Feed Conversion Calculator Guide

The Feed Conversion Ratio (FCR) Calculator measures how efficiently your insects convert feed into harvestable biomass.

How to use it:

Enter the total weight of feed consumed (in kg)

Enter the total harvest weight (in kg)

Click Calculate to see your FCR

Understanding your results:

FCR below 1.6: Excellent — elite commercial performance

FCR 1.6-1.8: Good — well-optimized operation

FCR 1.8-2.1: Average — room for improvement

FCR above 2.1: Needs attention — check feed quality, environment, and health

Key factors that affect FCR:

Feed protein content (optimal 20-25% for crickets)

Temperature (28-32C for fastest growth)

Humidity (60-70% RH)

Stocking density (overcrowding worsens FCR)

Harvest timing (6-8 weeks for maximum weight)

Feed cost represents 40-50% of total production costs, so even a 0.1 improvement in FCR has significant economic impact.
