Used in reproductive physiology research to quantify levels of Gonadotropin Inhibitory Hormone (GnIH) in chicken samples. Enables study of hormonal regulation of reproduction, including suppression of gonadotropin release, control of puberty, and seasonal breeding patterns in poultry. Supports investigations into stress effects on reproductive performance and helps evaluate neuroendocrine pathways in avian species. Commonly applied in academic research, animal science studies, and poultry health monitoring.
