Dry Matter Intake Calculator

Formula

The formula to calculate the Dry Matter Intake (DMI) is:

\[ \text{DMI} = \frac{\text{CBW} \times 0.011}{\text{NDF}} \]

Where:

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

What is Dry Matter Intake?

Dry Matter Intake (DMI) refers to the amount of feed consumed by an animal, excluding its water content. This measure is essential in animal nutrition as it helps determine the actual nutrient intake. The DMI is crucial for formulating balanced diets to ensure the health and productivity of livestock.

Example Calculation

Let's assume the following values:

Cow Body Weight (CBW) = 1500 lbs
Dry Matter Percent (NDF) = 30

Using the formula to calculate the Dry Matter Intake:

\[ \text{DMI} = \frac{1500 \times 0.011}{30} \approx 0.55 \text{ lbs} \]

The Dry Matter Intake is approximately 0.55 lbs.
