摘　　要：为评价不同添加水平甘草粉对育肥羊生长性能、养分表观消化率与肉品质的影响,试验将180只育肥期小尾寒羊,随机分4组,各组3个重复,每个重复15只。各组添加甘草粉水平分别是0(对照组)、15%(试验1组)、30%(试验2组)、45%(试验3组),试验为期30 d。试验结果发现:(1)试验2组平均日增重和平均日采食量最高,料重比最低(P <0.05)。(2)与对照组相比,各试验组干物质及钙消化率显著提高(P <0.05),试验2组粗蛋白质、粗脂肪消化率显著提高(P <0.05)。(3)与对照组相比,各试验组蒸煮损失及剪切力显著降低(P <0.05),试验2组的滴水损失显著降低(P <0.05)。结论 :甘草可以提高育肥羊的生长性能、养分表观消化率,同时促进肉品质的改善,在本试验条件下建议甘草粉适宜添加水平为30%。The study aims to evaluate the effects of different levels of licorice powder on the growth performance,apparent digestibility of nutrients,and meat quality of fattening sheep.180 fattening small tailed Han sheep were selected for the experiment and divide into 4 groups,including 3 repetitions with 15 experimental animals in each repetitionrandomly.The levels of licorice powder added to each group were 0(control group),15%(experimental group 1),30%(experimental group 2),and 45%(experimental group 3),respectively,with an experimental period of 30 days.The research results found that:(1)Experiment 2 had the highest average daily weight gain and average daily feed intake,and the lowest feed to gain ratio(P<0.05).(2)Compared with the control group,the dry matter and calcium digestibility of each experimental group were significantly improved(P<0.05),and the crude protein and crude fat digestibility of experimental group 2 were significantly improved(P<0.05).(3)Compared with the control group,the cooking loss and shear force of each experimental group were significantly reduced(P<0.05),and the drip loss of experimental group 2 was significantly reduced(P<0.05).Conclusion:Licorice can improve the growth performance and apparent digestibility of nutrients of fattening sheep,while promoting the improvement of meat quality,Under the conditions of this experiment,the recommended appropriate level of addition is 30%.
