Cocks were exposed to 1 or 2 h at 24 degrees C; blood samples were taken before and immediately after treatment and for a period of 20 h thereafter. 2. Heat caused a significant decrease in leucocyte counts, an increase in corticosterone concentration in plasma and an increase of ascorbic acid in plasma and in leucocytes. 3.

将公鸡置于24摄氏度环境中1或2小时；在处理前、处理后即刻以及此后20小时内采集血样。2. 热导致白细胞计数显著下降、血浆中皮质酮浓度升高以及血浆和白细胞中抗坏血酸增加。3. 这四项指标可用于指示应激反应，且测量过程不会对动物造成伤害。
