Changes in plasma electrolytes, acid-base balance and other physiological parameters of adult female turkeys under conditions of acute hyperthermia.

The effects of acute hyperthermia on certain physiological parameters of turkey hens was studied. It was found that the response of the turkey to hyperthermia is similar to the reported response of the chicken. The birds began panting and the average body temperature increased 0.1 degrees C. as the ambient temperature reached 32 degrees C. The panting or polypnea induced a profound respiratory alkalosis in the turkeys. The acute hyperthermia also caused a significant (P less than 0.05) decrease in plasma levels of sodium, total calcium, magnesium and inorganic phosphorus. The plasma level of potassium was significantly (P less than 0.05) increased.
