摘　　要：本试验以3只健康的卡拉库尔羊为瘤胃液供体,采集瘤胃液进行体外发酵培养,试验设计为基础日粮中分别添加不同来源样组:对照组(G0)、10%胀果甘草粗提物组(G1)、10%刺果甘草粗提物组(G2)、10%刚果甘草粗提物(G3)、10%甘草原样(G4);分别添加不同水平甘草提取物组:0%组(Z0)、0.5%组(Z1)、1%组(Z2)、3%组(Z3)、5%组(Z4)、7%组(Z5),研究其对瘤胃发酵参数:pH、挥发性脂肪酸(乙酸、丙酸、丁酸)、产气量、氨态氮浓度(NH3-N)的影响。结果显示,本试验添加的G1、G2、G3、G4组在一定程度上均可以降低瘤胃产气量和乙酸产量;添加不同剂量的甘草粗提取物时,Z3组的添加剂量使瘤胃pH在正常范围,同时对产气量无显著影响,乙酸/丙酸比值为最低。The ruminal fermentation was done by in vitro culture techniques,rumen fluid from three Karakul sheep with installed permanent rumen fistula.Experimental design based diets were supplemented with different sources of Licorice extract sample groups： control group（G0）,10% crude extracts of Glycyrrhiza inflate group（G1）,10% crude extract of Glycyrrhiza pallidiflora group（G2）, 10% crude extracts of Glycyrrhiza glabra group（G3）,10% Licorice sample（G4）;different levels of Licorice extract group of 0% respectively（Z0）,0.5% group（Z1）,1% group（Z2）,3% group（Z3）,5% group（Z4）,7% group（Z5）,the rumen fermentation parameters were studied such as pH,volatile fatty acids（acetic acid,propionic acid,butyric acid）,gas production,ammonia concentration（NH 3-N）.The results showed that G1,G2,G3,G4 groups reduced rumen gas production and acetic production.Adding different doses of Licorice crude extract,rumen pH value of Z3 group was in the normal range,and had no significant influence on gas production,but acetic/propionic ratio of that was the lowest.
