Mr. Entz! Research done by Beker and Teeter (1994) showed that the addition of 0.5% KCl in the water improved broiler performance when the water temperature was 10,0oC ou 26,7oC. When the water temperature was 43,3oC, the KCl addition did not have effect. That is based that tongue neuron sensors react to water temperatures above 25oC.
