Common Mistakes to Avoid

Comparing EPEF across different target weights

EPEF naturally increases with heavier birds grown to older ages. Only compare EPEF between flocks grown to similar target weights and market ages. Use breed-specific performance objectives as the true benchmark.

Excluding first-week mortality from calculations

All mortality from day of placement must be included. Some growers exclude DOA (dead on arrival) birds, but industry standard EPEF includes total placement-to-harvest mortality.
