Effects of fresh and silage Purple-leaved sugarcane (Saccharum sinense Roxb) on ruminal gas production in vitro

摘要

The objective of this study was to investigate the effect of fresh and silage purple-leaved sugarcane on in vitro ruminal gas production.Purple-leaved sugarcane (Saccharum sinense Roxb) was selected to use in this study.Fresh and silage conditions of purple-leaved sugarcane had effect on in vitro gas kinetic parameters and gas productions (P＜0.01).However,fresh and silage purple-leaved sugarcanes affected on the insoluble fractions and methane production at 24 h of incubation.The results suggested that different condition of grass had different effect on in vitro gas and methane production,however,others factors affected on biological properties of anthocyanin,such as molecular weight and structure should be further investigated.
