摘　　要：为配制奶牛全混合日粮准确提供基础数据,以全株玉米青贮为研究对象,系统地对其进行了营养价值评定。选取天津市宁河县、宝坻区、大港区3个区县的6个青贮窖,按照每窖4个不同使用时间、相同青贮窖1个纵切面的5个代表点,采集了120个样品。结果表明,天津地区全株玉米青贮饲料的干物质含量为221.717±24.503g·kg-1;以干物质基础计,粗蛋白质含量为87.257±8.547g·kg-1,粗脂肪含量为34.194±12.308g·kg-1,钙含量为3.290±1.226g·kg-1,磷含量为2.033±0.456g·kg-1,中性洗涤纤维为585.685±69.407g·kg-1,酸性洗涤纤维为381.425±91.589g·kg-1。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.
