Light color plays a crucial role in regulating avian reproductive physiology through neuroendocrine mechanisms. The present study evaluated the comparative effects of white, red, blue and green color LED light on egg production, egg quality traits, fertility and hatchability of Japanese quail (Coturnix coturnix japonica) reared under semi-arid climatic conditions. A total of 252 day-old quail chicks were randomly allocated to four treatment groups with three replicates of 12 birds each. Birds were exposed to white (control), red, blue or green LED light at a constant intensity of 20 lux for 15 weeks. Egg production and egg quality parameters were recorded from 7 to 15 weeks of age. Fertility and hatchability were calculated using standard formulas. Data were analyzed using one-way ANOVA followed by Duncan’s multiple range test. The Result revealed that the Red LED light significantly enhanced egg production, fertility and hatchability (P < 0.01), while green LED light significantly improved egg weight, shell weight and shell thickness. Blue light resulted in comparatively lower reproductive performance across most parameters. These findings demonstrate that spectral manipulation using LED systems can be effectively utilized to optimize reproductive efficiency in Japanese quail under semi-arid production conditions.
