Abstract

The study aimed to investigate the effect of light source on growth performance and physiological response of broilers. A total number of one hundred and ninety-two unsexed seven-day old; Cobb broiler chicks were used in this study. Chicks were allocated into two treatment groups. Each treatment consisted of twelve replicates eight birds each. Birds in treatment 1 were exposed to yellow-reddish light produced from 60-watt incandescent lamps, while those in treatment 2 were subjected to white light by using 26 watt saving lamps. The light intensity for all experimental birds were 5 lux at the level of a bird till the end of experiment. Results showed that, using 26 watt saving lamps significantly increased body weight and body weight gain at 28, 35 and 42 days of age, feed consumption at 42 days of age and improved feed conversion ratio from 21-28 and 7-42 days of age. Moreover, using saving lamps significantly increased glucose, HDL and uric acid concentrations and significantly reduced all of creatinine, triglyceride and VLDL. It could be concluded that the using saving lamps as lighting source is more beneficial than the yellow-reddish light produced from 60-watt incandescent lamps
