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.

Vaccine Water Dilution Calculator — Dose per Bird for Poultry

Interactive Tool

Vaccine Water Dilution Calculator

Calculate the exact volume of water and skimmed milk powder stabilizer required to dose live vaccines.

🔬 Scientific Disclosure: Vaccine Water Volume Formula

Vaccine Water Volume (L) = (Flock Age in Days * Bird Count * 2) / 1000
Skimmed Milk Powder (SMP) Stabilizer = 2.0 to 2.5 grams per Liter

Drinker lines must be cleared of chlorine using SMP before vaccine distribution. The calculated water volume ensures that the live virus is entirely consumed within 2 hours, preventing viral decay and assuring proper flock immunizing doses.
