Abstract
Broiler chickens have limited capacities to sustain high temperatures. However, thermal manipulation (TM) during embryogenesis has been shown to lower their body temperature at hatch and to improve thermotolerance until market age (Piestun et al., 2008). This thermotolerance acquisition could partly be due to changes in sensible heat loss, but also in metabolic rate, especially in energy and protein metabolisms of birds. The aim of this study was to evaluate the long-lasting effects of TM during embryogenesis, when coupled or not with a heat challenge at slaughter age (d 34), on plasma metabolites and hormones, cell signaling and the expression of genes involved in muscle metabolism.
