Nutrition (RER/DER)

Daily energy requirements

Reference notes

DER = RER × multiplier. The species and life-stage selection supplies the reference value. For weight loss, enter target weight. Canine gestation 1.8 covers the first 6 weeks; late gestation and lactation needs rise with litter size.

Enter all required inputs to calculate.

● FORMULA

Select a life stage to set the DER multiplier. Food energy density converts DER to cups per day.

RER = 70 × weight^0.75. DER uses the multiplier beside the input. When food energy is provided: cups/day = DER / kcal per cup. Food per meal divides the daily cups between two meals.

Always verify calculations with established references before clinical use.
