The Evaluation On Feeding Of Three Kinds Of Roughage With Low Quality From Micro-Storage Start To Finish

The 3×3 pulls the square experiment is used in this text,so it is convenient to study the feeding value infulunce of the micro-storage on the corn straw, erect milkvetch and korshinsk peashrub.The evaluation index includes palatableness, content of nutrition substance and degradation rate .Besides, the experiment is designed micro-storage experiment on the corn straw, erect milkvetch and korshinsk peashrub and made an analysis to the tendency degradation rate.In order to discuss whether they possess the compose effect, the research result makes clear that:①Micro-storage has little effect to the nutritition substance content of the corn strcw,erect milkvetch and korshinsk peashrub (P>0.05).It makes clear that biostorage can`t improve the nutrition value of the corn straw,erect milkvetch and korshinsk tress peashrub obviously;② Micro-storage can improve the palatableness of the corn straw,erect milkvetch and korshinsk peashrub,obviously the borshinsk peashrub,the utilization rate increased by 37.4%;③However , micro-storage can improve the rumen degradation ,character of dry matter ,neutral washing fiber organic compound,and improve the rumen decomposing rate obviously ;④If you add some Xiasheng enIyme to the process of biostorage ,it will arise a great effect to the degradation of lignin,The lignin degradation rate increased from 8.40% to 19.44%,the ampltnde is 11.04%;⑤If you mix the corn straw and erect milkvetch depending on the ratio of 6 to 4,at the same time ,mix the corn straw and korshinsk peashrub depending on the ratio of 7:3,you will find both of them show the negative group effect.
