How EPEF is calculated
EPEF = livability % × average weight (kg) × 100 ÷ (FCR × age in days). Below 300 is poor, 300 to 399 commercial, 400 to 449 good and 450 or more excellent. Read how EPEF works and why a high score is not always a high profit.
Let Poultry Curve calculate this for every batch.
Feed, weights and sales flow in from the daily log, so these numbers are always current.
