摘　　要：2008年11月～2009年7月在天津市选取宁河县、宝坻区、大港区三区县的6个青贮窖,按照每窖4个不同使用时间、同一青贮窖一个纵切面的5个代表点,采集了120个样品,样品风干制样后测定其绝干水分值和各种营养成分含量。结果表明:天津地区全株玉米青贮的干物质含量为221.717±24.503g/kg;以干物质基础计,粗蛋白质含量为87.257±8.547g/kg,粗脂肪含量为34.194±12.308g/kg,钙含量为3.290±1.226g/kg,磷含量为2.033±0.456g/kg,中性洗涤纤维为585.685±69.407g/kg,酸性洗涤纤维为381.425±91.589g/kg。120个样品平均值真实反映了天津市全株玉米青贮的营养价值,可以作为天津市奶牛场应用全株玉米青贮配制全混合日粮的参考依据。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.
