Heat stress has been reported to induce hepatic oxidative stress and alter lipid metabolism and fat deposition in broilers. Chitosan oligosaccharides (COSs), a natural oligosaccharide, has anti-oxidant, anti-inflammatory, and lipid-lowering effects. This study is conducted to evaluate dietary COS supplementation on hepatic anti-oxidant capacity, inflammatory response, and lipid metabolism in heat-stressed broilers. The results indicate that heat-stress-induced poor ( p < 0.05) growth performance and higher ( p < 0.05) abdominal adiposity are alleviated by COS supplementation. Heat stress increases ( p < 0.05) serum AST and ATL activity, serum and liver MDA, TG, TC, and LDL-C levels, and the expression of hepatic IL-1β , IL-6 , SREBP-1c , ACC , and FAS , while it decreases ( p < 0.05) serum SOD and CAT activity, liver GSH-Px and SOD activity, and the expression of hepatic Nrf2 , GPX1 , IL-10 , MTTP , PPARα , and CPT1. Nevertheless, COS supplementation decreases ( p < 0.05) serum AST and ATL activity, serum and liver MDA, TG, TC, and LDL-C levels, and the expression of hepatic IL-1β , IL-6 , SREBP-1c , ACC , and FAS , while it increases ( p < 0.05) serum SOD and CAT activity, liver GSH-Px activity, and the expression of hepatic Nrf2 , CAT , IL-10 , LPL , MTTP , PPARα , and CPT1. In conclusion, COS could alleviate heat-stress-induced lipid metabolism disorders by enhancing hepatic anti-oxidant and anti-inflammatory capacity.
