Use FCR Calculator when you need to compute the feed conversion ratio as feed consumed in kilograms divided by live weight gain in kilograms. Enter Feed consumed and Weight gain using the definitions and units below so the result can be reproduced.

Feed consumed

Feed consumed in kilograms; must not be negative.

Weight gain

Live weight gain in kilograms; must be greater than zero.

The published tool contract uses this rule: Compute the feed conversion ratio as feed consumed in kilograms divided by live weight gain in kilograms.

Feed conversion ratio

Kilograms of feed per kilogram of gain.

A ratio or percentage can conceal the scale of its numerator and denominator and becomes sensitive to measurement error when the denominator is small.

Retain the original Feed consumed and Weight gain values and their units alongside the result. Meat To Bone Ratio is useful when you instead need to compute the carcass meat to bone ratio from lean meat mass and bone mass. PER Calculator provides another view by helping you compute the protein efficiency ratio as weight gain in grams divided by protein consumed in grams; the ratio is signed and cannot fall below minus one.

• Meat To Bone Ratio

  Compute the carcass meat to bone ratio from lean meat mass and bone mass.

• PER Calculator

  Compute the protein efficiency ratio as weight gain in grams divided by protein consumed in grams; the ratio is signed and cannot fall below minus one.

• Brain-Body Ratio

  Compute the gross brain-body mass ratio as brain mass in grams divided by body mass in kilograms.
