A study was conducted to investigate the effects of nano Zn supplementation on production performance, immune response and carcass characteristicsin Japanese quail broiler. Methods: Synthesis of zinc oxide nano-particles was carried out by chemical method and characterized by standard techniques. Day old Japanese quail chicks (n=240) were randomly allotted in four treatment groups for feeding trial and fed with basal diet and source of zinc viz. for T1 inorganic zinc oxide, for T2, T3 and T4 nano zinc oxide was used at 75%, 50% and 25% levels of BIS recommendation for Zinc. Production parameters, immune response, carcass characteristics and cost economics were studied. Result: Based on the data analysed T3 and T4 showed significantly (P<0.05) improved performance in production parameters like body weight gainand cumulative feed conversion ratio than T1 and T4. HI, titer value and carcass characteristics data also showed similar trend.EnglishArticle
