İvesi Irkı Koyunlarda Prepartum Vitamin E/Selenyum ve Melatonin Tedavisinin Uterus İnvolüsyonu Üzerine Olan Etkileri

Öz

Bu çalışmanın amacı, prepartum dönemde Vitamin E, Selenyum ve Melatonin uygulamalarının İvesi ırkı koyunlarında uterus involüsyonu üzerine etkilerini araştırmaktı. Çalışmaya tekil gebeliğe sahip toplam 24 koyun dahil edildi. Beklenen doğum zamanlarından 15 gün önce koyunlar rastgele üç gruba ayrıldı. Grup VE’deki koyunlara (n=8) intramüsküler yoldan Vitamin E ve selenyum uygulandı. Grup M’deki koyunlara (n=8) 18 mg melatonin içeren subkutan kulak implantı uygulandı. Grup C’deki koyunlar (n=8) ise kontrol grubu olarak kullanıldı ve bu gruba herhangi bir tedavi uygulanmadı. Uterus involüsyonlarının tamamlanma süresi Grup VE, Grup M ve Grup C için sırasıyla 20,57±1,21; 19,13±1,13; 18,67±1,09 gün olarak tespit edildi (p>0,05). Uterus çapları Grup VE, Grup M ve Grup C için sırasıyla 9,66±0,59; 9,54±0,35; 7,95±0,22 olarak belirlendi. Doğum sonrası 3. günde Grup VE ve Grup M'deki uterus çapları, Grup C'den anlamlı derecede büyük tespit edildi. (p<0,05). Ortalama dış karunkular çapları Grup VE, Grup M ve Grup C için sırasıyla 1,93±0,10; 1,60±0,10; 1,65±0,07 olarak ölçüldü. Grup VE'deki ortalama dış karunkular çapları, Grup M ve Grup C'den anlamlı derecede büyük olduğu görüldü (p<0,05). Gruplardan bağımsız olarak; 3. gündeki ortalama dış karunkular çapları, 6. güne kıyasla daha büyük olarak tespit edildi (p<0,05). Aynı şekilde 3. gündeki iç karunkular çapları da 6. güne kıyasla daha büyük olarak tespit edildi (p<0,05). Gruplar arasında ortalama iç karunkular çapları açısından fark tespit edilmedi (p>0,05). Sonuç olarak, prepartum dönemde Vitamin E, Selenyum ve Melatonin uygulamasının, İvesi koyunlarında postpartum uterus involüsyon süresinin tamamlanması üzerinde önemli bir etkisinin olmadığı görüldü.

The Effects of Prepartum Vitamin E/Selenium and Melatonin Treatment on Uterine Involution of Awassi Sheep in Hatay

Abstract

The aim of this study was to investigate the effects of prepartum Vitamin E, Selenium and Melatonin treatments on uterine involution in Awassi sheep. The study included a total of 24 ewes with singleton pregnancies. Fifteen days before their expected delivery, ewes were randomly divided into three groups. Group VE (n=8) received Vitamin E and Selenium intramuscularly. Group M (n=8) received a subcutaneous ear implant containing 18 mg of melatonin. Group C (n=8) served as the control group and received no treatment. The mean time for completion of uterine involution in Group VE, Group M, and Group C were 20.57±1.21; 19.13±1.13; 18.67±1.09 days, respectively (p>0.05). Uterine diameters were 9.66±0.59; 9.54±0.35; 7,95±0.22 in Group VE, Group M, and Group C, respectively. Uterine diameters in Group VE and Group M were significantly greater than Group C on Day 3 of postpartum (p<0.05). Mean outer caruncular diameters were 1.93±0.10; 1.60±0.10; 1.65±0.07 in Group VE, Group M, and Group C. respectively. Mean outer caruncular in Group VE were significantly greater than Group M and Group C (p<0.05). Mean outer caruncular diameters were greater on Day 3 compared to Day 6 regardless of groups (p<0.05). Mean inner caruncular diameters were greater on Day 3 compared to Day 6 regardless of groups (p<0.05). There was no differences in terms of mean inner caruncular diameters between groups (p>0.05). In conclusion, it was found that prepartum administration of Vitamin E, Selenium and Melatonin had no significant effects on the completion time of postpartum uterine involution on Awassi ewes.
