Broiler batch performance and EPEF calculator.
Calculate European Production Efficiency Factor from livability, live weight, market age and FCR.
Broiler batch performance and EPEF inputs
Planning tool only. Space allowance, breed performance, ventilation, lighting, welfare, vaccination, medicine, feed formulation and local regulations require qualified poultry-management advice and daily farm monitoring.
Method: EPEF equals livability percentage multiplied by average live weight, divided by age days and FCR, then multiplied by 100.
Inputs used: Livability = 95 %; Average live weight = 2.3 kg; Market age = 35 days; Feed conversion ratio = 1.6
Assumptions: The result uses the values, units and options shown in the input snapshot.
Scope and warnings: Planning tool only. Space allowance, breed performance, ventilation, lighting, welfare, vaccination, medicine, feed formulation and local regulations require qualified poultry-management advice and daily farm monitoring. Rounding and excluded real-world terms can make an external result differ.
How this broiler batch performance and epef calculator works
EPEF equals livability percentage multiplied by average live weight, divided by age days and FCR, then multiplied by 100.
A worked example
95% livability, 2.3 kg at 35 days and 1.6 FCR produces an EPEF of about 390.2.
Can EPEF compare every flock fairly?
Only when age, measurement method, mortality treatment and FCR basis match. Use it as one period metric alongside health, welfare and cost data.
Calculations run on your device. Review your results before exporting or sharing them.
Use one consistent batch period
Livability, average live weight, market age and FCR must come from the same batch and measurement basis. EPEF is only meaningful when these inputs are comparable.
A strong score does not replace welfare, health and economics review. Keep mortality, culls, feed records and weighing method visible alongside it.
