Interactions between three climatic conditions and exogenous adrenocorticotropin (200 IU) or saline on glucocorticoids of plasma were tested in six pregnant Holstein heifers. Animals were under cold (5 C, 30% relative humidity), thermoneutral (18 C, 50% relative humidity), and hot (35 C, and 80% relative humidity) conditions. Effects of treatment, interactions of environment with treatment, and environment with treatment with interval on glucocorticoids of plasma were measured through timed intervals of blood collection at pre- and postintravenous injection of a treatment solution. Adrenocorticotropin elevated corticoid concentrations in plasma, but interactions of environment with treatment and environment by treatment by sampling interval were nil for responses of corticoids in plasma.
在六头怀孕的荷斯坦小母牛中测试了三种气候条件与外源性促肾上腺皮质激素（200国际单位）或生理盐水对血浆糖皮质激素的相互作用。动物处于寒冷（5摄氏度，相对湿度30%）、热中性（18摄氏度，相对湿度50%）和炎热（35摄氏度，相对湿度80%）条件下。通过在静脉注射治疗溶液前后定时采集血液，测量治疗效果、环境与治疗的相互作用以及环境与治疗和采样间隔对血浆糖皮质激素的相互作用。促肾上腺皮质激素升高了血浆中的皮质激素浓度，但环境与治疗的相互作用以及环境与治疗和采样间隔对血浆中皮质激素反应的相互作用不存在。
