High ambient temperature could result in numerous physiological and metabolic perturbations on broilers chicken with consequently adversely impact in broilers performance and immune response. Though the environmental control technique have been frequently useful for reduce the negative impact of heat stress in poultry performance, other alternative have been studied. Lately, the nutritional manipulation is also used for reducing the heat stress, once the most part of thermobalance components of broiler (heat production, evaporative and nonevaporative heat dissipation routes) could be manipulated though the diet. Specially, the eletrolitic balance have fundamental importance in physiological stress mechanism and for this way should be considered as a tool in control of this metabolic dysfunction in birds.
