摘要: Abstract Though previous study indicated that the 580 nm-yellow-LED-light showed an stimulating effect on growth of chickens, low luminous efficiency yellow LED light cannot reflect advantage energy saving. In present study, cool white chips and have been combined to fabricate white × yellow mixed light, with enhanced efficiency. A total 300 newly hatched chickens were reared under various light. The results had “double-edged sword” effects bird's body weight, bone development, adipose deposition, temperature, depending variations in ratios component. Low ratio (Low group) inhibited whereas medium high (Medium High groups) promoted compared (White group). progressive change component gave rise consistent changes weight over entire experiment. Moreover, a positive relationship was observed between feed conversion ratio. group-treated birds greater relative abdominal than Medium (P = 0.048), (P = 0.044). We found improved by enhancing skeletal development (R2 = 0.5023, P = 0.0001) deposition (R2 = 0.6012, P = 0.0001). Birds Medium, Yellow groups attained significantly higher surface temperatures White group (P = 0.010). suggest application level can be used successfully improve productive performance broilers.
