The cost of building silo was lowest for pit silo, whereas it eras highest for concrete silo, but concrete silo seems to be cheaper than muddy silo in a stand-point of their using age. Temperature of silage fermentation was different of about. 4℃. between underground silo (21-23℃) and upperground silo (25-27℃.) in constant temperature of fermentation end period, while between silo covered in with vinyl (21-23℃.) and one no covered (23-27℃.) was different of about 2℃. But in muddy brick silo it was 40℃, above and then showed a sign of putrification due to be attacked by air outdoor through broken parts of wall and to be taken moisture from silage. For spoilage percentage of silage muddy brick silo was 42.2% and so was not found of use at all, but others all were 5% below, especially pit vinyl silo lowest in 1.13%. Treatment of silo for spoilage was significant in evel of 1% and differences between mean value of spoilage percentage of silage, excepting between them of concrete silo and muddy brick vinyl silo, were higher than L. S. D≒1.0780 and so were significant in level of 5%. Among constituents of wild grass silage exude protein was increased. more half than that of wild grass, and therefore, wild grass silage was resulted. higher than corn silage in nutritional value. For acid yield of silage from silos which silage was spoiled lees contained more lactic . acid and was in trend to be good in color and odor. Palatability of silage to Korean cattle, excepted of that from muddy brick silo, was not so different between siloes. For this reason the fact was that silage consumption of Korean cattle was 94% above in all, but the rattles did not take silag from muddy brick silo at all.
