Spexin (SPX, NPQ), a novel neuropeptide composed of 14 amino acid residues, is evolutionarily conserved among different species. Spexin has been suggested to have pleiotropic functions in mammals. However, reports on spexin in birds are limited.

Young geese were subject to a two-phase short-to-long (group A) or a three-phase (long-short-long; group B) photoperiod program February through October. Egg-laying was induced to start similarly in both groups in May, increased to a peak level in July, and then decreased gradually through to October.

- The study focused on how artificial lighting impacts the breeding cycle of the Yangzhou goose, revealing that longer light exposure (up to 12 hours) boosts testis development and testosterone production.
- Testis and hormone activity peaked two months after the light increase but declined significantly after five months, showing a clear relationship between light duration and reproductive function.
- The research found that reproductive stimulation is linked to changes in specific hormones and genes in both the hypothalamus and pituitary gland, indicating a complex interaction governing breeding activity in these birds.
