【摘要】：为了研究酵母硒、黄芪多糖对半番鸭屠宰性能和血清生化、抗氧化指标的影响,从22日龄健康半番鸭中选出体质量相近的144只,采用单因子试验设计,随机分为4组(3个试验组,1个对照组),对照组饲喂基础饲粮,试验组在基础饲粮中分别添加0.3%酵母硒、300 mg/kg黄芪多糖和二者的复合物(300 mg/kg黄芪多糖+0.3%酵母硒),每组3个重复,每个重复12只。结果显示:除复合剂组半番鸭半净膛率显著高于对照组(P0.05)外,各试验组半番鸭较对照组的屠体率、全净膛率、胸肌率、腿肌率均呈升高趋势(P0.05),而腹脂率和皮脂率均低于对照组(P0.05)。复合剂组血清尿酸含量极显著低于对照组(P0.01),且与黄芪多糖组差异有统计学意义(P0.05);复合剂组血清尿素氮含量显著低于对照组和黄芪多糖组(P0.05);各试验组半番鸭血清乳酸脱氢酶活性均显著低于对照组(P0.05),但各试验组间差异无统计学意义(P0.05);各试验组半番鸭血清白蛋白及球蛋白含量较对照组呈上升趋势(P0.05),而总蛋白含量、白球比、胆固醇含量、谷草转氨酶和碱性磷酸酶活性均呈降低趋势(P0.05)。复合剂组半番鸭血清谷胱甘肽过氧化物酶活性、总抗氧化能力较对照组显著增加(P0.05),且复合剂组血清总抗氧化能力显著高于黄芪多糖组(P0.05);各试验组半番鸭血清超氧化物歧化酶活性较对照组呈增加趋势(P0.05);复合剂组和酵母硒组半番鸭血清丙二醛含量较对照组显著降低(P0.05)。综上所述,在基础饲粮中添加酵母硒、黄芪多糖及其复合剂对半番鸭屠宰性能无明显影响,但在一定程度上可提高半番鸭机体的代谢水平和抗氧化能力,且复合剂的添加效果尤为显著。
[Abstract]:In order to study the effects of yeast selenium and astragalus polysaccharide on slaughtering performance, serum biochemical and antioxidant indexes, 144 healthy muscovy ducks of 22 days of age were selected for single factor design. They were randomly divided into 4 groups (3 experimental groups and 1 control group). The control group was fed with basic diet. The experimental group was fed with 0.3% yeast selenium in the basal diet. 300 mg/kg Astragalus polysaccharides and their complex (300 mg/kg Astragalus polysaccharides 0.3% yeast selenium), each group 3 repeat, each repeat 12 rats. The results showed that the percentage of carcass, total muscovy, pectoralis and leg muscle in the experimental group was higher than that in the control group (P0.05), except that in the compound group was significantly higher than that in the control group (P0.05), the percentage of sternal muscle, pectoral muscle and leg muscle of the experimental group were significantly higher than that of the control group (P0.05). The abdominal fat rate and sebum rate were lower than the control group (P0.05). The serum uric acid content in the compound group was significantly lower than that in the control group (P0.01), and the difference was statistically significant (P0.05), while the serum urea nitrogen content in the compound group was significantly lower than that in the control group and the astragalus polysaccharide group (P0.05). The activity of lactate dehydrogenase in the serum of each experimental group was significantly lower than that of the control group (P0.05), but there was no significant difference among the test groups (P0.05). Compared with the control group, the serum albumin and globulin contents of each experimental group increased (P0.05), while the total protein content, white ball ratio, cholesterol content, glutamic oxaloacetic transaminase and alkaline phosphatase activity decreased (P0.05). The glutathione peroxidase activity and total antioxidant capacity of muscovy duck serum in the compound group were significantly higher than those in the control group (P0.05), and the total antioxidant capacity in the compound group was significantly higher than that in the astragalus polysaccharide group (P0.05). Compared with the control group, the activity of serum superoxide dismutase (SOD) in each experimental group was increased (P0.05), and the malondialdehyde (MDA) content in serum of muscovy duck in the compound group and yeast selenium group was significantly lower than that in the control group (P0.05). To sum up, adding yeast selenium to basic diet, astragalus polysaccharide and its compound had no significant effect on slaughtering performance of muscovy duck, but it could improve metabolism level and antioxidant ability of muscovy duck to some extent. And the effect of adding compound agent is especially remarkable.
