摘要
为研究苜蓿和红车轴草黄酮提取物对绵羊生长性能、血液生化指标、激素和抗氧化性的影响,选取36只1.5月龄杜湖杂交公羔羊,随机分成3组,每组12只,对照组饲喂基础日粮,苜蓿组饲喂添加苜蓿黄酮提取物20mg/kg,红车轴草组添加红车轴草黄酮提取物15mg/kg。预饲期10d,正试期60d,分别对各组绵羊生长性能、血液生化指标、激素和抗氧化性指标进行测量。结果表明,添加苜蓿和红车轴草黄酮提取物提高了血清中生长激素(GH)、胰岛素生长因子1(IGF-1)和三碘甲腺原氨酸(T3)含量;显著提高肉羊的日增质量(P<0.05),降低料重比;显著降低血清中甘油三酯(TG)和总胆固醇(TC)含量(P<0.05);提高了谷胱甘肽过氧化物酶(GSH-Px)、超氧化物歧化酶(SOD)和过氧化氢酶(CAT)活性,降低丙二醛(MDA)的含量,增强肉羊的抗氧化性能。综上所述,试验中苜蓿和红车轴草黄酮提取物添加量可以调节绵羊血液抗氧化性能、激素和部分生化指标,提高肉羊的日增质量。
In order to investigate the effect of flavonoids from Medicago sativa L. and Trifolium pratense L. on growth performance, blood biochemical indexes and antioxidant properties of sheep, the hybridization male lambs between Dorper sheep and Hu sheep were selected in this research. Thirty six sheeps were divided into three groups randomly. The control group was fed on basal diet,Medicago sativa L. group I fed basal diet adding extracts of alfalfa flavonoids（20 mg/kg）, Trifoliurn pratense L. group Ⅱ fed basal diet adding extracts of Trifoliurn pratense L. flavonoids （15 mg/kg）. Preliminary feeding period was 10 days,this experiment lasted 60 days. Growth per- formance,blood biochemical indexes and antioxidation characteristics of sheep were determined. The results showed that flavonoids from Medicago sativa L. and Trifoliurn increased the content of GH, IGF-1 and T3 of serum,increased average day gain significantly（P〈0.05）, decreased feed conversion ratio,triglyceride and total cholesterol significantly（P〈0.05）,increased the GSH-Px, SOD and CAT activity, decreased MDA content, and improved antioxidation characteristics of sheep. This experiment shows that the flavonoids from Medicago sativa L. and Trifoliurn pratense L. could improved blood antioxidant properties, hormone and some biochemical indexes of sheep,it is benefit for sheep average day gain.
