Feed Conversion Ratio Calculator

The Feed Conversion Ratio (FCR) measures how efficiently feed is converted into animal weight. A lower FCR indicates better feed efficiency. This calculator helps determine the FCR based on feed consumption and animal weight gain.

What is Feed Conversion Ratio (FCR)?

The Feed Conversion Ratio (FCR) is a measure of feed efficiency in livestock production. It represents the amount of feed (in kilograms) required to produce one kilogram of animal body weight. A lower FCR indicates more efficient feed utilization.

How to Use This Calculator

  1. Enter the total feed consumption (kg) over a specific period
  2. Enter the animal's initial weight (kg)
  3. Enter the animal's final weight (kg)
  4. Click the "Calculate" button

Interpreting Results

A lower FCR is generally better, as it means feed is being converted more efficiently into animal weight. Typical FCR values vary by species and production system:

  • Poultry: 1.4 - 2.4
  • Swine: 2.5 - 3.5
  • Cattle: 6 - 8

Practical Applications

The FCR can help farmers:

  • Compare feed efficiency between different diets
  • Identify nutritional problems
  • Optimize feed costs
  • Make informed decisions about animal management
