Abstract
An experiment was conducted to evaluate the effects of supplementing drinking water with isomolar (0.067 mol/l) KCl or NaCl on mass gain, food and water consumption, rectal temperature, and plasma concentrations of aldosterone, Na+, and K+ in broiler chickens reared in thermoneutral and cycling heat stressing environments. Heat stress decreased (P≤0.05) mass gain, food consumption, and plasma concentrations of Na+ and K+, while increases (P≤0.05) in plasma concentrations of aldosterone, rectal temperature, and water consumption were observed. Drinking water supplemented with either KCl or NaCl increased (P≤0.05) broiler mass gain and water consumption, but had no effect (P>0.1) on the other variables evaluated. The results of this study indicate that broiler chickens in a heat stress environment are under osmotic stress and supplementing drinking water with 0.067 mol/1 KCl or NaCl does not lessen this stress.
