The degradation rate of crude fiber was higher in E.perennis than in Wancao 2.The differences of degradation rate of CP and dry matter between E.perennis and Wancao 2 are not significant.In conclusion,the difference of nutrition among the three kinds of forage crops results from their different biological characteristics.Read More
