For the purpose of offering basic data to formulate accurate total mixed ration （TMR）, the study was conducted to evaluate nutritional values of whole corn silage comprehensively. One hundred and twenly silage sampies from four ditterent time and five different areas in same longitudinal section per silo were sampled from six silos distributed at Ninghe, Baodi, and Dagang of Tianjin city from November 2008 to the end of July 2009. Conclusion water content and other kinds of nutrition value of these air dry samples were determined, and the data were shown as dry matter basis followed by analysis using the soft of SAS. The experiment results showed thai dry matter content was 221.717±24.503 g·kg^-1 of whole corn silage, and contents of crude protein, crude fat, calcium, phosphowms. neutral detergent fibre, acid detergent fibre were 87.257 ±8.547, 34.194 ±12.308, 3.290±1.226, 2.033 ±0.456, 585.685±69.407, 381.425±91.589 g·kg-1, respectively.
