Abstract

A poultry raising system includes a poultry house and facilities attached to the poultry house. The facilities include lighting facilities irradiating poultry with light; and the lighting facilities include a semiconductor light source, for irradiation with light having peak wavelength in the range of 550 to 650 nm emitted from the semiconductor light source. The light in this wavelength range has positive influence on sexual maturation, appetite, need for sleep and condition of internal organs. Light of shorter peak wavelength includes ultraviolet rays that cause stress on the poultry and attract insects. Light of longer wavelength includes infrared rays that increase temperature of the poultry and of the poultry house. It is possible to emit light having peak wavelength in a specific range effective to growth and fattening. Because of high electricity-to-light conversion efficiency, high economic efficiency can be attained, and CO₂ emission can be reduced. Risk of shattering of a globe by abrupt cooling can be reduced, and temperature increase in the poultry house can be prevented. Longer life reduces danger, labor and cost of exchange. Thus, meat and egg yield can be increased and economical efficiency can be improved.
