Abstract: The present experiment has been executed to find out the impact of different colors of light-emitting diode (LED) on growth performance and meat quality traits of Pekin ducks (Anas platyrhynchos). For this purpose, a total of 360 day-old mixed sex ducklings were allocated to six lightproof rooms separated from each other by wooden chip board. These six rooms were equipped with six colored LED viz. white light (WL), blue light (BL), red light (RL), green light (GL) and yellow light (YL) and incandescent light bulb (IL, 60 Watt) as a control. Each room was divided into six replicates with ten ducks in each replicate. At the end of wk 6, when data were pooled, the body weight (BW), BW gain (BWG) and feed intake (FI) were positively influenced by RL whereas YL showed poor performance (P<0.05). The RL and BL responded significantly to influence feed conversion ratio (FCR). The high pH and red color of duck meat were noticed in BL while low pH and light red color were observed in GL. The meat pH and color were correlated with each other and these attributes were improved in GL. It can be concluded that growth performance of ducks can be improved by using red and blue LED whereas meat quality traits can be improved in ducks by using green LED.
