CPN Life Stage Nutrition & Feeding Management 1 — Questions and Answers
Question 1: What is the recommended crude protein range (dry matter basis) for growing puppies according to AAFCO guidelines?
- 10–15%
- 18–20%
- 22–32% (Correct answer)
- 35–40%
Correct answer: 22–32%
AAFCO guidelines recommend 22–32% crude protein on a dry matter basis to support the rapid tissue growth of puppies.
Question 2: Which life stage has the highest energy requirement per unit of body weight in cats?
- Adult maintenance
- Senior cats (>11 years)
- Kittens during growth (Correct answer)
- Early-gestating queens
Correct answer: Kittens during growth
Kittens have the highest energy requirement per kg of body weight due to the metabolic demands of rapid growth and thermoregulation.
Question 3: At what age should large breed puppies (>25 kg adult weight) typically transition from puppy to adult food?
- 6 months
- 8 months
- 12–18 months (Correct answer)
- 24 months
Correct answer: 12–18 months
Large breed puppies reach skeletal maturity around 12–18 months and should transition to adult food at that time to avoid excess calcium intake.
Question 4: Which nutrient ratio is most critical for preventing developmental orthopedic disease in growing large breed dogs?
- Omega-6 to omega-3 ratio
- Calcium to phosphorus ratio (Correct answer)
- Sodium to potassium ratio
- Vitamin D to vitamin A ratio
Correct answer: Calcium to phosphorus ratio
An improper calcium-to-phosphorus ratio, especially excess calcium, disrupts bone remodeling and is a primary driver of developmental orthopedic disease in large breed puppies.
Question 5: What feeding frequency is most appropriate for puppies aged 6–12 weeks?
- Once daily
- Twice daily
- 3–4 times daily (Correct answer)
- Free-choice ad libitum only
Correct answer: 3–4 times daily
Puppies aged 6–12 weeks have small stomachs and high energy demands, requiring 3–4 measured meals per day to maintain stable blood glucose.
Question 6: Senior large breed dogs (≥7 years) typically require which nutritional modification to protect kidney health?
- Increased calcium supplementation
- Higher caloric density
- Reduced dietary phosphorus (Correct answer)
- Increased simple carbohydrate content
Correct answer: Reduced dietary phosphorus
Reduced phosphorus intake slows progression of age-related renal decline commonly seen in senior large breed dogs.
Question 7: Which primary energy source sustains neonatal puppies and kittens in the first weeks of life?
- Complex carbohydrates from grains
- Fat from maternal milk (Correct answer)
- Supplemental amino acid solutions
- Glycogen stores from muscle
Correct answer: Fat from maternal milk
Neonatal mammals rely almost entirely on the fat content of maternal milk for energy, as their ability to digest carbohydrates is limited at birth.
