摘　　要：[目的]探讨不同秸秆发酵剂厌氧消化单一木薯杆或混合基质的效果。[方法]选择活力99生酵剂(1.20×1010cfu/g)、产酶益生素(2.0×1010cfu/g)、粗饲料降解剂(2.0×108cfu/g)3种复合有益菌进行试验。试验组在木薯杆原料中添加微生物发酵剂,对照组只添加同量的水,厌氧消化基质3个月,测定其粗蛋白、粗纤维、粗脂肪、钙、磷、氨基酸含量。[结果]厌氧消化效果与秸秆发酵剂的种类有关,也与基质种类有关。粗饲料降解剂可以显著提高单一木薯杆的粗脂肪、磷、天冬氨酸、丝氨酸、丙氨酸含量;3种发酵剂对木薯杆混合和单一基质粗蛋白、粗纤维含量均无明显影响;粗饲料降解剂处理木薯杆对改善木薯杆饲料品质有一定效果,产酶益生素、活力99没有效果。[结论]该研究可为木薯秆制作生物饲料新技术筛选出适宜的发酵剂。[ Objective ] To discuss the effects of anaerobic digestion of different straw starters on single cassava-rod or mixed matrix. [ Meth- od] Three types of starters, including active 99 fermentation agent（ 1.20× 10^l0 cfu/g）, enzyme-producing probiotics（2.0 × 10^10 cftt/g） , and roughage degradation agent（2.0× 10^8 cfu/g）, were selected. The cassava rod materials were added with microbial starter in the experimental group, but the same amount of water in the control group, after three-month anaerobic digestion of the matrix, the contents of crude protein, crude fiber, crude fat, calcium, phosphorus, and amino acid were determined. [ Result] The anaerobic digestion results were closely related to the type of starters and matrix. The roughage degradation agent can significantly improve the content of fat, phosphorus, aspartate, serine and alanine of single cassava-rod ; Three kinds of starters had no significant effect on the contents of crude protein and crude fiber in single cassava-rod and mixed matrix ; the roughage degradation agent had certain effect on improving the quality of cassava-rod feed, while enzyme-producing probiotics and energy 99 did not have. [ Conclusion] The study selected the optimum starter for preparing bio-feeds with cassava rod.
