Peripheral leukocyte heat shock proteins (HSP: HSP90, HSP70, and HSP23) from broiler chickens and turkey poults were induced by in vitro and in vivo high temperature exposure. Heat conditioning, via a daily 1 h exposure to 41 C, enhanced in vitro HSP expression in leukocytes from chickens heat-conditioned for 1 to 2 wk, and a similar response was found in turkey poults with 3 wk of heat conditioning causing the greatest HSP expression. In vivo heat exposure trials caused maximization of HSP expression after 1 wk of daily heat conditioning exposures in broilers, but no additional enhancement was seen in chickens heat conditioned for 2 wk. Enhancement in HSP expression was evident for periods up to 4 wk after termination of the daily heat conditioning episodes.
通过体外和体内高温暴露诱导肉鸡和小火鸡外周血白细胞热休克蛋白（HSP：HSP90、HSP70和HSP23）。通过每天1小时暴露于41℃进行热适应，增强了热适应1至2周的鸡白细胞的体外HSP表达，在小火鸡中也发现了类似的反应，3周的热适应导致最大的HSP表达。在肉鸡中，体内热暴露试验在每天热适应暴露1周后导致HSP表达最大化，但在热适应2周的鸡中未观察到额外增强。在每日热适应期结束后的4周内，HSP表达增强明显。
