为研究EM发酵玉米秸秆饲喂陕北白绒山羊效果,试验选择16只健康状况良好的1周岁空怀期陕北白绒山羊，将其随机分成A、B两组，每组8个重复，每个重复1只。试验基础日粮为苜蓿干草200 g+精料补充料200 g。A组饲喂基础日粮+常规玉米秸秆；B组饲喂基础日粮+EM发酵玉米秸秆，试验中A、B两组自由采食秸秆。试验共40d，其中预饲期18 d。结果显示：（1）B组平均干物质采食量显著高于A组（P＜0.05），其中玉米秸秆采食量较A组高22.53%（P＜0.05）；（2）B组DMD、GED和CPD分别较A组高3.65%（P＜0.05）、4.18%（P＜0.05）和8.02%（P＜0.01）；（3）B组平均日增重和饲料转化效率分别为45.45 g和74.19 g/kg，极显著高于A组的22.27 g和39.32 g/kg（P＜0.01）。综上所述，EM发酵的玉米秸秆可以达到开发秸秆粗饲料、减少资源浪费、减少公害、降低生产成本的目的。

To estimate the application value of EMfermented corn straw for Shaanbei White Cashmere goats,a total of 16 oneyearold healthy ewes were divied into 2 group: group A and B, with 8 replicates per group. The basal diet contained 200g alfalfa hay and 200g concentrate supplement. The goats were fed on basal diet + corn straw in group A and basal diet + EMfermented corn straw in group B, respectively,and ewes in both group were accessible to take corn straw. The experiment lasted 40d including 18d adjustment. The results showed: (1) the average DMI of group B was significantly higher than that of group A (P＜0.05), and the corn straw intake was 22.53% higher than that in group A( P＜0.05);(2) the DMD, GED and CPD of group B was 3.65%（P＜0.05), 4.18%（P＜0.05）and 8.02%（P＜0.01）higher than that of group A, respectively. (3) The ADG (45.75g) and FCR(74.19g/Kg) of group B were (P<0.01)22.27g and 39.32g/Kg higher than that in group A,respectively. In conclusion, EMfermented technique could improve the application value of corn straw for Shaanbei white cashmere goat.
