Effect of different light intensities and colors on growth performance and reproductive characteristics in Japanese quails

Light is one of the most important environmental factors in quail farming, as it has a significant impact on production efficiency and reproductive characteristics. The purpose this study was to determine effect different light intensities colors performance Japanese quails. For first experiment, 200 quails were divided into five treatment groups, each with four replicates (10 birds each). control exposed intensity 20 lux, while other groups 10 15 25 30 lux. experiment lasted for 6 weeks. Weight gain dressing percentage higher that received lux than (p < 0.05), however, feed intake, conversion ratio, relative organs weights not affected by > 0.05). length oviduct lower 0.05) those In second 200-day-old chicks treatments included group compact fluorescent White light, while, Red LED (630 nanometers), (490 Blue (220 Green (550 nanometers). 8 Body weight gain, FCR, percentage, length, number ovarian follicles improved lights Birds had egg weight, egg-shell thickness, yolk index, albumen, conclusion, perform growth when they are intensities, well red light.
