In order to evaluate the effects of chlorine levels for Japanese quails in the growing phase and its effects on the production phase, 384 quail day old were used distributed in a completely randomized design with six treatments and eight replicates of eight birds. Chlorine levels were: 0.07, 0.12, 0.17, 0.22, 0.27 and 0.32%. The variables studied in the growth phase were: feed intake (g/bird), weight gain (g/bird), feed conversion (g/g), water consumption (mL/bird/day), relative water consumption/feed intake, excreta moisture (%), digestibility of dry matter (%), nitrogen (%), gross energy (%), apparent metabolizable energy (kcal/kg DM) and corrected for apparent nitrogen balance (kcal/kg DM). According to the results the statistical analysis showed no significant effect on feed intake, weight gain, consumption ratio of water / feed intake, excreta moisture, feed conversion, water intake, digestibility of dry matter (CDMS), nitrogen (CDN) and gross energy (GEDC) and values of apparent metabolizable energy (AME) and apparent nitrogen corrected (AMEn) of feed. Although this test showed that chlorine levels received by the quails in the growing phase did not significantly affect the performance of quails. Considering the results, it can be recommended diets for Japanese quails in the growing phase containing chlorine levels up to 0.32%.
