A new method of determining in vitro dry matter digestibility (IVDMD) was recently developed in which the digestion is conducted with the forage samples in filter bags. Our objective was to compare the filter bag and conventional IVDMD analysis methods using smooth bromegrass ( Bromus inermis Leyss.), switchgrass ( Panicum virgatum L.), and forage sorghum [ Sorghum bicolor (L.) Moench] samples. In addition, the filter bag analysis systems for determining non‐sequential neutral and acid detergent fiber (NDF and ADF), respectively, were compared with the non‐sequential conventional analysis systems. In the filter bag systems, the forage samples are sealed in filter bags and the analyses are conducted on a batch basis rather than on an individual basis as in the conventional IVDMD and fiber analysis procedures. The filter bag analysis methods produced results similar to the conventional methods and ranked the forage samples in the same relative order.
