摘　　要：文章旨在探究发酵葛藤对贵州黑山羊血清生化指标、生长性能、屠宰性能及肉质性状的影响,试验选取6月龄、生长状况良好、平均体重为(21.46±0.58)kg的贵州黑山羊公羊28只,随机分为4组,分别为对照组、试验Ⅰ组、试验Ⅱ组和试验Ⅲ组,每组7只,对照组饲喂基础日粮,试验Ⅰ、Ⅱ、Ⅲ组分别在基础日粮中添加了5%、10%、15%的发酵葛藤,预饲期7 d,正式期90 d,每间隔30 d,测定试验羊的体重并计算该段时间的采食量,待试验结束后,采集试验羊的血液测定生化指标,同时每组选取3只进行屠宰,测定贵州黑山羊的屠宰性能,采集相应的后腿肌肉组织测定肉质性状。结果表明:试验Ⅰ组采食量高,生长速度快,平均日增重较高达(160.11±1.86)g,且料重比显著低于其他组(P<0.05);试验Ⅰ组的屠宰率和净肉率显著高于其他各组(P<0.05),试验Ⅱ组显著高于试验Ⅲ组(P<0.05),但试验Ⅲ组与对照组无显著差异(P>0.05);肉色和pH值各组之间无显著差异(P>0.05),试验Ⅰ组剪切力和熟肉率最小,显著低于其他组(P<0.05);试验Ⅱ组和试验Ⅲ组之间差异不显著(P>0.05),但显著低于对照组(P<0.05);试验Ⅰ组蛋白质和脂肪含量显著高于对照组(P<0.05);血液生化指标上看,试验Ⅰ组总蛋白和白蛋白含量显著高于对照组(P<0.05),IgG、IgM和IgA含量显著高于对照组(P<0.05)。综上所述,日粮中添加5%的发酵葛藤能显著提升贵州黑山羊的饲喂效果,可以作为最佳的添加比例使用。In order to investigate the effects of fermented kudzu on serum biochemical indexes,growth performance,slaughter performance and meat quality traits of Guizhou black goats,28 Guizhou black goats with an average body weight of(21.46±0.58)kg at the age of 6 months were selected and randomly divided into 4 groups:control group,test groupⅠ,test groupⅡand test groupⅢ.The control group was fed with basic diet,and experimental groupⅠGroupⅡand GroupⅢwere fed with 5%,10%,and 15%fermented kudzu vine,respectively.The pretest period was 7 days,and the formal period was 90 days,at an interval of 30 days.The weight of the experimental sheep was measured and the feed intake during this period was calculated.At the same time,3 goats from each group were selected for slaughter to determine the slaughter performance of Guizhou black goats,and the corresponding hindleg muscle tissue was collected to determine the meat quality characteristics.The results showed that the feed intake of test group i was high,the growth rate was fast,the average daily gain was up to(160.11±1.86)g,the ratio of feed to gain was significantly lower than that of other groups(P<0.05).The siaughter rate and net meat rate in test group i were significantly higher than those in other groups(P<0.05),and those in test groupⅡwere significantly higher than those in test groupⅢ(P<0.05),but there was no significant difference between test groupⅢand control group(P>0.05).There were no significant differences in meat color and pH value among all groups(P>0.05),and the shear force and cooked meat percentage in test groupⅠwere the smallest,which were significantly lower than those in other groups(P<0.05).There was no significant difference between trial groupⅡand trial groupⅢ(P>0.05),but it was significantly lower than that in control group(P<0.05).The contents of protein and fat in test group i were significantly higher than those in control group(P<0.05);in terms of blood biochemical indexes,the contents of total protein and albumin in test g
