Effects of thermal manipulation during broiler chicken embryonic days 12–18 on body temperature (T^b) and mRNA expressions of Hsp108, Hsp70, Hsp47 and Hsf-3 in muscle, heart and brain tissues during subsequent thermal challenge (TC) were investigated. Fertile chicken eggs were divided randomly into four groups (n = 375): eggs in the control group were maintained at 37.8 °C and 56% (RH). Eggs in TM₁ group were subjected to TM at 39 °C for 9 h during ED 12–18. Eggs in the TM₂ and TM₃ groups were subjected to the same protocol of TM₁ except for increasing the period of exposure to 12 h and 18 h, respectively. During TC (43 °C for 6 h) at days 10 and 28, T^b of TM chicks was significantly lower compared to controls. Furthermore, significant changes in mRNA expressions of Hsp108, Hsp70 and Hsp47 in muscle, heart and brain tissues were observed.
