RER Equation:
| From: | To: |
The RER (Resting Energy Requirement) equation estimates the daily caloric needs for puppies at rest. It provides a baseline for determining appropriate feeding amounts for Royal Canin puppy food.
The calculator uses the RER equation:
Where:
Explanation: The equation accounts for the non-linear relationship between body weight and metabolic rate, with smaller animals having higher metabolic rates per unit of body weight.
Details: Accurate RER estimation is crucial for providing appropriate nutrition to growing puppies, ensuring proper development while preventing overfeeding or underfeeding.
Tips: Enter the puppy's body weight in kilograms. The value must be valid (weight > 0). For best results, use the most recent accurate weight measurement.
Q1: What is RER used for in puppy feeding?
A: RER provides the baseline caloric requirement for a resting puppy. Actual feeding amounts may need adjustment based on activity level, growth rate, and specific nutritional needs.
Q2: How often should I recalculate my puppy's RER?
A: Puppies grow rapidly, so recalculate every 2-4 weeks or whenever there's a significant change in weight.
Q3: Is this calculation suitable for all dog breeds?
A: While the equation works for most breeds, giant breeds and very small breeds may have slightly different metabolic requirements. Consult your veterinarian for breed-specific advice.
Q4: How do I convert RER to actual feeding amounts?
A: Check the caloric content of your Royal Canin puppy food and divide the RER by the kcal/cup or kcal/gram value to determine the appropriate feeding amount.
Q5: When should I switch from puppy to adult food?
A: This varies by breed size. Small breeds may switch at 9-12 months, medium breeds at 12 months, large breeds at 15-18 months, and giant breeds at 18-24 months.
