The goal of this study was to investigate the hair cortisol concentration (HCC) in healthy and ill cows and their newborn calves. A total of 40 cows and their 42 newborn calves were divided into two groups: group 1 consisted of 19 clinically healthy cows and their 20 newborn calves, and group 2 comprised 21 cows that had had a chronic illness in the third trimester of gestation and their 22 newborn calves. A liquid chromatography-tandem mass spectrometry (LC-MS/MS) system was used to measure the HCC in hair samples that were collected from the cows and calves on the day the calves were born. In both groups, the mean HCCs of the calves was significantly higher than that of the cows (group 1, 31,0 vs. 0,6 pg/mg; group 2, 19,4 vs. 0,8 pg/mg; P.
本研究的目的是调查健康和患病奶牛及其新生犊牛的毛发皮质醇浓度(HCC)。总共40头奶牛及其42头新生犊牛被分为两组:第1组由19头临床健康的奶牛及其20头新生犊牛组成,第2组包括21头在妊娠晚期患有慢性疾病的奶牛及其22头新生犊牛。使用液相色谱-串联质谱(LC-MS/MS)系统测量在犊牛出生当天从奶牛和犊牛采集的毛发样本中的HCC。在两组中,犊牛的平均HCC均显著高于奶牛(第1组,31.0 vs. 0.6 pg/mg;第2组,19.4 vs. 0.8 pg/mg;P. (原文此处不完整)
