Ph.D. Dissertation at the University of Basrah Explores Genetic Polymorphisms of Leptin and Ghrelin Hormone Receptor Genes
A Ph.D. dissertation at the College of Agriculture, University of Basrah, investigated the genetic polymorphisms of the leptin and ghrelin hormone receptor genes and their association with growth and physiological parameters in Iraqi goat kids fed diets with varying proportions of roughage.
The dissertation, conducted by researcher Murtadha Kareem Mohammed, aimed to examine the physiological traits related to the concentrations of certain metabolic hormones—particularly leptin and ghrelin—as well as selected biochemical parameters in goat kids.
The study involved feeding animals rations containing different proportions of concentrate and roughage (hay), according to the designated dietary ratios, and subsequently identifying the genetic polymorphisms of the targeted genes.
The dissertation concluded with the discovery of two novel genetic variants: one in the ghrelin receptor gene and another in the leptin receptor gene of Iraqi goats.
