BackgroundPoultry detect light via photoreceptors in the retina, pineal gland and hypothalamus. The retina regulates behaviors (including feeding) while the hypothalamus controls homeostatic and physiological processes (including reproduction). Because each organ responds differently to wavelengths and intensities, it is possible to adjust lighting programs to specifically promote feeding in pullets and reproduction in adults. This research combines prior lighting work conducted at the University of Guelph and development of a precision broiler breeder feeding system (PBBFS) for broiler breeders at the University of Alberta. The objective of the research is to provide enough light for broiler breeder pullets to maximize access to the PBBFS without impacting sexual maturation and fertile egg and chick production.
