Protective impacts of mitochondria enhancers against thermal stress in poultry

Heat stress (HS) is still the essential environmental agent influencing the poultry industry. Research on HS in poultry has progressively acquired growing interest because of increased attention to cli-mate alteration. Poultry can survive at certain zone of environmental temperatures, so it could be considered homoeothermic. In poultry, the normal body tempera-ture is essential to enhance the internal environment for growth, which is achieved by normal environmental temperature. Recently, many studies have revealed that HS could cause mitochondrial dysfunction in broilers by inducing redox dysfunction, increasing uncoupling protein, boosting lipid and protein oxidation, and oxidative stress. Moreover, HS diminished the energy suppliers supported by mitochondria activity. A novel strategy for combating the negative influences of HS via boosting the mitochondria function through enrichment of the diets with mitochondria enhancers was also described in this review. Finally, the current review highlights the mitochondria dysfunction induced by HS in broilers and attempts to boost mitochondria functionality by enriching mitochondria enhancers to broiler diets.

Automated summary

Heat stress is a crucial factor affecting the poultry industry, and it can induce mitochondrial dysfunction in broilers. Studies have shown that heat stress can disrupt mitochondrial function by causing redox imbalance, increasing uncoupling protein, promoting lipid and protein oxidation, and oxidative stress. To combat the negative effects of heat stress, enriching broiler diets with mitochondria enhancers can boost mitochondrial functionality.
