The expression of gonadotropin releasing hormone receptor gene in ovaries and uterus cells of Iraqi and Damascus goat breed

Abstract

Iraqi goats have a major economic role in production of meat, milk and leather as well as it considered a financial source for owners as reproduce twice a year, yet the Damascus goats have great importance than Iraqi goats owing to the number of twin births. The gonadotropin releasing hormone (GnRH) and its receptors have great importance in the reproduction and eugenics. To make a comparison between the Iraqi and Damascus goats in terms of this receptor gene expression in the ovaries and uterus tissue cells, the study was performed, in which used the (∆Ct Using a Reference Gene method) by quintitive -real time PCR technique. Results were found a significant difference (p<0.05), as the gene expression of (GnRH-R) higher in the ovaries and uterus tissue cells in Damascus goats compared with the Iraqi goats. In conclusion; the multiple pregnancies of twins in Damascus goats may be due to an increase gene expression of (GnRH-R) in the ovaries and uterus tissue
