Abstract: A method for reducing the negative effect of heat acclimatization for the hatching of a poultry hatching egg is provided. A special light source is used as an ambient light to hatch the poultry hatching egg. The special light source is light-emitting diode (LED) monochromatic blue light with a light intensity of 20 lux to 50 lux and a wavelength of about 450 nm, such that the light can reduce the negative effect of heat acclimatization at a hatching stage of the poultry hatching egg. The method can reduce the levels of oxidation products such as malondialdehyde (MDA) and corticosterone in a chicken embryo during heat acclimatization at the hatching stage of the poultry hatching egg and increase the expression levels of antioxidase and heat shock protein (HSP) genes, and the special light source reduces the metabolic heat production of the chicken embryo.
