Interactive Effects of Stocking Density and Light Color on Productive, Physiological Responses of Japanese quail

Abstract

The study was carried out with the aim of assessing interactive effects of stocking density and light color on productive 
performance, egg quality, physiological characteristics and indicators of oxidative stress in laying Japanese quail. Four 
hundred and fifty Japanese quail that were female were randomly allocated in a 3 x 2 factorial design to observe three 
levels of stocking density, two LED colors of light. To measure productive characteristics, egg quality traits, 
hematological and biochemical parameters and oxidative stress indicators were measured during the experimental 
period. The findings revealed that the combination of stocking density and light color had a significant impact on most 
of the traits examined. The low or medium stocking density of treatments with red light tended to have a better 
productive performance, egg production characters, egg quality, and improved physiological and oxidative profiles. 
Conversely, the high stocking density in the white light had the least desirable results, such as reduced productive 
efficiency and unfavorable physiological indications. The productive result was further supported by the 
hematological and biochemical results, and the oxidative stress markers showed better antioxidant status in the more 
favorable treatments. Finally, the relationship between the light color and the stocking density significantly influenced 
the response of laying Japanese quail. Red light and lower or moderate density of the stocking gave the best results in 
terms of production, physiological stability, and oxidative balance. This research demonstrates the relevance of 
integrated environmental management as a viable method of enhancing performance and welfare of intensive quail 
production system.
