Japanese quail was studied for a period of six weeks. A total of 800 day old, quail chicks were randomly divided into eight treatment groups (T1 to T8), with four replicates of 25 chicks in each. The experimental groups consisted of T1-Control: Basal diet (standard Japanese quail ration without Se supplementation), T2-Basal diet + 0.2 ppm inorganic Se, T3-Basal diet + 0.5 ppm inorganic Se, T4-Basal diet + 0.2 ppm organic Se, T5- Basal diet + 0.5 ppm organic Se, T6-Basal diet + 0.1 ppm nano Se, T7- Basal diet + 0.25 ppm nano Se and T8-Basal diet + 0.25 ppm organic Se + 0.25 ppm nano Se. Dietary supplementation with 0.5ppm organic Se resulted in significantly higher body weight and body weight gain, better feed efficiency and per cent livability than other treatment groups in Japanese quail. The study indicated that organic Se supplementation at 0.5ppm level, significantly improved production performance of Japanese quail.en-USVeterinary SciencePoultry ScienceArticle
