| 摘 要： | 试验旨在研究以枯草芽孢杆菌、乳酸菌和酵母菌复合菌剂发酵的玉米秸秆对肉羊生长性能、营养物质消化率及甲烷排放的影响。选用30只健康杜泊×小尾寒羊F1代公羔为试验动物，随机分成2组，对照组饲喂未发酵的玉米秸秆，试验组以发酵玉米秸秆替代50%的未发酵玉米秸秆，精粗比45：55。结果表明：复合微生物发酵秸秆能够显著提高肉羊平均日增重及营养物质消化率（P<0.05）；通过“开放式”呼吸测热装置测定甲烷排放量，试验组肉羊每天甲烷排放量比对照组降低21.5%（P<0.05），甲烷能降低21.6%（P<0.05）。以上结果说明，采用复合微生物菌剂发酵玉米秸秆能够显著改善秸秆品质；饲喂发酵玉米秸秆可提高肉羊生长性能及营养物质消化率，并能降低肉羊甲烷排放量，减少甲烷能损失。 |

| Abstract: | The objective of this experiment was to study the effects of dietary supplement of fermented corn straw (fermented by bacillus subtilis, lactic acid bacteria and saccharomycetes) on production performance, nutrients digestibility, and methane emission for mutton sheep. 30 ram lambs (Dorper × Small tailed han sheep, F1) were randomly allotted to two dietary treatments supplemented with 0 (control group) and 27.5% fermented corn straw(experimental group), forage-to-concentrate ratio was 45:55.The results indicated that feeding fermented corn straw could significantly increase the ADG and nutrients digestibility of sheep; the methane emission of experimental group decreased 21.5% compared with control group by using respiration calorimetry unit. In conclusion, microbial fermentation could improve straw quality, and feeding this fermented corn straw could enhance the production performance and nutrients digestibility of mutton sheep, and significantly decrease the methane emission and methane energy. |
