Effect of light color on some of performance indices of hybrid cup 500-broilers

Abstract

This study was conducted at private poultry station to determine the effect of light color on the most important performance indices of broilers. A total of 559 broiler chicks of Hybrid Cup 500, one-day-old were distributed randomly into three groups at a rate of 188 birds in the first group (the control, G1) and 188 birds in the second group (G2) and 183 birds in the third group (G3), each group included six replicates, at a rate of 30-32 birds per replicate. The chicks per group were raised, fattened, housed and managed under the same procedures in independent different sections of closed pen until the age of 49 days. Three different light color lights (white, control, WLG), green (GLG) and Yellow (YLG) were applied from day one to the end of fattening period (49 days). Results showed that the application of green or yellow lights on broilers did not significantly affect the mortality rate, average live weight and average feed consumption compared with white light. However, application of green light on the broilers has led to a significant reduction (4.4%, p<0.05) in the feed conversion rate for the whole period of fattening compared with white light.
