Abstract:

Light information is one of the most important environmental factors in nature. It regulates the physiological functions of the organism through the animal's visual system and the circadian circadian clock system. Birds are light-sensitive animals, and their photoreceptors and diurnal rhythms have a different photoreceptors and circadian rhythms on the retina and pineal glands. They receive light information (light wavelength, light period and light intensity) of the external environment through the light receptors. The different light information processing into a specific biological signal, thus affecting the body's growth and development, production performance and immune function. The authors describe the effects of different light information,such as light cycle, light intensity and light wavelength on the enhancement or inhibition of immune function in broilers, and focus on the control of different light wavelengths (light color) on the immune function mediated by melatonin using its receptor pathway and non-receptor pathway (antioxidant) in broilers. The purpose of this paper is to provide the theoretical basis for the rational use of light information in the process of modern broiler breeding.
