The tolerance of chickens to acute heat stress, evaluated by the time required to reach the critical body temperature (Tr) of 44.5 degrees C, was markedly enhanced as the period of fasting was extended. 2. Fasting reduced the rates of heat-induced changes in blood acid-base and electrolyte status. 3. Changes in Tr were correlated with changes in blood pH, pCO2, [Cl-] and [Pi] but not with changes in [Na+] or [K+]. 4. Blood acid-base and electrolyte status were related to Tr rather than time of exposure to heat stress.

通过达到44.5摄氏度临界体温（Tr）所需时间评估，随着禁食期延长，鸡对急性热应激的耐受性显著增强。2. 禁食降低了热诱导的血液酸碱和电解质状态变化速率。3. Tr的变化与血液pH、pCO2、[Cl-]和[Pi]的变化相关，但与[Na+]或[K+]的变化无关。4. 血液酸碱和电解质状态与Tr相关，而非与热应激暴露时间相关。
