This study was conducted on quail to investigate the effects of some organic acids on egg qualities characters, enteric ecosystem and reproductive performance. One hundred eightybirds were reared from 1 day to 42 days of age, distributed to 3 treatments, (three replicates, 20 birds / replicate) . 1<sup>ST</sup> treatment (control) reared on standard ration, 2<sup>nd</sup> treatment reared on standard ration supplemented with Lactic acid (2.5 mg / kg ration), 3<sup>rd</sup>treatment reared on standard ration supplemented with Citric acid (2.5 mg / kg ration). Statistical analysis of data showed that the addition of Organic acid improves significantly (P ≤ 0.05) egg weight, albumen weight, yolk weight, height of albumen, high of yolk, yolk diameter, egg length, shape index, weight of first egg, age oflaying 50% egg laying intensity, weight of male reproductive system and length of oviduct as compared with control treatment . No significantly effects in yolk index, egg width, shell weight, shell thickness and internal shell membranes. Significant decrease in <em>Salmonella</em> and <em>E.Coli</em>. Significant increase in Lactobacillus content and significant increase in Lymphocyte % in male and females quail , in Hetrophils and Esinophils in females treated with Organic acid . Improved H/L ratio in Organic acid treatment as compared with control, andsignificant decreased (P ≤ 0.05) in Coagulation timeand Cholesterol concentration in 2<sup>nd</sup> and 3<sup>rd</sup> treatment; In conclusion, organic acids improved the enteric ecosystem , egg quality and reproductive performances .
