Photoperiod as a neuroendocrine regulator: A review on pineal-melatonin signaling and physiological plasticity in poultry
Day Length as a Hormone Controller: How Pineal Melatonin Signals Affect Body Changes in Poultry
AI simplified
Abstract
Photoperiod influences neuroendocrine function in poultry through the pineal-melatonin axis.
- The pineal gland converts light signals into melatonin secretion, regulating biological rhythms.
- Melatonin is associated with the regulation of reproduction, growth, metabolism, immune function, and stress response.
- Core clock genes and various hormonal axes interact with melatonin, linking environmental cues to physiological changes.
- Photoperiod manipulation may enhance energy allocation and feed efficiency in poultry.
- Melatonin's effects include potential roles in nutrigenomic regulation and epigenetic changes.
- Controlled lighting can improve egg production, meat quality, and overall poultry welfare.
