To investigate the effects of chlorogenic acid‐enriched extract (CGAE) from Eucommia ulmoides Oliver leaf on growth performance and quality and oxidative status of meat in pigs fed diets containing fresh or oxidized corn oil, a total of 180 barrows (initial body weight: 81.6 ± 2.08 kg) were randomly allocated into 6 diet treatments (5 replicate pens per treatment and 6 barrows per pen) in a 2 × 3 factorial design with corn oil (fresh or oxidized corn oil at 5% inclusion of diet) and CGAE (0, 500 or 1,000 mg/kg of diet containing fresh or oxidized corn oil) as main factors. The experiment lasted for 6 weeks. Dietary oxidized oil reduced average daily gain (ADG, p < .05) and average daily feed intake (ADFI, p < .01) of pigs and pH 24 ( p < .05), total antioxidant capacity (T‐AOC, p < .01), glutathione peroxidase (GPx, p < .05) and sarcoplasmic reticulum Ca 2+ ‐ATPase (SERCA, p < .05) activities in meat and increased drip loss ( p < .01), cooking loss ( p < .05), malondialdehyde ( p < .01) and carbonyl ( p < .01) contents and mRNA expression of superoxide dismutase 1 ( SOD1 , p < .05) in meat. Dietary CGAE supplementation at 1,000 mg/kg increased ( p < .05) ADG and ADFI of pigs and pH 24 , T‐AOC, T‐SOD, GPx and SERCA activities and mRNA expression of SOD1 in meat and reduced ( p < .05) drip loss, cooking loss, carbonyl and malondialdehyde contents in meat. No interaction effects between oxidized corn oil and CGAE were found in pigs. Overall, dietary CGAE supplementation at 1,000 mg/kg improved growth performance and quality and oxidative status of meat in pigs subjected or not to oxidative stress induced by dietary oxidized oil.
