| The objective of this study was to investigate the effects of vitamin C and α-lipoic acid dietary supplementations for 42 days on metabolic response of broilers to heat stress during entire feeding period. Whereas negative control birds were kept to 24°C as ambient temperature, heat stressed broilers fed with basal diets (stress positive controls) and supplemented with vitamin C (250 mg/kg/day) or with α-lipoic acid (250 mg/kg/day) were exposed to 34°C for 8 hours every day. Serum biochemical markers, serum lipid profiles, blood gas analysis and acid-base regulation were assessed at the end of the experimental period. Despite the long term heat exposure, serum concentrations of glucose, total proteins, albumin, globulins, lipids (triglycerides, cholesterol and lipoproteins), electrolytes (Na+, K+ and Cl-) and iron as well as serum liver enzyme (AST, ALT, GGT and ALP) activities were not significantly altered compared to the negative controls. By contrast, pancreatic amylase activity was dramatically increased, the uric acid and Mg concentrations were significantly declined and Ca and P concentrations also tended to decrease in birds exposed to heat stress. In parallel, the respiratory rate was markedly accelerated leading to amplification in blood gas exchanges (significant increase in pO |
