How to Use the Feed Conversion Ratio Calculator
Calculate feed utilization efficiency across agricultural species:
Enter Feed Intake
Input total weight of feed fed to animals.
Enter Weight Gain
Input total live weight gained during feeding trial.
Calculate FCR
Engine computes FCR = Total Feed / Weight Gain.
Compare Benchmarks
Compare FCR against species standards (Poultry ~1.6, Swine ~2.8, Cattle ~6.0, Tilapia ~1.2).

Animal Science Guide: Feed Conversion Ratios & Agricultural Economics
Feed Conversion Ratio (FCR) is the single most important profitability metric in livestock production and aquaculture. Because feed accounts for 60% to 70% of total production costs, improving FCR directly enhances farm sustainability and margin.
Frequently Asked Questions
?Is a higher or lower FCR better?
A LOWER FCR is better because it means fewer pounds of feed are required to produce one pound of body weight gain.
