Anadolu Merinoslarında İrisin Hormon Yanıtı Üzerine Bazı Fizyolojik Parametrelerin Etkisi

Öz

Bu çalışmanın amacı, Anadolu Merinosu koyunlarında irisin hormon yanıtı üzerinde vücut kondüsyon skoru (VKS), laktasyon, gebelik, yaş ve cinsiyetin etkisinin incelenmesidir. Çalışmaya dahil edilen tüm gruplarda yer alan Anadolu Merinosu koyunları vücut kondüsyon skorlarına (VKS<2,VKS=3-3.5,VKS≥4) göre 3 gruba ayrılmıştır. 1.grup gebeliğin ilk dönemindeki koyunlar (ilk gebeliğin 100. gününde) (n=30), 2.grup erken laktasyon döneminde bulunan koyunlar (n = 30),3.grup farklı yaşta bulunan <2 (genç) (n=30), 2-8 (ergin) (n=30), 8> (yaşlı) (n=30), erkek ve dişi koyunlar (n=180) olmak üzere toplam 240 hayvan oluşturdu. Koyunlardan sabah yemlemesi öncesi vena jugularis'ten kan örnekleri alındı. Kan serumu örneklerinde ELİSA yöntemiyle irisin hormon düzeyleri belirlendi. Çalışma sonucunda laktasyon ve gebelik döneminde ortalama serum irisin hormon düzeyleri en düşük VKS<2 grubunda, en yüksek ise VKS ≥4 gruplarında bulunan koyunlarda saptanmıştır. Aynı şekilde farklı yaş ve cinsiyet gruplarında ise en düşük ortalama serum irisin hormon düzeyleri VKS<2 grubunda bulunan genç kuzu ve toklularda iken, en yüksek düzey ise VKS ≥4 grubunda yaşlı koyun ve koçlarda tespit edilmiştir. Sonuç olarak, VKS değişimine bağlı olarak farklı yaş, cinsiyet, gebelik ve laktasyon dönemlerinin serum irisin hormonu düzeyi üzerine etkisi olduğu belirlenmiştir (P<0,05).

Effect of Some Physiological Parameters on The Hormone Response of İrisin in Anatolian Merino Sheep

Öz

The aim of this study was to examine the effect of body condition score (BCS), lactation, pregnancy, age and gender on the hormone response of irisin in Anatolian Merino sheep. Anatolian Merino sheep in all groups included in the study were divided into 3 groups according to their body condition scores (BCS<2, BCS=3-3.5, BCS≥4). 1st group, sheep in the first period of pregnancy (100 of the first pregnancy (n=30), 2nd group, of sheep found in early lactation period (n = 30), 3rd group consisted of <2 (young) (n=30), 2-8 (adult) (n=30), 8> (old) (n=30) ewe (n = 90) and rams (n = 90) were of different ages consisted of a total of 240 animals. Blood samples were taken from vena jugularis before the morning feeding of the sheep. Hormone levels of the iris were determined by ELISA method in blood serum samples. As a result of the study, mean serum irisin hormone levels during lactation and pregnancy were found in sheep in the lowest BCS<2 Group and the highest BCS ≥4 groups. In the same way, in different age and gender groups, the lowest mean serum irisin hormone levels were found in young lambs and Toks in the BCS<2 group, while the highest level was found in older sheep and Rams in the BCS ≥4 group. As a result, it was determined that different age, gender, pregnancy and lactation periods had an effect on serum irisin hormone level depending on BCS change (P<0.05).
