摘要

摘要: 试验选用Agaricus blazei和Valvariella volvac两种食用菌对稻草进行不同周期的微贮处理,分别以高压处理和未处理稻草作为处理对照和对照组,通过瘤胃降解试验,研究不同菌种对改善稻草纤维瘤胃降解的作用效果。结果表明:A.blazei较V.volvac处理和对照组分别提高稻草干物质降解率15.17%(PPV.volvac处理组分别下降8.03%(PPA.blazei的处理效果随微贮时间延长而提高。瘤胃降解的动态分析显示,A.blazei处理可提高稻草的可溶解(a)和可降解利用(b)成分含量约12.4%和16.8%,提高降解速率(c)达0.015 2。V.volvac处理对改善稻草瘤胃降解率没有明显效果(P>0.05)。

Abstract: Rice straw was treated with Agaricus blazei and Valvariella volvac in different periods.The in sacco degradation experiment was carried out to study the effect of pre-culture on improving straw degradation quality.The results showed that comparing with V.volvac treated and untreated groups, the DM degradability of A.blazei treated straw increased by about 15.17%(PPV.volvac treated group, the Heel and Cel contents in residue decreased by 8.03% (PPA.blazei was euhured, the higher degradability was obtained.Dynamic of ruminal degradation revealed that the soluble proportion (a) and degradable proportion (b) of A.blazei treatment increased by 12.4%and 16.8%respectively, and its degradation (c) improved by about 0.0152.On the contrary, V.volvac treatment indicated no significant improvement in straw ruminal degradation quality (P>0.05).
