1. What is the MER Equation?

The MER (Maintenance Energy Requirement) equation estimates the daily caloric needs for pets based on their weight and activity level. It's commonly used by veterinarians and pet nutritionists to determine appropriate feeding amounts.

2. How Does the Calculator Work?

The calculator uses the MER equation:

Where:

• \( W \) — Weight in kilograms (kg)
• \( F \) — Factor based on activity level and life stage

Explanation: The equation accounts for the non-linear relationship between body weight and metabolic rate, with adjustment factors for different activity levels and physiological states.

3. Importance of MER Calculation

Details: Accurate MER estimation is crucial for maintaining optimal pet weight, preventing obesity or malnutrition, and ensuring proper nutrition for different life stages and activity levels.

4. Using the Calculator

Tips: Enter weight in kilograms, select the appropriate factor based on your pet's status. All values must be valid (weight > 0).

5. Frequently Asked Questions (FAQ)

Q1: What is the 0.75 exponent for?
A: The 0.75 exponent accounts for the fact that metabolic rate doesn't increase linearly with body weight but rather follows a power function.

Q2: How accurate is this formula?
A: It provides a good estimate for most pets, but individual variations may exist based on breed, body composition, and health status.

Q3: Can I use this for all pets?
A: This formula is primarily designed for dogs and cats. Other species may require different calculations.

Q4: What if my pet is overweight?
A: For weight loss programs, use the weight loss factor (1.4) but consult with a veterinarian for a tailored plan.

Q5: Should I adjust for age?
A: Senior pets may require fewer calories. The factor selection accounts for some age-related differences, but individual adjustments may be needed.
