摘　　要：本试验旨在研究饲粮中添加油莎豆或油莎豆粕对妊娠后期母猪营养物质表观消化率、抗氧化能力、脂质代谢及血浆代谢物的影响。试验选取体重、背膘、妊娠期等基本相近的妊娠第70天的“长白×大白”初产母猪70头,随机分为7个组,每组10个重复,每个重复1头猪。对照组(CK组)饲喂玉米-豆粕型基础饲粮,试验组在基础饲粮中分别添加5%(5%TN组)、10%(10%TN组)、15%(15%TN组)的油莎豆及10%(10%TNM组)、15%(15%TNM组)、20%(20%TNM组)的油莎豆粕。试验从母猪妊娠第70天开始到分娩结束。结果表明:1)与CK组相比,5%TN组、10%TN组和10%TNM组的干物质(DM)表观消化率显著提高(P<0.05),各试验组的粗脂肪(EE)表观消化率均显著提高(P<0.05),5%TN组、10%TN组和10%TNM组的中性洗涤纤维(NDF)表观消化率显著提高(P<0.05),5%TN组和10%TN组的钙(Ca)表观消化率显著提高(P<0.05)。2)与CK组相比,各试验组的血清总抗氧化能力(T-AOC)和谷胱甘肽过氧化物酶(GSH-Px)活性均显著提高(P<0.05),15%TN组、10%TNM组和15%TNM组的血清超氧化物歧化酶(SOD)活性显著提高(P<0.05),各试验组的血清活性氧(ROS)含量显著降低(P<0.05),10%TN组、15%TN组、10%TNM组、15%TNM组和20%TNM组的血清丙二醛(MDA)含量显著降低(P<0.05)。3)与CK组相比,20%TNM组的血清脂质运载蛋白2(LCN2)含量显著提高(P<0.05),5%TN组、10%TN组、15%TN组和20%TNM组的血清脂蛋白a(LPa)含量显著降低(P<0.05)。4)与CK组相比,10%TN组5条代谢通路显著富集,分别为嘧啶代谢、赖氨酸生物合成、类固醇生物激素合成、组氨酸代谢和赖氨酸降解;10%TNM组4条代谢通路显著富集,分别为类固醇生物激素合成、嘧啶代谢、花生四烯酸代谢和组氨酸代谢。由此可见,饲粮中添加5%和10%油莎豆均能提高妊娠后期母猪DM、EE、NDF和Ca表观消化率;饲粮中添加油莎豆或油莎豆粕均能显著提高妊娠后期母猪的抗氧化能力;饲粮中添加10%油�This experiment aimed to investigate the effects of dietary tiger nut or tiger nut meal on nutrient apparent digestibility,antioxidant capacity,lipid metabolism and plasma metabolites of sows in late pregnancy.Seventy primiparous pregnant sows with the similar body weight,backfat,and gestational period were selected and randomly divided in to 7 groups with 10 replicates in each group and 1 pig in each replicate.The control group(CK group)was fed a corn-soybean meal type basal diet,and the experiment groups were fed basal diets supplemented with 5%(5%TN group),10%(10%TN group),15%(15%TN group)tiger nut and 10%(10%TNM group),15%(15%TNM group),20%(20%TNM group)tiger nut meal,respectively.The experiment was conducted from the 70th day of gestation to the end of farrowing.The results showed as follows:1)compared with CK group,the dry matter(DM)apparent digestibility of 5%TN,10%TN and 10%TNM groups was significantly increased(P<0.05),the ether extract(DM)apparent digestibility of all experiment groups was significantly increased(P<0.05),the neutral detergent fiber(NDF)apparent digestibility of 5%TN,10%TN and 10%TNM groups was significantly increased(P<0.05),and the calcium apparent digestibility of 5%TN and 10%TN groups was significantly increased(P<0.05).2)Compared with CK group,the serum antioxidant capacity(T-AOC)and glutathione peroxidase(GSH-Px)activity of all experiment groups were significantly increased(P<0.05),the serum superoxide dismutase(SOD)activity of 5%TN,10%TNM,and 15%TNM groups was significantly increased(P<0.05),the serum reactive oxygen species(ROS)content of all experiment groups was significantly decreased(P<0.05),and the serum malondialdehyde(MDA)content of 10%TN,15%TN,10%TNM,15%TNM and 20%TNM groups was significantly decreased(P<0.05).3)Compared with CK group,the serum lipid carrier protein 2(LCN2)content of 20%TNM group was significantly increased(P<0.05),and the serum lipoprotein a(LPa)content of 5%TN,10%TN,15%TN and 20%TNM groups was significantly decreased(P<0.05).4)Compared with CK group,the
