This study investigated the influence of dietary resveratrol (300 mg/kg) supplementation in sows on the antioxidative status, myofiber characteristic and meat quality of their progeny. Results showed that maternal dietary resveratrol supplementation increased (P < 0.05) the backfat thickness and tended (P = 0.055) to increase the intramuscular fat of finishing pigs. The drip loss and lactic acid level were reduced, and the pH_{24 h} of longissimus thoracis was increased by maternal dietary resveratrol supplementation (P < 0.05). Maternal dietary resveratrol supplementation increased the mRNA and protein expression of MyHC I and decreased the mRNA and protein expression of MyHC IIb in the longissimus thoracis (P < 0.05). The malonaldehyde (MDA) level in longissimus thoracis was reduced and the superoxide dismutase (SOD) activity and SOD2 mRNA expression were increased by maternal dietary resveratrol supplementation (P < 0.05). In conclusion, dietary resveratrol supplementation in sows improves the meat quality of offspring by altering the myofiber characteristic and antioxidative status.

本研究调查了母猪日粮白藜芦醇（300 mg / kg）的添加对其后代的抗氧化状态，肌纤维特性和肉品质的影响。结果表明，母猪日粮中白藜芦醇的添加增加 了背 脂厚度（P <0.05），并趋向于（P = 0.055）增加了肥育猪的肌内脂肪。的滴水损失和乳酸水平分别降低，并且pH _24小时的最长胸外科增加了母亲饮食补充白藜芦醇（P  <0.05）。孕妇膳食补充白藜芦醇可增加MyHC I的mRNA和蛋白表达，并降低MyHC IIb的mRNA和蛋白表达。胸最长肌（P  <0.05）。母体日粮白藜芦醇的添加可降低人经胸中丙二醛（MDA）的水平，并增加超氧化物歧化酶（SOD）活性和SOD2 mRNA的表达（P  <0.05）。总之，母猪日粮中添加白藜芦醇可以通过改变肌纤维特性和抗氧化状态来改善后代的肉质。
