The Purina Feed Calculator helps pet owners and veterinarians determine the appropriate daily feeding amount based on a pet's Daily Energy Requirements (DER) and the calorie content of the specific food product.
The calculator uses the simple formula:
Where:
Explanation: This calculation ensures your pet receives the precise amount of food needed to meet their daily energy requirements based on the specific calorie density of their food.
Details: Accurate feeding calculations are essential for maintaining optimal pet health, preventing obesity, and ensuring proper nutrition for different life stages and activity levels.
Tips: Enter the DER value in kcal/day (consult your veterinarian for accurate DER calculation) and the calorie content per unit of your pet food (found on packaging). All values must be valid positive numbers.
Q1: How do I determine my pet's DER?
A: DER depends on factors like weight, age, activity level, and health status. Consult your veterinarian for an accurate DER calculation specific to your pet.
Q2: Where can I find the calorie content of my pet food?
A: The calorie content is typically listed on the packaging under "Guaranteed Analysis" or "Nutritional Information," usually expressed as kcal/cup or kcal/kg.
Q3: Should I adjust feeding amounts for special conditions?
A: Yes, pets with medical conditions, pregnancy, lactation, or high activity levels may require adjusted feeding amounts. Always consult your veterinarian.
Q4: How often should I recalculate feeding amounts?
A: Recalculate whenever your pet's weight changes significantly, when switching foods, or if there are changes in activity level or health status.
Q5: Is this calculator suitable for all pets?
A: While the formula works for most pets, specific nutritional needs may vary. Always consult with your veterinarian for personalized feeding recommendations.
