摘　　要：本试验旨在研究饲粮中添加沙棘黄酮对广西小麻鸭生长性能、肉品质、血清生化指标及免疫器官指数的影响。试验选取4周龄广西小麻鸭(雌鸭)120只,随机分为4组,每组6个重复,每个重复5只。对照组饲喂基础饲粮,3个试验组分别饲喂在基础饲粮基础上添加0.05%、0.10%、0.15%沙棘黄酮的试验饲粮。试验包括预试期和正试期,其中预试期7 d,正试期70 d。结果显示:1)饲粮中添加0.05%~0.15%的沙棘黄酮对广西小麻鸭的末重、平均日增重、平均日采食量、料重比均无显著影响(P>0.05)。2)与对照组相比,饲粮中添加0.05%和0.10%沙棘黄酮显著降低胸肌的滴水损失率(P<0.05),添加0.10%沙棘黄酮显著降低腿肌的pH 45 min(P<0.05)。3)试验第35天,与对照组相比,0.05%组血清谷胱甘肽过氧化物酶(GSH-Px)活性显著提高(P<0.05),0.10%组血清丙二醛(MDA)含量显著降低(P<0.05),0.15%组血清总胆固醇(TC)和低密度脂蛋白胆固醇(LDL-L)含量显著降低(P<0.05),0.05%组、0.01%组和0.15%组血清高密度脂蛋白胆固醇(HDL-L)含量与总超氧化物歧化酶(T-SOD)、铜锌超氧化物歧化酶(CuZn-SOD)活性均显著提高(P<0.05);试验第70天,与对照组相比,0.10%组和0.15%组血清T-SOD活性均显著提高(P<0.05),0.15%组血清甘油三酯(TG)和LDL-L含量显著降低(P<0.05),0.05%组、0.01%组和0.15%组血清CuZn-SOD活性均显著提高(P<0.05),0.05%组、0.01%组和0.15%组血清MDA含量均显著降低(P<0.05)。4)饲粮中添加0.05%沙棘黄酮可显著提高广西小麻鸭的胸腺指数和脾脏指数(P<0.05)。试验第35天,与对照组相比,0.05%组血清免疫球蛋白G(IgG)含量显著提高(P<0.05),0.05%组、0.01%组和0.15%组血清免疫球蛋白M(IgM)含量均显著提高(P<0.05),0.10%组和0.15%组血清免疫球蛋白A(IgA)含量均显著降低(P<0.05);试验第70天,与对照组相比,0.05%组血清IgA和IgM含量显著提高(P<0.05),0.10%组和0.15%组血清IgG含量均显著降低(P<0.05)。综上所述,The aim of this experiment was to study the effects of dietary supplementation of sea buckthorn flavonoids on the growth performance,meat quality,serum biochemical indexes and immune organ indexes of Guangxi small hemp ducks.One hundred and twenty 4-week-old Guangxi small hemp ducks(female)were randomly divided into 4 groups with 6 replicates per group and 5 ducks per replicate.The ducks in control group were fed a basal diet,and those in the three experimental groups were fed the basal diet supplemented with 0.05%,0.10%and 0.15%of sea buckthorn flavonoids,respectively.The trial consisted of a pre-test period and a test period,where the pre-test period was 7 days and the test period was 70 days.The results showed as follows:1)diet supplemented with 0.05%to 0.15%sea buckthorn flavonoids had no significant effects on the final body weight,average daily gain(ADG),average daily feed intake(ADFI)and feed-to-gain ratio(F/G)of Guangxi small hemp ducks(P>0.05).2)Compared with control group,diet supplemented with 0.05%and 0.10%sea buckthorn flavonoids significantly reduced the drip loss rate of chest muscle(P<0.05),and diet supplemented with 0.10%sea buckthorn flavonoids significantly reduced the pH 45 min of leg muscle(P<0.05).3)On the day 35 of the test,compared with the control group,the serum glutathione peroxidase(GSH-Px)activity was significantly increased in the 0.05%group(P<0.05),the serum malondialdehyde(MDA)content was significantly decreased in the 0.10%group(P<0.05),the serum total cholesterol(TC)and low-density lipoprotein cholesterol(LDL-C)contents were significantly decreased in the 0.15%group(P<0.05),and the serum high-density lipoprotein cholesterol(HDL-L)content,total superoxide dismutase(T-SOD)and copper-zinc superoxide dismutase(CuZn-SOD)activities were significantly increased in the 0.05%,0.01%and 0.15%groups(P<0.05);on the day 70 of the test,compared with the control group,the serum T-SOD activity was significantly increased in the 0.10%and 0.15%groups(P<0.05),the serum triglycerides(TG)and LDL-L con
