This experiment was conducted to investigate the quality of wild flowers and mixed wild flower silages. Silage materials employed ochardgrass and mixed wild flower (orchardgrass, white clover, Achillea sibirica Ledeb., Coreopsistinctoria Nutt., Rudbeckiabicolor Nutt., Centaureacyanus L.). Six kilograms of silage materials cut from each treatment were divided into 3 containers, packed by vacuum, and fermented for 40 days. The orchardgrass silage showed significantly higher contents of crude protein than that of mixed wild flower silage. But the neutral detergent fiber and acid detergent fiber contents of orchardgrass silage were significantly lower than those of mixed wild flower silage. pH and butyric acid of orchardgrass silage were significantly lower than those of mixed wild flower silage, and significantly higher in lactic acid contents. It appears that water soluble carbohydrates needs to be supplemented, being grounded on the results above, into wild flower materials both with high fiber materials and with low substances which need lactic acid fermentation.
