A doctoral dissertation entitled “(Glycine Injection and its Impact on Sexual Maturity, Reproductive Performance, and Gender of the Iraqi Local Chicken)” was defended at the College of Agricultural Engineering Sciences at the University of Baghdad by the student Noha Abdul Kareem Kazem Al-Mousawi from the Department of Animal Production.
The study aimed to determine the extent of the impact of injecting chickens with different levels of plant estrogen hormone (claystein) on sexual maturity, and its effect on reproductive performance, gender ratios, and its relationship to its blood levels with the apparent sexual changes of chicks after hatching. It also examined its effect on the level of aromatase enzyme and determined the relationship between aromatase and estrogen.
The researcher recommended conducting larger, more comprehensive studies to understand the mechanisms of the role of estrogen hormone in sexual differentiation and studying its effects during genetic development. Other suggested approaches included treating chickens with claystein through methods such as egg injection, addition to feed, or water.
Congratulations to the student, and we extend our wishes for her continued success and prosperity.
