Effect of using additives at ensiling on the fermentation quality of common reed (Phragmites communis Trin.) silage

摘要

The common reed (Phragmites communis Trin.) is a wild grass species widely distributed throughout Japan and the world, growing in thousands of abandoned paddy fields and riverside sites. Most of the common reed in Japan is burned or left to become a weed that grows thickly in canals and reclaimed lands, becoming breeding places for diseases and pests (Holm et al. 1977). The biodiversity of plants can be disrupted by an expanding community of common reed whose sward height is 1.5^1.0 m (Ailstock etal.2001). The common reed should be controlled and made use of if possible, and a role for common reed as feed may solve a number of issues regarding this species. The common reed grown in marsh can be harvested as round baled silage using a chopping wholecrop harvester (WB1030DX, Takakita Co., Mie, Japan) and a self-propelled bale wrapper (SW1110W, Takakita Co., Mie, Japan). However, few studies have been conducted on methods of preparing high-quality silage out of common reed. Here we conducted several trials using a small-scale system to determine the effects of adding glucose, lactic acid bacteria (LAB) and acremonium cellulase at ensiling on the fermentation quality of common reed silage.
