Feed Conversion Ratio Calculator

Compare feed consumed against weight gain.

Calculate feed conversion ratio from total feed consumed and total gain. Use it as a planning signal, not as a full performance diagnosis.

Calculate FCR

Enter feed consumed and weight gain for the same animal or group period.

Feed Conversion Ratio-
Total Gain-
Feed per animal-
Note-

FCR needs clean feed and weight records.

The number is only useful when the feed consumed and gain belong to the same period and same group.

How do I measure feed consumed?

Track the feed offered and subtract waste when possible. Group feeding makes this an estimate.

Why can FCR change?

Age, weather, disease, parasite pressure, ration quality and stress can change conversion.

Connect feed to records

Use HerdDeck stock, ration and weight records to review feed efficiency with context.
