Abstract: 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 time (30, 40, 50, 60, 70, 80, 90, 100, 110, 120, 130 min) were screened using the filter bag technique. The results showed that the optimum boiling time were 110 and 120 min for determination of NDF content in wholeplant corn silage and corn silage without ear, and 60 and 70 min were the optimum boiling time for determination of ADF content in wholeplant corn silage and corn silage without ear. Therefore, the optimum boiling time for determination of NDF content was very different from that for determination of ADF content in corn silage by the filter bag technique.
