摘要
Twenty-eight adult macaques were divided into five groups for differenttreatments.Of these five groups,groups 1 to 3 were exposed to heat once dailyfor 10d until the rectal temperature (RT) rose to 40℃,40.8℃ and 41.6℃,respectively.The other two groups (groups 4 and 5) were exposed to heat twicedaily and every other day,respectively,until the RT of both groups reached41.6℃.The method of heat exposure to obtain the required RT was to keep themacaques in a hot chamber (Td 41℃,Tw 38℃).Before and after theacclimatization period,the macaques were given a standard high temperature testin the same environment as the heat acclimatization (HA) period until the RTrose to 41.6℃.The results revealed that the animals in groups 3 to 5 whose RTin HA increased to 41.6℃ showed a significant HA effect by prolonging the dura-tion of exposure (P【0.05～0.001) and decreasing the RT (1.14～1.83℃),especiallyin the daily exposed group.Therefore,one of the most effective ways for devel-oping full acclimatization in macaques is to expose to heat once daily for 10duntil the RT rises to 41.6℃.
