Kleiber's Law Formula:
| From: | To: |
Kleiber's law describes the relationship between an animal's metabolic rate and its body mass. It states that basal metabolic rate scales to the 3/4 power of body mass across species, providing a fundamental principle in comparative physiology.
The calculator uses Kleiber's law formula:
Where:
Explanation: The formula calculates the basal metabolic rate in kilocalories per day based on the dog's body weight, following the allometric scaling principle established by Max Kleiber.
Details: Accurate BMR estimation is crucial for determining appropriate caloric intake, designing feeding regimens, and maintaining optimal health and weight management in dogs.
Tips: Enter the dog's weight in kilograms. The value must be valid (weight > 0). The calculator will provide the basal metabolic rate in kilocalories per day.
Q1: What is basal metabolic rate?
A: Basal metabolic rate is the amount of energy expended while at rest in a neutrally temperate environment, representing the minimum energy needed to maintain basic physiological functions.
Q2: Is this formula specific to dogs?
A: While Kleiber's law applies broadly to mammals, this specific calculation with the 70 constant is commonly used for canine BMR estimation.
Q3: How does BMR relate to daily caloric needs?
A: Daily caloric needs are typically 1.2-1.8 times BMR, depending on activity level, life stage, and health status of the dog.
Q4: Are there limitations to this calculation?
A: This provides an estimate and may need adjustment for individual variations, breed differences, age, and health conditions.
Q5: Should pregnant or lactating dogs use this calculation?
A: No, pregnant and lactating dogs have significantly higher energy requirements and need specialized nutritional calculations.
