Feed ÷ (birds × avg. weight)

Enter birds, avg. weight and feed to see your FCR.

FCR benchmarks for broilers

  • 1.4 – 1.6Excellent
  • 1.6 – 1.8Good / standard commercial range
  • Above 1.8Poor efficiency

Benchmarks apply to market-age birds (35–42 days). Young flocks naturally show a lower FCR, so for birds under 28 days the calculator shows FCR without a rating.

Formula: Running FCR = total feed consumed (kg) ÷ (number of birds × avg. weight in kg). 1 bag = 50 kg.

Track FCR for every batch automatically, day by day against breed standard, with GrowthTak CBF.
