This experiment was conducted to study the effects of the processing and storage conditions b the fermentation quality of wrapped tropical grass (Sudangrass, Rhodesgrass and Guineagrass) bale silage. 1) Wrapped bale silage with 35-60% moisture content attained good fermentation quality. On the other hand, wrapped bale silage with 60-80% moisture content developed high levels of butyric acid and VBN/TN, and fermentation quality was poor. 2) There was no significant difference between indoor storage and outdoor storage in the fermentation quality of wrapped bale silage with 35-60% moisture content. But with 60-80% moisture content,wrapped bale silage stored indoors had a better fermentation quality than that stored outdoors. 3) The fermentation quality of wrapped bale silage with 35-60% moisture content was not affected by 6 months of outdoor storage under the direct sunlight, but the fermentation quality of that with 60-80% moisture content had deteriorated. It was concluded that the moisture content for processing high quality wrapped bale silage of tropical grass that is stored outdoors for 6 months should be 35-60%
