Extraction: Fermented feed sample is mixed and a 25g wet sample is taken and diluted with ml deionized water. Sample mixture sits overnight, then is blended for 2 min and filtered through coarse 25 um particle retention filter paper. Extract is used in the following procedures:.

Mettler-Toledo, Inc. Ammonia 25ml extract is mixed with 75ml deionized water and introduced to a Labconco Rapidstill II model analyzer. Sample is titrated with 0. Result is multiplied by four to obtain total lactic acid.

YSI, Inc. Yellow Springs, Ohio, Lignin Goering, H. Modifications: Fiber residue from the ADF step is recovered on a 1. Greater surface area allows for better filtration. Fiber residue and filter is transfer to a capped tube and approx.

Tubes are gently agitated for 2 hours to insure that all fiber material is continually washed with acid. The contents of the tube after incubation in acid is filtered onto a second filter same type as above which is then rinsed, dried and weighed. The glass fiber filters and lignin residue are than ashed for 2 hours in a furnace to remove lignin organic matter. Finally, the filter and ash residue is weighed back and subtracted from the original weight to determine grams of lignin.

Modifications include: Ash 0. Samples diluted to 50ml and analyzed on ICP. Sample diluted to 50ml and analyzed on axial view ICP. Van Soest, P. Robertson, and B. Dairy Science Modification: Whatman AH glass micro-fiber filters with 1.
