“…In addition to estrogen's role in stimulating the VLDLR gene important in the growth and development of ovarian follicles [25], the Forkhead box12 gene, under the influence of the estrogen receptor, contributes to the basic regulation of egg production, growth and development of ovarian follicles, and ovulation events [ 26]. In order to avoid triglyceride breakdown during translocation to the follicle, the liver overexpresses VTG-II [27] and increases the production of ApoVLDL-II [28], an LPL inhibitor [29]. After sexual maturation, estrogen plays a key role in activating yolk precursors by increasing ApoVLDL-II and VTG-II gene expression [30,31].…”

This study aimed to investigate the impact of implementing Glycetin by injection on the productive features of local Iraqi chickens. 100 female hens and 20 roosters from a local Iraqi chicken population, at age 26 weeks. The sample was divided into three groups, in addition to a control group. Each experimental group had 25 female hens, with the same procedure being performed for each individual hen, and 20 roosters, which were reared separately for the purpose of artificial insemination. The avian specimens were housed in separate enclosures, and the experimental conditions were allocated as follows: the initial condition (Control Group) did not receive any injections, whereas conditions T2, T3, and T4 were administered with varying doses of Glycetin at concentrations of 5, 10, and 15 milligrams per kilogram of body weight, respectively. The results showed improve significant (P<0.05) many aspects such as egg production rate, cumulative egg count, egg mass, egg weight, and feed conversion ratio.
