Feed Conversion Ratio: lb Feed per lb Gain

FCR = feed consumed รท weight gained. Lower is better. Cattle 6-8, swine 2.5-3.5, poultry 1.8-2.2, fish 1.2-1.8. Affects profitability and sustainability.

Calculate Feed Conversion RatioEnter feed consumed and weight gained

Why This Biology Metric Matters

Why: FCR measures how efficiently animals convert feed to body weight. Lower FCR means less feed per pound of gain, reducing cost and environmental impact.

How: FCR = total feed consumed รท total weight gained. Feed efficiency = 1/FCR. Compare to benchmarks by species. Genetics, feed quality, health, and management affect FCR.

  • โ—Poultry and fish have lowest FCR; cattle highest.
  • โ—Improving FCR by 0.1 can significantly reduce feed costs.
  • โ—Feed quality, genetics, and disease affect conversion.

๐Ÿ“‹ Key Takeaways

  • โ€ข FCR = Feed Consumed / Weight Gained. Lower = better efficiency.
  • โ€ข Feed costs = 60โ€“70% of production. Improving FCR cuts costs and boosts profit.
  • โ€ข Benchmarks vary by species: cattle 6โ€“8, swine 2.5โ€“3.5, poultry 1.8โ€“2.2, fish 1.2โ€“1.8.
  • โ€ข FE = 1/FCR. ADG = Weight Gained / (Animals ร— Days).

๐Ÿ“– How FCR Calculation Works

FCR = Feed Consumed / Weight Gained. FE = 1/FCR. ADG = Weight Gained / (Animals ร— Days). Cost/lb = Feed Cost / Weight Gained.

Core Formula

FCR = Total Feed Consumed / Total Weight Gained

โ“ Frequently Asked Questions

What is a good FCR?

Depends on species. Cattle 6โ€“6.5 excellent; swine 2.5โ€“2.8; poultry 1.8โ€“1.9. Lower = better.

How to improve FCR?

Optimize feed formulation, quality, health, housing. Reduce waste. Select efficient genetics.

What affects FCR?

Genetics, feed quality, health, environment (temp, humidity), housing, water, feed waste.

Why is FCR important?

Feed = 60โ€“70% of costs. Better FCR = lower costs, higher profit, less environmental impact.

How to calculate FCR?

FCR = Feed Consumed / Weight Gained. Weight gained = (End - Start) ร— Animals.
