| 摘 要： | 通过玉米秸发酵试验及半体内法 ,评价了复合产乳酸菌 (植物乳杆菌 保加利亚乳杆菌 粪尿链球菌 嗜酸乳杆菌 )、酶制剂 (纤维素酶 淀粉酶 糖化酶 )、液体发酵剂 (益生菌 )单独或联合应用对玉米秸组成成分及瘤胃有效降解率的影响。结果表明 ,从整个发酵期来看 ,高剂量固体发酵剂组 (每吨秸杆添加复合产乳酸菌 2 0 g 纤维素酶 10 0 g 淀粉酶 30 0 g 糖化酶 30 0 g)、高剂量液体发酵剂组 (每吨秸杆添加益生菌 5 0 0 m L )、中性洗涤纤维 (NDF)含量略低于对照组 (P <0 .0 5 ) ;高剂量的固体发酵剂和液体发酵剂明显提高了玉米秸快速降解的干物质 (DM) (P <0 .0 5 )、NDF成分 (P <0 .0 1) ,显著降低了慢降解的 DM、NDF成分 (P <0 .0 1) ;从有效降解率来看 ,高剂量液体发酵剂组的DM有效降解率明显高于对照组及纤维素酶组 (P <0 .0 5 ) ,NDF有效降解率则比其他各组均有明显提高 (P <0 .0 5 )。

| Abstract: | A fermentation trial was conducted and three fistulated young bulls were used to evaluate the effects of a lactic-acid-producing(Lactobac Lactobacillus bulgarius Pediococuus cerevisiae Str. Faecium Lactobac acid philus) inoculant, an enzyme preparation (cellulose enzyme amylase glucoarmylase) and liquid ferment treatment(probiotics)on silage fermentation, composition, and ruminal degradation when they were applied alone or combined. Results indicated that the content of NDF in groups treated with solid ferment (lactic-acid-producing 20 g cellulose enzyme 100 g amylase 300 g glucoarmylase 300 g/t corn straw) and liquid ferment(efficient microorganism 500 mL/t corn straw)(both added at high levels)was slightly lower than that in control group(P<0.05).Analysis of variance of the degradation parameters of DM and NDF generated by a nonlinear regression model indicated that the treatments of corm straw with solid ferment and liquid ferment(both added at high levels)increased quickly degradable DM and NDF fractions(P<0.05),reduced slowly degradable DM and NDF fractions significantly(P<0.01).The liquid ferment also resulted in higher rates of ruminal DM, NDF degradation as compared with control and other treatments(P<0.05).The biological mechanisms associated with the beneficial results of liquid ferment addition are not understood yet. |
