European Production Efficiency Factor (EPEF)
Evaluate overall broiler batch performance incorporating livability, body weight, age, and FCR.
Enter Parameters
Reference Details
Formula Used
- EPEF: European Production Efficiency Factor
- Livability %: Survival rate percentage
- Average Weight: Mean bird body weight in kg
- Age: Total growth period in days
(95% * 2.1kg * 100) / (38 days * 1.55 FCR) = 338 EPEF.
1. Purpose
EPEF standardizes performance metrics to compare different broiler houses and seasons fairly.
2. When to Use
Calculate at harvest day to benchmark performance across crops.
3. Required Inputs
To get started, you will need the following inputs:
- Livability (%): Survival rate of the flock.
- Average Weight (kg): Mean body weight.
- Age (Days): Total grow-out period.
- FCR: Final feed conversion ratio.
4. Formula Used
The platform utilizes the following equation: $$\text{EPEF = (Livability % * Average Weight kg * 100) / (Age * FCR)}$$
5. Worked Example
(95% * 2.1kg * 100) / (38 days * 1.55 FCR) = 19950 / 58.9 = 338.7 EPEF.
6. Result Interpretation
Here are the performance thresholds: Excellent: >= 400. Good: 350 - 399. Needs Improvement: < 350.
7. Recommendations
Ensure proper husbandry standards:
- Review feed and water lines.
- Monitor temperature and ventilation parameters.
- Record daily metrics.
8. Common Mistakes
Watch out for these common errors:
- Mixing up chick placement numbers.
- Using inaccurate final FCR estimates.
9. Frequently Asked Questions (FAQ)
Q: Why is EPEF important? A: It combines survival, growth speed, and feed conversion efficiency into a single index score.
