In the first stage, when environment temperature arrived to 37.5℃, Ta of A and B dairy barn was 35.5 and 36.7℃, respectively. And at the same time Tr was higher than 39.5℃. Specially, the high yield dairy in A barn raised to 41 ℃ at 22:00 and RR was 90/min, the RR of low yield dairy was 65/min at this time. mTs was 37.6℃ at 15:00. In the third stage, Ta of the barn was higher than outside when outside Ta was lower than 27.6℃. When the ambient temperature was lower than 28℃, the Tr of low yield dairy was between 38.5 and 39℃; if the Ta was down to 24℃, Tr of high yield dairy was lower than 39℃.
