 (p < 0.05). By contrast to GR values, HUM values were higher in group C at 6 h and d 10 than they were in group E3. MGL values of group E2 were higher (p < 0.05) than in group C until d 10 and higher (p < 0.05) in group E3 than in group C at 6 h after treatment. In group E2 an increase of MGL values until d 2 was followed by a decrease (p < 0.05). Conclusion: Echotexture parameters determined by the evaluation of sonographic B-mode images reflect changes in the endometrium and could be used for the evaluation of the recovery period after treatment of endometritis.Öğe Synchronization of Estrus Using FGA and CIDR Intravaginal Pessaries During the Transition Period in Awassi Ewes(Medwell Online, 2008) Zonturlu, A. K.; Aral, F.; Ozyurtlu, N.; Yavuzer, U.The objective of this study was to investigate the efficiency of synchronization using different progesterone treatments during transition period from the non-breeding to the natural breeding season. Thirty-four non-lactating Awassi ewes were randomly assigned to two groups, treated with fluorogestone acetate (FGA group, n = 19) or controlled internal drug release devices (CIDR group, n = 15) for 12 days. After pessary and sponges removal, all ewes received an intramuscular injection of 300 IU. eCG. There was no significant differences between treatments for ewes in estrus (FGA: 84.2%, CIDR: 86.6%). The onset of estrus from progestagen treatments, FGA and CIDR groups was (mean +/- S.D.) 45.00 +/- 1.00 and 36.00 +/- 3.40, respectively. Interval from the cessation of treatment to the onset of estrus was significantly (p<0.05) longer in FGA, compared to the CIDR. The duration of the induced estrus period did not differ significantly between in 2 treatment groups. Pregnacy rate did not differ (p>0.05) between FGA (52.63%) and CIDR (60.00%). As a result, Estrus synchronization with FGA and CIDR is found to be similar, although the onset time of estrus varies with the use of FGA or CIDR.Öğe Use of Echo-texture Parameters for the Determination of Different Degree Endometritis in Cows and Evaluation of the Recovery Period after Treatment(Wiley-Blackwell Publishing, Inc, 2009) Kucukaslan, I.; Kaya, D.; Emre, B.; Ozyurtlu, N.; Aslan, S.[Abstract Not Available]
