A refreshing, rehydrating and stress relieving mentholated oral solution for administration via drinking water that reduces mortality and productivity losses in animals suffering from heat stress due to high ambient temperatures and a high relative humidity, especially in poultry. Heat stress in these animals may lead to general distress, reduced feed intake and body weight, increased feed conversion rates, increased carcass fat content, decreased fertility rates, low-quality semen, decreased egg size and production, reduced
egg-shell quality, increased amount of dejections, increased susceptibility to illness, increased number of culled animals and increased mortility rates.
