Enter the cow body weight (lbs) and the dry matter percent (NDF, TDN, etc) into the Dry Matter Intake Calculator. The calculator will evaluate the Dry Matter Intake.

## Dry Matter Intake Formula

The following two example problems outline the steps and information needed to calculate the Dry Matter Intake.

DMI = CBW * .011/NDF

Variables:

- DMI is the Dry Matter Intake (lbs)
- CBW is the cow body weight (lbs)
- NDF is the dry matter percent (NDF, TDN, etc)

To calculate the dry matter intake, multiply the cow body weight by .011, then divide the dry matter percent.

## How to Calculate Dry Matter Intake?

The following steps outline how to calculate the Dry Matter Intake.

- First, determine the cow body weight (lbs).
- Next, determine the dry matter percent (NDF, TDN, etc).
- Next, gather the formula from above = DMI = CBW * .011/NDF.
- Finally, calculate the Dry Matter Intake.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **

Use the following variables as an example problem to test your knowledge.

cow body weight (lbs) = 1300

dry matter percent (NDF, TDN, etc) = 50

DMI = CBW * .011/NDF** **= ?
