Dry Matter Analysis Results
| Nutrient | As-Fed Basis (%) | Dry Matter Basis (%) |
|---|---|---|
| Protein | 0.0 | 0.00 |
| Fat | 0.0 | 0.00 |
| Fiber | 0.0 | 0.00 |
| Ash | 0.0 | 0.00 |
| Others | 0.0 | 0.00 |
Formula: Dry Matter Basis % = As-Fed Basis % × 100% ÷ (100% - Moisture %)
Note: Higher protein and fat are generally better, lower ash content is preferred
Example Calculation
Dog Food Brand Comparison
Brand A (As-Fed):
• Protein: 30%
• Fat: 6%
• Fiber: 4%
• Moisture: 2%
Brand B (As-Fed):
• Protein: 25%
• Fat: 5%
• Fiber: 4%
• Moisture: 30%
Dry Matter Calculation Results
Brand A (Dry Matter):
• Protein: 30% ÷ (100% - 2%) = 30.61%
• Fat: 6% ÷ 98% = 6.12%
• Fiber: 4% ÷ 98% = 4.08%
Brand B (Dry Matter):
• Protein: 25% ÷ (100% - 30%) = 35.71%
• Fat: 5% ÷ 70% = 7.14%
• Fiber: 4% ÷ 70% = 5.71%
Result: Brand B actually contains more nutrients per dry weight!
Quick Guide
As-Fed Basis
Nutrient percentages including moisture content as shown on pet food labels
Dry Matter Basis
Nutrient percentages after removing all moisture for accurate comparison
Why Convert?
Different moisture levels make direct comparison impossible

Understanding Dry Matter Analysis
What is Dry Matter Basis?
Dry matter basis represents the nutrient content of feed or pet food after all moisture has been removed. This allows for accurate comparison between different products regardless of their moisture content, which can vary significantly between dry kibble (10% moisture) and canned food (80% moisture).
Why is it Important?
- •Enables accurate comparison between different feed types
- •Reveals true nutrient density of products
- •Helps make informed feeding decisions
- •Standard practice in animal nutrition
Calculation Formula
DMB% = AFB% × 100% ÷ (100% - M%)
DMB%: Dry Matter Basis percentage
AFB%: As-Fed Basis percentage
M%: Moisture percentage
Interpretation Guidelines
Higher is Better: Protein, Fat (for active animals)
Moderate is Best: Fiber (varies by animal type)
Lower is Better: Ash content (mineral residue)
Applications
- •Pet Food Selection: Compare different brands and types
- •Livestock Feed: Evaluate feed quality and cost-effectiveness
- •Research: Standardize nutrient content for studies
- •Regulation: Meet nutritional requirements accurately
Tips for Feed Analysis
- •Always check the guaranteed analysis on feed labels
- •Consider your animal's specific nutritional needs
- •Factor in feeding amounts and cost per serving
- •Consult with veterinarians for optimal nutrition plans
