Abstract
Due to high environmental temperatures and climate change,heat stress is a severe concern for poultry health and production,increasing the propensity for food insecurity.With climate change causing higher temperatures and erratic weather patterns in recent years,poultry are increasingly vulnerable to this environmental stressor.To mitigate heat stress,nutritional,genetic,and managerial strategies have been implemented with some success.How-ever,these strategies did not adequately and sustainably reduce the heat stress.Therefore,it is crucial to take proac-tive measures to mitigate the effects of heat stress on poultry,ensuring optimal production and promoting poultry well-being.Embryonic thermal manipulation(TM)involves manipulating the embryonic environment's temperature to enhance broilers'thermotolerance and growth performance.One of the most significant benefits of this approach is its cost-effectiveness and saving time associated with traditional management practices.Given its numerous advan-tages,embryonicTM is a promising strategy for enhancing broiler production and profitability in the poultry industry.TM increases the standard incubation temperature in the mid or late embryonic stage to induce epigenetic thermal adaption and embryonic metabolism.Therefore,this review aims to summarize the available literature and scientific evidence of the beneficial effect of pre-hatch thermal manipulation on broiler health and performance.
