Batch Financial Summary
ROI: 71.7%Genetics Efficiency Variance
Comparing against Aviagen Ross 308 breed management guidelines for Day 38:
⚠️ An FCR gap of +0.010 represents 556 kg of excess feed consumed, causing a $244.77 profit drag across this flock.
Scale from Clipboard to Poultry ERP
In broiler production, FCR decisions made at harvest arrive 3 weeks too late. DataDaur integrates IoT silo load-cells, automated daily bird scales, and feed formulation directly into real-time analytic flock accounting.
How to use this tool
Enter flock placement, mortality, and harvest age
Input the total day-old chicks placed, mortality count, depletion age in days, and average live body weight per bird in metric (kg) or imperial (lbs) units.
Select commercial broiler genetics benchmark
Choose from Aviagen Ross 308, Cobb-Vantress Cobb 500, Hubbard Classic, or enter custom targets to measure real-time zootechnical variance against standard breed management guidelines.
Input feed intake by total volume or feeding phase
Enter total flock feed consumption in kilograms or model intake across Starter (days 0–10), Grower (days 11–24), and Finisher (days 25–harvest) phases.
Evaluate FCR, adjusted FCR, and European Production Index (EPEF)
The engine calculates raw Feed Conversion Ratio, adjusted FCR normalized to 2.0 kg body weight, and the comprehensive EPEF rating score with visual performance tier classification.
Audit flock operating expenses and liveweight market revenue
Factor in day-old chick (DOC) purchase costs, feed prices per metric ton, veterinary medication, energy/heating, and labor to size total production cost per bird and net batch profit.

Frequently Asked Questions
What is the difference between standard FCR and European Production Efficiency Factor (EPEF)?
Feed Conversion Ratio (FCR) measures biological conversion efficiency: the kilograms of feed required to produce one kilogram of live broiler body weight. European Production Efficiency Factor (EPEF / PEF) is a comprehensive index that combines growth rate, flock livability, and feed efficiency into a single standardized number: (Livability % × Average Weight in kg × 100) / (Age in Days × FCR). While FCR ignores flock mortality and depletion duration, EPEF rewards farms that achieve high weights rapidly with minimal bird losses.
How is adjusted FCR calculated and why is it standardized to 2.0 kg body weight?
Because older, heavier broilers consume more feed per day for basal metabolic maintenance, a flock harvested at 2.80 kg naturally has a higher unadjusted FCR than a flock harvested at 1.90 kg. Adjusted FCR standardizes comparison to a baseline body weight (typically 2.0 kg or 2.5 kg) using genetic performance curves, adjusting by ±0.033 FCR points per 100 grams of liveweight variance. This allows integrated poultry enterprises to fairly compare flock performance across varying slaughter ages.
What is considered a good EPEF score in modern commercial broiler production?
In modern intensive commercial broiler farming, an EPEF above 400 indicates world-class, top-decile management (low mortality under 3.5%, high average daily gain exceeding 63 g/day, and FCR below 1.50). An EPEF of 350 to 400 is considered good and profitable commercial standard. An EPEF of 300 to 350 represents acceptable average performance, while an EPEF below 300 signals critical operational issues such as ventilation failure, subclinical coccidiosis, poor feed quality, or brooding stress.
How does feed conversion efficiency directly impact poultry farm profitability?
Feed represents approximately 65% to 75% of total live broiler production cost. Even a tiny 0.05 variation in FCR across a 25,000-bird broiler house consuming $440/ton feed equals roughly 2,900 kg of wasted feed, representing $1,275+ in lost operating margin per batch. Across six annual cycles, that single shed leaks over $7,600 in net profit purely from feed inefficiency.
