Data of "Poor repeatability of cortisol responses to adrenocorticotropic hormone (ACTH) in beef heifers: is the ACTH challenge a suitable measure for stress research in cattle?"

Data for article "Poor repeatability of cortisol responses to adrenocorticotropic hormone (ACTH) in beef heifers: is the ACTH challenge a suitable measure for stress research in cattle?" Dataset of 64 crossbred beef heifers which were subjected to three ACTH challenges. Both experimental independent variables (animal id, horn status, replicate, time of day of the ACTH challenge, ACTH challenge number) and post-ACTH salivary cortisol concentrations (at the seven sampling timepoints and area under the curve values) are presented.本数据集配套论文为《肉牛青年母牛促肾上腺皮质激素（adrenocorticotropic hormone, ACTH）刺激后皮质醇应答重复性差：ACTH激发试验是否适用于牛应激研究？》，收录了64头杂交肉牛青年母牛的实验数据。所有受试个体均接受了三次ACTH激发试验。数据集涵盖两类实验数据：其一为实验自变量，包括个体编号、角状态、重复次数、ACTH激发试验的当日时间、ACTH激发试验序号；其二为ACTH刺激后唾液皮质醇浓度数据，包含7个采样时间点的检测值以及曲线下面积（area under the curve, AUC）数值。
