Abstract:
Low intensity red (Lambda =633 nm) light was used on hatching poultry and quail eggs to determine its influence on embryonic and post-embryonic development. Certain regimens of hatching egg irradiation (p=0.1 mW/cm2, t=60 c) significantly increased hatching rates (3.66-4.05%, p<0.001) and decreased chick mortality (1.25-3.23%, p<0.05) for layer and broiler chickens compared to untreated controls (using industrial poultry farm conditions). Laser irradiation of hatching egg increased chick blood hemoglobin, changed (increased in embryo and decreased in postembryo period) liver peroxide levels and activated cytochrome P-450 enzyme system without adversely affecting liver energy metabolism.
