Effect of additives on the white cover silage

An experiment was conducted to determine the effects of different additives on white clover silage at its vegetative growth period by ensilaging fresh forage in bag with control, formic acid with concentration of 6 mL/kg and 2% of sucrose solution for 360 d. The results of this study showed that addition of formic acid or sucrose improved the silage fermentation quality, significantly decreased the pH value, acetic acid, ammonia nitrogen content of white clover silage (P0.01), significantly increased lactic acid content of white clover silage (P0.01). This study also indicted that addition of formic acid or sucrose increased the dry matter recovery and ADF content of silage (P0.05) and reduced the nitrate content of silage.
