Effects of Monochromatic Blue Light on Reducing the Adverse Impact of Induced Cyclic Chronic Heat Stress during the Thermal Manipulation of Broiler Embryos.

The results suggest that monochromatic blue light can reduce the content of MDA and corticosterone of broiler embryos in heat stress and increase the relative expression of SOD and CAT genes. Moreover, the monochromatic blue light may reduce the metabolic heat production of broilers during the embryonic stage, thus reducing the damage of broilers due to heat stress during the embryonic heat acclimation stage.
