1. What is Fat Percentage in Dry Matter?

Fat percentage in dry matter (F) is a measure of the fat content in pet food after removing all moisture. It's calculated by dividing total fat (TF) by total dry matter (TD) and multiplying by 100 to get a percentage.

2. How Does the Calculator Work?

The calculator uses the fat percentage formula:

Where:

• \( F \) — Fat percentage in dry matter (%)
• \( TF \) — Total fat content (grams)
• \( TD \) — Total dry matter (grams)

Explanation: The formula calculates what percentage of the dry matter in the food comes from fat.

3. Importance of Fat Percentage Calculation

Details: Knowing the fat percentage in dog food is essential for proper nutrition planning, weight management, and ensuring dogs get appropriate energy levels from their diet.

4. Using the Calculator

Tips: Enter total fat and total dry matter in grams. Both values must be greater than 0 for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is a good fat percentage for dog food?
A: Typically 10-15% for maintenance, up to 20% for active dogs, and higher for puppies or working dogs.

Q2: How do I find the total fat content?
A: Check the guaranteed analysis on the dog food package or contact the manufacturer.

Q3: What's the difference between as-fed and dry matter basis?
A: As-fed includes moisture, while dry matter basis removes all moisture for accurate nutrient comparison.

Q4: Why calculate fat percentage separately?
A: Fat is a concentrated energy source and its proportion affects palatability and caloric density.

Q5: Can I use this for wet/canned food?
A: Yes, but you must first convert to dry matter basis by accounting for the moisture content.
