Abstract

Apelin is an important adipokine hormone that is released from adipose tissue, which is considered as the energy store of the body, which plays a role in many physiological processes in the body, as well as cardiovascular, immune functions and energy, nutrients and fluid metabolism. In this study, it was aimed to determine the effect of lactation, pregnancy and gender on apelin hormone levels in blood serums belonging to different races of ewe. In the present study, the hormone levels of the pregnant, non-pregnant ewe and rams of the Akkaraman Kangal and Morkaraman races were thin, with different body condition scores ( 0.05). In terms of apelin, gender and body condition score, race and gender, and body condition score interactions were found to be significant.

Highlights

Apelin is an important adipokine hormone that is released from adipose tissue, which is considered as the energy store of the body, which plays a role in many physiological processes in the body, as well as cardiovascular, immune functions and energy, nutrients and fluid metabolism
At the end of the research, when the apelin level of the coaches was examined according to the races and body condition score (Table 2), it was determined that there was a bodyscore difference according to the races, while it was found to be important in the apelin-related interaction between race and body score (Table 3)
In the study conducted on the ewe, it was found that the apelin level in the lactation and pregnancy period was similar in terms of body condition score (Table 3 and 4), but it was determined that there was a difference between races

Summary

Introduction

Apelin is an important adipokine hormone that is released from adipose tissue, which is considered as the energy store of the body, which plays a role in many physiological processes in the body, as well as cardiovascular, immune functions and energy, nutrients and fluid metabolism. It was aimed to determine the effect of lactation, pregnancy and gender on apelin hormone levels in blood serums belonging to different races of ewe. Brown adipose tissue (BAT) has numerous large mitochondria in its cytoplasm (Symonds 2013). UCP1 is only present in small amounts in the fetus and in ewe and humans In neonatal lambs, it is activated with endocrine stimulating factors during delivery only at the beginning of respiration and to provide protection against severe hypothermia (Symonds et al 2003). Apelin hormone secreted from adipose tissue is a member of the hormone-cytokine family, which was discovered recently, isolated from the bovine gastric juice, originates from preproapelin and has a 77-amino acid precursor (Tatemoto et al 2001)
