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 degrees C and 56% (RH). Eggs in TM1 group were subjected to TM at 39 degrees 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 degrees 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. (C) 2015 Elsevier Ltd. All rights reserved.
