The Effect of Birth Type on Serum Irisin Levels in Awassi Lambs

The present study aims to reveal the effects of normal birth and dystocia on serum irisin levels in Awassi lambs. The study material consisted of 20 lambs born from Awassi sheep. Only sheep that had previously given birth normally, had no postnatal problems, and had single births were included to objectively evaluate the parameters under investigation. The newborn lambs were divided into two groups based on the type of birth. Group 1 (n=10) consisted of lambs born from normal births, while Group 2 (n=10) consisted of lambs born from dystocia. Blood samples were collected from the vena jugularis of lambs in both study groups before colostrum intake, after colostrum intake, and on the 15th, 30th, 45th, and 60th days of the postnatal period (a total of six times) and were then centrifuged. Serum irisin levels were assessed using a commercial kit. The obtained data were analyzed using two-way ANOVA. In the intergroup assessment, the serum irisin level in the dystocia group was found to be higher before colostrum intake (P
