For the purpose of offering basic data to formulate accurate Total Mixed Ration （TMR）, the study was conduct to evaluate nutritional values of whole corn silage comprehensively. One hundred and twenty silage samples from four different 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. Combination 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 that dry matter content was 221.717±24.503g/kg of whole corn silage, and contents of crude protein, crude fat, calcium, phosphorous, neutral detergent fibre, acid detergent fibre were 87.257±8.547g/kg, 34.194±12.308g/kg, 3.290±1.226g/kg, kg, 585.685±69.407g/kg, 381.425±91.589g/kg, respectively. The average value of one hundred and was actual and representative to nutritional value of whole corn silage in Tianjin city. The experiment 2.033±0.456g/ twenty samples results could be used as reference materials of whole corn silage used in dairy farm in Tianjin city.
