15. Weigh the TDF residue.
15.1 Tare a Bag Weigh Holder.
15.2 Remove one SDF filter bag from the desiccant pouch.
15.3 Roll or fold the filter bag, place it in a tared Bag Weigh Holder, and place the Bag Weigh Holder in the center of a
scale.
15.4 Record the weight of the filter bag.
15.5 Repeat steps 15.1 – 15.4 for each SDF filter bag used in the fiber analysis.
16. Determine the Protein content within the TDF residue.
See the “Protein Determination” section of this manual for recommended procedures.
17. Determine the Ash content within the TDF residue.
See the “Ash Determination” section of this manual for recommended procedures.
18. Calculate the % TDF value.
