The present study was undertaken to assess the effect of supplementation of organic acids on Nutrient metabolizability trial and economics production of 300 Japanese quail divided into 5 treatment groups and each of 4 replicates with 15 birds in each replicate. The groups were T0- Control group, T1- T0 +0.20 % Acetic acid, T2- T0 +0.20 % Butyric acid, T3- T0 +0.20 % Propionic acid and T4 - T0 +0.20 % (Acetic acid, Butyric acid and Propionic acid). Metabolic trial of five days duration was conducted on 8 birds from each treatment at the end of experimental trial to study the dry matter digestibility and N- retention. The economics of production of Japanese quails was also calculated at the end of the experimental period. It is concluded that 0.2 % acetic acid is economically beneficial and also improve the retention of nutrient.
