Why calculate Dry Matter (DM)?
Maximize nutrient preservation
Better and faster silage fermentation
Optimum levels mean better density, less shrink and aerobic stability at feedout
A factor in purchasing forages
Ration formulation at feedout
When should Dry Matter be calculated (DM)?
Before harvest, sample stalks form different parts of the field, chop them and calculate Dry Matter. Use this with milk-line analysis (kernels one-half to two-thirds milk line) to determine forage harvest timing.
During harvest, sample chopped silage once per hour before it is put into the pile or bunker. Set up to do this at he weigh scale.
Can be done at the same time as Kernel Processing Score and Particle Size Evaluation.
What equipment is needed to test Dry Matter?
Microwave (and a glass of water) or a Koster tester
Gram scale (from an office supply store)
Binder to file results
Log for recording weights, Dry Matter results and storage location
Who can do the Dry Matter calculations?
Anyone who can keep the samples organized and do simple math on a calculator.
Recruit and train two to three people to make sure tests are run over entire harvest
