Feed Conversion Ratio (FCR)

FCR measures how efficiently animals convert feed into body weight. A lower FCR is better — it means less feed is needed per unit of weight gain.

FCR = Feed Consumed / Weight Gained
  • Poultry (broilers): FCR ~ 1.6–2.0
  • Pigs: FCR ~ 2.5–3.5
  • Cattle (feedlot): FCR ~ 5.0–8.0
  • Fish (catfish): FCR ~ 1.5–2.0
