CPN CPN Pet Food Evaluation & Labeling 2 — Questions and Answers
Question 1: In a pet food guaranteed analysis panel, which nutrients are listed as MINIMUM guarantees (rather than maximums)?
- Fat and crude fiber
- Crude protein and crude fat (Correct answer)
- Moisture and ash
- Crude fiber and moisture
Correct answer: Crude protein and crude fat
Crude protein and crude fat are listed as minimums because consumers want to know the least amount present, while moisture and crude fiber are listed as maximums.
Question 2: In what order must ingredients be listed on a US pet food label according to AAFCO model regulations?
- Alphabetically by ingredient name
- By nutritional contribution
- By pre-processing weight in descending order (Correct answer)
- By digestibility coefficient
Correct answer: By pre-processing weight in descending order
Ingredients must be listed in descending order by their weight as added before processing, so the heaviest ingredient by weight appears first on the list.
Question 3: What is the deceptive formulation practice known as 'ingredient splitting' in pet food manufacturing?
- Dividing ingredients into separate manufacturing batches
- Listing one ingredient under multiple forms to make each appear lower in the ranking (Correct answer)
- Using both wet and dry processing for a single ingredient
- Combining multiple protein sources into one ingredient name
Correct answer: Listing one ingredient under multiple forms to make each appear lower in the ranking
Ingredient splitting involves listing a single ingredient in multiple derivative forms (e.g., corn, corn gluten meal, corn flour) so each fraction ranks lower than it would if combined.
Question 4: When the term 'crude' appears before a nutrient (e.g., crude protein, crude fat), what does it specifically indicate?
- The ingredient is unprocessed or raw
- The value is an approximate measurement based on a standard laboratory method (Correct answer)
- The nutrient is of low biological quality
- The nutrient comes from plant sources only
Correct answer: The value is an approximate measurement based on a standard laboratory method
'Crude' refers to the standardized proximate analysis method used in the lab (e.g., Kjeldahl for protein, ether extraction for fat), not the nutrient's quality or processing state.
Question 5: To accurately compare the protein content of a wet food (78% moisture) to a dry food (10% moisture), the clinician should use which basis?
- As-fed basis
- Dry matter basis (Correct answer)
- Caloric basis
- Guaranteed analysis basis
Correct answer: Dry matter basis
Dry matter basis removes moisture from the calculation, allowing direct nutrient comparison between wet and dry foods that would otherwise be distorted by their very different water contents.
Question 6: Why does 'chicken meal' often provide more protein per pound of food than 'chicken' listed as the first ingredient?
- Chicken meal is made from higher-quality muscle tissue
- Chicken includes ~70% water weight, while chicken meal is rendered and dried to ~65% protein (Correct answer)
- Chicken meal contains added protein supplements
- Chicken is restricted to white meat, which has less protein
Correct answer: Chicken includes ~70% water weight, while chicken meal is rendered and dried to ~65% protein
Fresh chicken is approximately 70% moisture and about 18% protein, whereas chicken meal has been rendered and dried, concentrating it to approximately 65% protein on an as-fed basis.
