Repeat breeder ineklerde tohumlama sonrası yapılan hormonal desteğe, laktasyon sayısı, süt verimi ve sağımda geçen gün süresinin etkisi

Öz:
Amaç: Repeat breeder ineklerde tohumlama sonrası uygulanan hormonal desteğe;laktasyon sayısı, süt verimi ve sağımda geçen gün süresinin etkisinin araştırılmasıdır.Gereç ve Yöntem: Çalışmada; en az bir kez doğum yapmış, seksüel siklusları düzenlive en az 3 kez tohumlandığı halde gebe kalmamış, 169 Holstein ırkı inek kullanıldı.Çalışmaya dahil edilen ineklere PGF2α+ovsynch östrus senkronizasyonu uygulandı. Sabit zamanlı tohumlanan inekler (0. gün) 4 gruba ayrıldı. Birinci gruba (GrupI, Progesteron grubu, n=42) dâhil edilen ineklerin vajinalarına tohumlama sonrası84. saatte progesteron salan intravajinal araç (PRID) yerleştirildi ve 9. günde vajinadan uzaklaştırıldı. İkinci gruba (Grup II, hCG grubu, n=40) dahil edilen ineklere 7.günde hCG kas içi uygulandı. Üçüncü grup (Grup III, Progesteron+hCG grubu, n=45)hayvanlara ise progesteron ve hCG uygulamaları kombine edildi. Dördüncü gruptaki(Grup IV, Kontrol grubu, n=42) hayvanlara herhangi bir uygulama yapılmadı.Bulgular: Tohumlama sonrası 30. gündeki gebe kalma oranları Grup I’de %40,47;Grup II’de %37,50; Grup III’te %44,44 ve Grup IV’te ise %30,95 olarak belirlendi(p>0,05). Laktasyon sayılarına göre Grup I dışındaki gruplarda gebe kalma oranlarında istatistiksel bir farklılık tespit edilmedi (p>0,05). Ancak tüm repeat breederinekler değerlendirildiğinde laktasyon sayısı ≥3 olan hayvanların gebe kalma oranları laktasyon sayısı 1 ve 2 olanlara göre daha düşük bulundu. Ayrıca kontrol grubundaki ineklerde süt verimleri arttıkça gebe kalma oranının düştüğü tespit edildi(p<0,05). Sağımda geçen gün sürelerine göre gruplar arasında istatistiksel bir farklılık tespit edilmedi (p>0,05).Öneri: Repeat breeder ineklerde tohumlama sonrası yapılan hormon uygulamalarında gebe kalma oranı istatistiki olarak artmamakla birlikte; hormonal destek yapılan gruplarda gebelik oranı kontrol grubuna göre daha yüksek bulundu.. Ayrıcarepeat breeder ineklerde laktasyon sayısı ve sağımda geçen gün sürelerinin gebelikoranını etkilemediği ancak süt verimi arttıkça gebelik oranının düştüğü belirlendi.

The effect of lactation number, milk yield and days in milk on hormonal support following insemination in repeat breeder cows

Aim: To investigate the effect of number of lactations, milk yield and days in milk on hormonal support following insemination in repeat breeder cows. Materials and Methods: 169 Holstein cows that gave birth at least once, had regular sexual cycles and did not get pregnant although inseminated at least 3 times were used in the study. PGF2α+ovsynch estrus synchronization protocol was applied to cows included in the study. Fixed time inseminated cows (Day 0) were divided into 4 groups. In the first group (Group I, progesterone group, n=42), progesterone releasing intravaginal device (PRID) was placed in the vagina at the 84th hour and removed from the vagina on the 9th day. hCG was administered intramuscularly to the cows included in the second group (Group II, hCG group, n=40) on day 7. In the third group (Group III, progesterone+hCG group, n=45), progesterone and hCG applications were combined. No application was made to the animals in the fourth group (Group IV, control group, n=42). Results: The conception rate on the 30th day after insemination was determined as 40.47% in Group I; 37.50% in Group II; 44.44% in Group III and 30.95% in Group IV (p>0.05). According to the number of lactations, no statistical difference was found in the conception rates in the groups except Group I (p>0.05). However, when all repeat breeder cows were evaluated, the conception rate of animals with a lactation number of ≥ 3 was found to be lower than those with a lactation number of 1 and 2. In addition, as the milk yield of cows in the control group increased, the conception rate decreased (p<0.05). There was no statistical difference between the groups according to the days in milking (p>0.05). Conclusion: Although the conception rate did not increase statistically in hormone applied cows; it was found higher in hormonal support groups than control group. In addition, it was determined that the number of lactation and the days in milk did not affect the conception rate in repeat breeder cows, but the conception rate decreased as the milk yield increased.
