乳酸菌和纤维素酶对早籼稻秸秆青贮饲料品质的试验

为了开发利用南方丰富的稻草秸秆资源,满足奶水牛生产的需要,在稻草中添加复合乳酸菌与复合纤维素酶的方法青贮,采用不同的复合乳酸菌与复合纤维素酶添加水平,试验设对照组、试验1组、试验2组和试验3组进行处理,常温条件下青贮35d后开封进行青贮饲料品质评定。结果表明:试验各组青贮饲料中DM和ADL含量无显著变化(P0.05),而其它指标均有显著变化(P0.05)。CP含量随复合乳酸菌制剂和酶制剂添加量的增加而增大,其中试验Ⅲ组比对照组高8.41%;NDF和ADF含量随乳酸菌制剂和纤维素酶制剂添加量的增加而下降,试验Ⅲ较对照组低10.92%和0.48%。试验结果表明乳酸菌制剂和纤维素酶制剂的添加可以使青贮稻草饲料品质得到明显改善。

Experiment of lactobacillus and cellulase on the quality of early indica rice stover silage

In order to develop the use of the South abundant straw resources to meet the needs of buffalo production in the rice straw and lactic acid bacteria added composite method of silage cellulose compound,a compound with different lactic acid bacteria and cellulase complex level,the control test set group,group Ⅰ,Ⅱ and Ⅲ,and test group are processed under normal temperature after silage 35 d Kaifeng for silage quality evaluation.The results showed that:Test each group silage DM and ADL showed no significant change (P>0.05),while others were statistically significant change (P<0.05).CP levels of lactobacillus with complex and enzyme preparation increases the amount of which group Ⅲ than the control group 8.41%;NDF and ADF content increased with lactobacillus and cellulose enzyme preparation increased the amount of drop tests than Ⅲ control group 10.92% and 0.48%.The results showed that lactic acid bacteria and cellulase enzymes can add the straw feed silage quality was improved significantly.
