摘　　要：【目的】研究乌拉尔甘草(Glycyrrhiza uralensis)茎叶全混合日粮,对巴楚白山羊育肥效果和血液性状的影响。【方法】选取18只健康巴楚白山羊[平均体重(18.13±3.21)kg],均等分为3个组,进行为期2个月的饲喂试验。3个处理分别为:(1)对照组(Ctrl),50%混合精料+50%稻草;(2)试验Ⅰ组(G25),50%混合精料+25%稻草+25%甘草茎叶;(3)试验Ⅱ组(G50),50%混合精料+50%甘草茎叶。【结果】干物质采食量及表观消化率在各处理组间无显著差异(P>0.05),G25组的中性洗涤纤维表观消化率比其他组有所提高,与G50组之间的差异达到显著水平(P<0.05)。山羊瘤胃液的p H值、总挥发性脂肪酸浓度以及乙酸/丙酸比在各处理之间均无明显变化,但与Ctrl组相比G25和G50组山羊瘤胃液氨态氮浓度都有所降低。各试验处理组间各项血液性状和平均日增重差异不显著(P>0.05),G25组的饲料报酬高于Ctrl和G50组。【结论】乌拉尔甘草茎叶适宜比例,替代全混合日粮中部分粗饲料有提高动物饲喂效果的趋势,25%左右替代比例饲喂效果较好,建议在生产中应用。【Objective】This study is conducted to determine effects of total mixed ration（ TMR） of the aerial parts of Ural licorice（ Glycyrrhiza uralensis） on fattening and blood character of Bachu goat.【Method】18 Bachu goats（ body weight of（ 18. 13 ± 3. 21） kg） were evenly allocated into 3 groups,and the feeding trial lasted two months. Three treatments included： 1） control group（ Ctrl）,50% mixed concentrate ＋ 50% rice straw; 2） test group 1（ G25）,50% mixed concentrate ＋ 25% rice straw ＋ 25% the aerial parts of Ural licorice; 3） test group 2（ G50）,50% mixed concentrate ＋ 50% the aerial parts of Ural licorice.【Result】The result showed that no significant differences were observed in the dry matter intake and the apparent digestibility of all test groups（ P〈0. 05）,and the apparent digestibility of neutral detergent fiber of G25 was increased than other groups,and compared with G50 group（ P〈0. 05）,the p H,total volatile fatty acids concentration and the acetate / propionate ratio of rumen fluid was not affected by feeding the aerial parts of Ural licorice,but the ammonia- N concentration was decreased in G25 and G50 groups than that in Ctrl group. In the final stage trials,no significant differences were found in the blood characteristics and the averaged daily gain between all the groups tested（ P〉0. 05）,and the feed conversion efficiency of G25 was increased compared with Ctrl and G50 groups.【Conclusion】In conclusion,the use aerial parts of Ural licorice appropriate alternative forage in the total mixed ration improves animal feeding effect,and the feeding effect of substitution of about 25% is better,which is recommended to be applied in the future production.
