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.

Abstract: A method and system for monitoring the egg-laying performance of caged laying-hens at laying-hen positions are provided. A plurality of coops are disposed side by side, a conveyor belt is disposed below the plurality of coops, and a machine-vision inspection device having a CCD camera and a lighting device is provided on an output end of the conveyor belt. Eggs laid by the hens fall onto the conveyor belt from the bottom of the coops. After all eggs are laid, the conveyor belt is activated to convey the eggs to the machine-vision inspection device, and the CCD camera is triggered to capture an image of a surface of the conveyor belt carrying the eggs.
