Exposure of laying hens to an acute heat stress period (38 degrees C) produced a decrease (P < or = 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 > or = 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.
与热应激前（23摄氏度）水平相比，蛋鸡暴露于急性热应激期（38摄氏度）会导致血浆镁含量降低（P≤0.05）。与首次23摄氏度暴露相比，暴露于38摄氏度时，血浆葡萄糖、碱性磷酸酶、总蛋白、尿酸和肌酐没有变化（P≥0.05）。无机磷、钙、钾和钠水平不受急性热应激暴露或添加二氧化碳的影响。这些结果表明，急性热应激对蛋鸡的血浆酶、代谢物和电解质没有显著影响。
