The sebum excretion times (SET) were studied in two breeds of cattle, Bos taurus (SH) and the more heat tolerant B. indicus (GB). Both breeds were maintained in thermoneutral (24 degrees C) and hot (32 degrees C) environments. SET was defined as the time between synthesis and release of sebum on to the skin surface. The SET was 7 days in SH and 6 days in GB animals at 24 degrees C but was a day earlier at 32 degrees C for each breed. The changing SET with environmental temperature was associated with an increased rate of synthesis of sebum with increased body temperature.
对两个品种的牛进行了皮脂分泌时间（SET）的研究，即普通牛（SH）和耐热性更强的瘤牛（GB）。两个品种的牛都饲养在热中性（24摄氏度）和炎热（32摄氏度）环境中。SET被定义为皮脂在皮肤表面合成与释放之间的时间。在24摄氏度时，SH品种牛的SET为7天，GB品种牛的SET为6天，但在32摄氏度时，每个品种的SET都提前了一天。SET随环境温度的变化与体温升高时皮脂合成速率增加有关。
