Effects of acute heat stress at different ambient temperature on hepatic redox status in broilers.

ABSTRACT: This study aimed to investigate the effects of different acute high ambient temperatures on redox status in liver of broilers. A total of 144 35-day-old Arbor Acres broilers were randomly divided into 4 groups with 6 replicates of 6 birds each and subsequently distributed in different environment chambers for acute heat stress. The temperature of 4 environment chambers were set to 26°C (control), 29°C, 32°C, 35°C for 6 h, respectively. Various indicators were tested to evaluate hepatic redox status. Then, the hallmarks of hepatocellular antioxidant and apoptosis were measured by qRT-PCR and Western Blot. The results showed that with the ambient temperature increase (i) the content of hydrogen peroxide (H₂O₂) and protein carbonyl (PC) in the liver of broilers increased
