- Percent Saturation Calculator
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 = ?
