How to calculate animal feed conversion efficiency
Feed conversion efficiency measures how effectively an animal converts feed into body weight — a key metric in livestock and aquaculture for evaluating feeding programs and animal performance.
How the calculation works
Feed conversion efficiency = (Weight gained ÷ Feed consumed) × 100.
Example
50 lbs of weight gained from 150 lbs of feed consumed: Efficiency = (50 ÷ 150) × 100 ≈ 33.3%.

Pro Tips for Animal Feed Conversion Efficiency
- This is the inverse framing of feed conversion ratio (FCR = feed consumed ÷ weight gained) — make sure you know which metric a comparison source is using, since higher is better for efficiency but lower is better for FCR.
- Compare efficiency figures only within the same species, age, and feeding program, since conversion efficiency varies enormously across animal types.
Common Animal Feed Conversion Efficiency Mistakes to Avoid
- Confusing feed conversion efficiency (higher is better) with feed conversion ratio (lower is better) — they express the same relationship inverted, and mixing them up reverses your interpretation.
