This is a one-stop suite of development tools designed to support pet food planning, formulation, and labeling design. From automatic recipe generation and ingredient/nutrition checks to metabolizable energy (ME) calculation using Modified Atwater and NRC-based validation, these tools are ideal for early-stage product development. Everything runs in your browser, and all tools are free to use.

Metabolizable Energy (ME)

Modified Atwater ME Calculation

Modified Atwater ME計算ツール

A free tool that automatically calculates metabolizable energy (ME) based on the Modified Atwater equation—an approach officially adopted by AAFCO. Simply enter the basic nutrient composition of your pet food to generate an ME estimate.

NRC 2006 (CF) ME Calculation

NRC 2006(CF)ME計算ツール

To predict ME more accurately than Modified Atwater, NRC proposes a four-step calculation method. This method adjusts digestibility based on crude fiber content and applies different urinary energy corrections for dogs and cats.

Feeding Amount (RER/MER → g/day)

Daily Feeding Amount Calculation

給与量計算ツール(RER/MER → g/日)

Enter body weight and the food’s metabolizable energy (ME), then select (or manually enter) the MER factor (RER multiplier) by life stage. The tool automatically calculates RER, MER, and the recommended daily feeding amount (g/day), including the formulas used.
