The effect of environmental temperature on the excretion time of sebum in different genotypes of cattle.
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.
