Quail housing and diet significantly impact egg yield and quality. This study assessed the impact of diets and housing arrangements on Japanese quail's egg production, egg index, and quality. In two trials, birds were reared in cages and on the floor with a commercial layer diet (CLD), and an experimental diet (ED) for 32 weeks. Compared to floor-reared birds, cage birds achieved 50% egg production and sexual maturity first. With dietary effects, the CLD diet showed similar results. Furthermore, their feed efficiency, hen house egg production (HHEP), and hen day egg production (HDEP) were significantly higher in cage birds that consumed CLD. Bird livability was unaffected by the housing system, while birds fed CLD had longer lifespans. The housing system had no discernible effects on egg dry matter (DM), crude protein (CP), crude fat (CF), or ash percentage. Nevertheless, the egg albumen's DM, CP, ash%, yolk's DM, CP, and CF were greater in the birds fed CLD. Barring shell thickness, weight, and Haugh unit, birds raised in cages exhibited higher egg exterior index values. Besides the yolk ratio, yolk index, and albumen weight ratio, birds given CLD exhibited enhanced egg interior quality. Ultimately, the most optimal egg production performance, improved egg quality, and prolonged lifespan of Japanese quail were obtained with cage raising and feeding practices utilizing CLD.
