Poultria is a free, open-access digital academy and decision-support platform for poultry science, disease diagnostics, least-cost feed formulation, and farm management.

How to calculate EPEF in poultry?

European Poultry Efficiency Factor (EPEF) is calculated as: [Livability (%) × Body Weight (kg) × 100] / [Age in Days × FCR]. Scores above 400 indicate top commercial performance.

Is Poultria free for university courses?

Yes, Poultria provides 100% free open access for all university courses, veterinary faculties, and student researchers worldwide.

Hen-Day Egg Production Calculator

Calculate Hen-Day Egg Production Percentage (HDP%) and flock laying yield per hen housed to benchmark against Lohmann Brown and Hy-Line targets.

🔬 Scientific Disclosure: Hen-Day Lay Rate Formula

Hen-Day Egg Production (%) = (Total Eggs Collected Today / Total Live Hens Present Today) * 100

Hen-Day Egg Production measures daily laying efficiency relative to surviving hens. Peak commercial layers reach 93-96% HDP between 24 and 28 weeks of age.
