Abstract | The lipid profile assay is considered as good indicators of the physiological state and reproductive performance of livestock. Therefore, this study aimed to evaluate the association of progeny type with the lipid profile on the status of the reproductive hormones in Iraqi Awassi ewes. A total of 200 sexually mature ewes (114 ewes with single progeny and 86 ewes with twin progeny), non-pregnant and non-lactation, aged between 2.5 to 5 years were included in this study. The blood samples were collected and the sera were separated from blood to determine lipid profile assay and reproductive hormones. The result referred to the significant differences (P < 0.05) in cholesterol and sex hormones levels between ewes with single compared to the twin progenies. The strongly positive correlation (P < 0.01) was recorded between ewes with twin progeny with cholesterol (r=0.52, P=0.01), high-density lipoprotein (HDL) (r=0.31, P=0.04), estradiol (r=0.46, P=0.02), and progesterone (r=0.50, P=0.03) respectively. In conclusion, birth progeny type is associated with lipid profile and sex hormones levels in Awassi ewes. The ewes with twin lambs are associated with the highest cholesterol and sex hormones levels than ewes with a single lamb.
