Ten 16-week-old Friesian x Hereford heifer calves were split into experimental and control groups. Experimental animals were given an implant of oestradiol-17 beta in the ear whilst controls were given blank implants. They were killed 14 days later. After implantation the experimental group had consistently greater (P less than 0.01) plasma concentrations of oestradiol-17 beta than the control group. After death, sebaceous gland volume in the perineal region was greater (P less than 0.01) in the experimental than in the control group, whereas sebaceous gland volume in the neck was smaller (P less than 0.01). Sweat gland volume in the perineal region was greater (P less than 0.01) in the experimental than in the control group. There was no difference between groups in the volume of sweat glands in the neck.
十头16周龄的弗里斯兰×赫里福德小母牛犊被分成实验组和对照组。给实验组动物在耳部植入17β-雌二醇，而给对照组植入空白植入物。14天后将它们宰杀。植入后，实验组的血浆17β-雌二醇浓度始终高于对照组（P<0.01）。死后，实验组会阴区皮脂腺体积大于对照组（P<0.01），而颈部皮脂腺体积小于对照组（P<0.01）。实验组会阴区汗腺体积大于对照组（P<0.01）。两组颈部汗腺体积无差异。
