The effect of the heat exposure on the plasma levels of insulin, glucagon and 11-hydroxycorti-costeroids (11-OHCS) in calves was studied by employing an arginine tolerance test. Those hormone levels increased transiently following an arginine injection. The response in plasma insulin due to arginine was inhibited by the heat exposure. Meanwhile, glucagon and 11-OHCS responses due to arginine were enhanced by the heat exposure.
