Grazing Season:
Average Dry Matter Intake from Pasture for Periods above = ҈
Note: The grazing season average DMI must be calculated as a "weighted" average, as above. To calculate this by hand,
multiply the number of days in each ration by the percent Dry Matter from pasture for each ration. Add all resulting
numbers, then divide by the total number of days for all periods.

Instructions: First, use CCOF's Dry Matter Intake from Pasture form to calculate the percentage of pasture in each ration
fed during the grazing season. Transfer information from your Dry Matter Intake from Pasture forms onto this worksheet
to calculate the average dry matter intake (DMI) from pasture for the entire grazing season. This form can also be used to
calculate dry matter intake over other seasons, including the non-grazing season.

Grazing Season:
Operation Name:
Each type and class of ruminant animal must consume an average of at least 30% of the dry matter demand from pasture during the grazing season.
Requirements for DMI calculation apply only to times within the grazing season, defined as "the period of time when pasture is available for grazing",
and may or may not be continuous, but must be at least 120 days per year. Documentation of rations as actually fed must be available.
If you are using this worksheet in Excel or Adobe, the average will be calculated automatically in the yellow cell above.
