摘要
为探明煮沸时间对滤袋法测定青贮玉米的中性洗涤纤维(NDF)和酸性洗涤纤维(ADF)含量的影响,本研究以Van Soest传统方法所测结果为对照,对煮沸时间30、40、50、60、70、80、90、100、110、120、130min进行优选。结果显示,用滤袋法测定全株玉米青贮和不带穗玉米青贮NDF含量时分别以煮沸110和120min为宜,测定全株玉米青贮和不带穗玉米青贮ADF含量时分别以煮沸60和70min为宜。可见,用滤袋法测定青贮玉米的NDF、ADF含量时,二者的适宜煮沸时间明显不同。
To study the effect of boiling time on the content of NDF and ADF in corn silage by the filter bag technique, the result got from traditional Van Soest method was used as a standard, the different boiling the filter bag tec for det and 70 time （30, 40, 50, 60, 70, 80, 90, 100, 110, 120, 130 min） were screened using ermination of NDF content in whole-plant corn silage and corn silage without ear, and 60 mln were silage and corn si content was very bag technique. the optimum boiling time for determination of ADF content in whole-plant corn lage without ear. Therefore, the optimum boiling time for determination of NDF different from that for determination of ADF content in corn silage by the filter
