Effects of additives on silage quality and in vitro digestibility of Lespedeza hedysaroides silage

Abstract

Abstract: Lespedeza hedysaroides silage was made from L. hedysaroides alone or by adding LaLsIL dry (0.000 5%, 0.001 0%, 0.002 0%, 0.007 0%) and Micromanger H/M (0.001 135%, 0.003 405%, 0.004 450%). L. hedysaroides was ensiled in plastic bags under vacuum. After 90 days, samples were analysised for silage quality and in vitro digestibility of L. hedysaroides. The treatments with LaLsIL dry and Micromanger H/M had higher lactic acid contents than the CK (P<0.05) while the content of butyric acid and ammonium nitrogen were lower (P<0.05). The Flieg evaluation method of silage showed that the fermentation quality was worst in directly ensiled L. hedysaroides, and that both treated silages had better fermentation quality than the CK. The treatments of LaLsIL dry and Micromanger H/M improved the fermentation quality and in vitro DM, CP and NDF digestibility of L. hedysaroides silage.
