Effect of Coloured light environments on some behavioral patterns, physiological aspects and performance of broilers

The present investigation was done to study the effect of different coloured light environments on some behavioural patterns, physiological aspects and performance. Thus 64 one day old chicks were divided randomly in to four groups exposed to different coloured light environments [yellow, red, blue and white]. The results revealed that: 1- the red, blue and white coloured environments were the suitable media for the proper performance during the first 3 weeks of the rearing period, respectively. 2- The yellow colour environment was the most comfortable medium during the last four weeks of the rearing period of chickens that reflected positively on the ethology, physiology and performance of the birds
