This study investigated the effect of inoculum on the nutritive value of corn silage and the nutrient intakeof sheep fed this silage .Materials and methods In experiment １ (２０００ ) , silage made from １ /４milk line corn was prepared in three different treatments :untreated , lactic acid bacterial inoculum １１３２ and bacterial inoculum ＋ enzyme , respectively . In experiment ２ (２００５ ) , silagemade from ３ /４milk line corn was prepared in three different treatments : untreated , lactic acid bacterial inoculum １１C３３ and１１C３８ , respectively . Sheep were used to determine the nutrient digestibility of corn silages .Results Silages prepared by each method showed high fermentation quality . In experiment １ , the concentrations of EE , GE ,TDN and DE , the digestibility of CP , EE and GE , and the intake of TDN were significantly higher ( p ＜ ０ .０５ ) using silagetreated with １１３２ than in untreated silage . In experiment ２ , the concentration of EE was significantly higher ( p ＜ ０ .０５ ) usingsilage treated with １１C３８ than in untreated silage . The digestibility of EE was significantly higher ( p ＜ ０ .０５ ) for silage treatedwith １１C３３ or １１C３８ than for untreated silage . The intake of TDN with １１C３３ or １１C３８ treatment did not significantly differcompared to that of untreated silage , TDN intake was increased ２０ .６ ％ and ３７ .０ ％ , respectively .
