EPEF calculator
EPEF folds weight, age, liveability and FCR into one number. Compute and compare cycles.
verifiedFrom the team that has organised work on poultry farms for years.
EPEF (European Production Efficiency Factor) is the most common way to compare broiler cycles. Formula: (liveability% × weight) ÷ (age × FCR) × 100.
100 minus mortality percent.
Enter to compute dressing percentage.
- EPEF (EWW)
- 357 pkt
- • Wynik 357 pkt — poziom dobry. Typowe rzuty brojlera mieszczą się w ok. 300–400 pkt.
Indicative result based on breed curves (Aviagen Ross/Cobb, Aviagen Turkeys) and public factors. Real values depend on the flock and conditions. The calculator sends no data — it computes in your browser.
FAQ
What is EPEF?add
A single number combining weight, age, liveability and FCR. The higher, the better the cycle.
What EPEF is good?add
Typical cycles land around 300–400 points. Above 400 is very good.
How is dressing percentage different?add
It is carcass weight ÷ live weight (%), computed separately here when you enter carcass weight.
