摘　　要：试验旨在探讨大蒜秸秆对青山羊血清生化、抗氧化能力、生长性能和养分表观消化率的影响。试验将40只5月龄雄性青山羊按体重相近原则随机分为4组,每组10个重复,每个重复1只羊。对照组饲喂大麦秸秆,试验1组、2组、3组分别用大蒜秸秆替代10%、20%、30%的大麦秸秆。预试期7 d,正式试验期30 d。结果表明:与对照组相比,试验1组、2组、3组平均日增重较对照组提高了17.7%、29.7%、16.5%(P<0.05),试验2组料重比降低了13.1%(P<0.05);试验1组、2组、3组干物质(DM)、粗蛋白(CP)、中性洗涤纤维(NDF)、酸性洗涤纤维(ADF)表观消化率均显著提高(P<0.05);试验1组、2组、3组血清中总蛋白含量分别增加3.7%、4.1%、3.4%(P<0.05),白蛋白含量分别增加6.5%、5.2%、2.3%(P<0.05),球蛋白含量分别增加4.1%、3.5%、3.0%(P<0.05),血清中葡萄糖含量分别降低了7.6%、10.2%、6.4%(P<0.05),甘油三酯含量降低了14.3%、23.8%、21.4%。试验1组、2组、3组血清超氧化物歧化酶(SOD)活性、过氧化氢酶(CAT)活性、总抗氧化能力(T-AOC)显著高于对照组(P<0.05),试验2组、3组血清谷胱甘肽过氧化物酶(GSH-Px)活性显著高于对照组和试验1组(P<0.05),试验1组、2组、3组血清丙二醛(MDA)显著低于对照组(P<0.05)。研究表明,大蒜秸秆替代部分大麦秸秆饲喂青山羊效果良好,替代20%的大麦秸秆效果最佳。The purpose of this experiment was to investigate the effects of garlic straw on the serum biochemistry,antioxidant capacity,growth performance,and nutrient apparent digestibility of Qingshan sheep.Forty 5-month-old male Qingshan sheep were randomly divided into four groups,with 10 replicates per group and one sheep per replicate.The control group was fed with barley straw,and Group 1,Group 2,and Group 3 were fed with garlic straw instead of 10%,20%,and 30%barley straw,respectively.The pre-test period was seven days,and the formal test period was 30 days.The results showed that compared with the control group,the average daily gain of Group 1,Group 2 and Group 3 increased by 17.7%,29.7%,and 16.5%(P<0.05),and the feed to gain ratio of Group 2 decreased by 13.1%(P<0.05).The apparent digestibility of dry matter(DM),crude protein(CP),neutral detergent fiber(NDF),and acid detergent fiber(ADF)in Group 1,Group 2,and Group 3 increased significantly(P<0.05).The total protein content in serum of Group 1,Group 2,and Group 3 increased by 3.7%,4.1%,and 3.4%respectively(P<0.05),the albumin content increased by 6.5%,5.2%,and 2.3%(P<0.05),the globulin content increased by 4.1%,3.5%,and 3.0%(P<0.05),serum glucose content decreased by 7.6%,10.2%,and 6.4%(P<0.05),and the content of triglyceride decreased by 14.3%,23.8%,and 21.4%.The activities of superoxide dismutase(SOD),catalase(CAT),and total antioxidant capacity(T-AOC)in serum were significantly higher than those in control group(P<0.05),the activity of glutathione peroxidase(GSH-Px)in serum was significantly higher than those in control group and Group 1(P<0.05),and the serum malondialdehyde(MDA)in Group 1,Group 2,and Group 3 was significantly lower than those in control group(P<0.05).The study indicates that garlic straw has a good effect on feeding Qingshan sheep instead of part of barley straw,and the best effect is to replace 20%barley straw.
