摘要：

Exposure of laying hens to an acute heat stress period (38 degrees C) produced a decrease (P less than or equal to 0.05) in blood plasma magnesium compared with pre-heat stress (23 degrees C) levels. Blood plasma glucose, alkaline phosphatase, total protein, uric acid and creatinine were not changed (P greater than or equal to 0.05) by exposure to 38 degrees C compared with the first 23 degrees C exposure. Inorganic phosphorus, calcium, potassium and sodium levels were not affected by acute heat-stress exposure or carbon dioxide addition. These results suggest that acute heat stress had no dramatic effect on plasma enzymes, metabolites and electrolytes of laying hens.
