1. What is Dry Matter Protein?

Dry Matter Protein (DMP) is the protein content of a food item expressed as a percentage of the dry matter, excluding moisture. It provides a more accurate comparison of protein content between foods with different moisture levels.

2. How Does the Calculator Work?

The calculator uses the dry matter protein formula:

\[ DM\ Protein = \frac{Protein}{100 - Moisture} \times 100 \]

Where:

\( Protein \) — Protein content as percentage of wet weight
\( Moisture \) — Moisture content as percentage of wet weight

Explanation: The formula removes the moisture component to show the protein concentration in the dry portion of the food.

3. Importance of Dry Matter Protein

Details: DMP is crucial for comparing protein content across different food products, especially when moisture content varies significantly. It's widely used in pet food, livestock feed, and human nutrition analysis.

4. Using the Calculator

Tips: Enter protein and moisture percentages (both as wet weight basis). Values must be valid (0-100% for moisture, with moisture < 100%).

5. Frequently Asked Questions (FAQ)

Q1: Why calculate dry matter protein instead of using as-fed values?
A: As-fed values include moisture, which can make high-moisture foods appear to have less protein when in fact their dry matter protein may be comparable to drier foods.

Q2: What's a typical dry matter protein range for pet foods?
A: Dry pet foods typically range 25-40% DMP, while wet foods might be 40-60% DMP when converted from their as-fed values.

Q3: How does moisture affect protein percentage?
A: Higher moisture dilutes the protein percentage in as-fed values. Two foods could have identical protein content but very different as-fed percentages if one has more water.

Q4: Can this be used for any food product?
A: Yes, this calculation works for any food where you know the protein and moisture content on an as-fed basis.

Q5: What's the difference between crude protein and dry matter protein?
A: Crude protein measures total nitrogen content, while dry matter protein expresses that value relative to the dry portion of the food.
