Resumo

The quail for being an alternative species will be able to supply a new market niche due to its fast growth, high laying rate, low feed intake, in addition to the increase of the acceptance of its products by the consumer. A growing interest in raising the stocking rates in the cages as an alternative to increase the performance of the stock is noticed; although studies demonstrate that high densities can result into unfavorable environment to the birds welfare with alterations in the performance of the flocks and as a stressing factor being able to alter the production and profitability of the flock. At high stocking rates, the birds become predisposed to aggressiveness reactions, presenting cannibalism behavior, besides the combination of factors such as pH, temperature, ventilation and humidity deficiency which create environmental conditions favorable for certain benign bacteria which utilize uric acid of the manure through their enzymatic complexes and produce ammonia, causing stress to birds and which can cause damages to performance with significant economic losses to the producer.  The experiment with 112-day duration was conducted with the objective of evaluating the inclusion of acidulants in the Japanese quails drinking water and verifying the effect on the stocking rate in cages. A completely randomized design with four treatments (2 stocking rates of quails x 2 a
