1. What is the RER Equation?

The RER (Resting Energy Requirement) equation estimates the daily caloric needs for pets at rest. It provides a baseline for determining appropriate feeding amounts for Royal Canin products based on body weight.

2. How Does the Calculator Work?

The calculator uses the RER equation:

Where:

• \( RER \) — Resting Energy Requirement (kcal/day)
• \( BW \) — Body Weight in kilograms (kg)

Explanation: The equation calculates the basic energy needs of a pet at rest, which serves as the foundation for determining appropriate feeding amounts.

3. Importance of RER Calculation

Details: Accurate RER estimation is crucial for proper pet nutrition, weight management, and ensuring pets receive the appropriate amount of Royal Canin food for their specific needs.

4. Using the Calculator

Tips: Enter body weight in kilograms. The value must be valid (weight > 0).

5. Frequently Asked Questions (FAQ)

Q1: What is RER used for?
A: RER provides the baseline caloric requirement for pets at rest, which is then adjusted based on activity level, life stage, and health status to determine actual feeding amounts.

Q2: How does RER differ from MER?
A: MER (Maintenance Energy Requirement) includes adjustments for activity level and is typically 1.2-1.6 times the RER for most adult pets.

Q3: When should I use this calculator?
A: Use this calculator to determine baseline energy needs before adjusting for your pet's specific requirements and consulting feeding guidelines on Royal Canin products.

Q4: Are there limitations to this equation?
A: The equation provides a general estimate and may need adjustment for very young, very old, pregnant, or pets with specific health conditions.

Q5: How should I use this result?
A: Use the RER result as a starting point, then refer to Royal Canin feeding guidelines and consult with your veterinarian for precise feeding recommendations.
