Work out feed conversion ratio instantly with clear inputs, formula shown and shareable results.
Divides feed consumed by live weight gain and converts the ratio into feed cost per kilogram of gain.
Feed conversion ratio
FCR = feed consumed / weight gain; feed efficiency is its reciprocal; feed cost per kg gain = FCR x feed price
About 1.5 to 1.7 for broilers, 2.7 to 3.0 for pigs and 6 or more for beef cattle.
Live weight is conventional; carcass-based ratios are higher and must be labelled as such.
