Feed Conversion Ratio (FCR) Formula

Chicken amount = weight in kg × rate per kg. Rate = amount ÷ weight; weight = amount ÷ rate. The raising-cost mode adds flock costs and applies a markup on cost. The optional FCR calculation below uses total feed and live weight gain over the same period.

FCR = (F × D) / WG

Variables:

  • FCR is the feed conversion ratio (a unitless ratio, often written as lb/lb or kg/kg: feed per unit of gain)
  • F is the feed given per day (lb/day or kg/day)
  • D is the number of days over which the weight gain is measured (days)
  • WG is the total weight gain over the period (lb or kg)

To calculate FCR, multiply the feed given per day by the number of days to get total feed for the period (F × D), then divide by the total weight gain (WG).

What is Feed Conversion Ratio (FCR)?

Feed conversion ratio (FCR) measures how much feed is required to produce a unit of weight gain over a period of time. It is commonly used in poultry production to evaluate feed efficiency: a lower FCR means less feed is needed for the same weight gain.

How to Calculate Feed Conversion Ratio (FCR)?

The following steps outline how to calculate FCR.

  1. Determine the feed given per day (F) for the bird or group you are measuring.
  2. Determine the total weight gain over the period (WG).
  3. Determine the number of days (D) over which the weight gain is measured.
  4. Use the formula: FCR = (F × D) / WG.
  5. Calculate FCR as a feed-per-gain ratio (e.g., lb feed per lb gain, or kg feed per kg gain).
  6. In Raising cost mode, enter total feed (F × D) and total live weight gain to check FCR. Feed divided by finished weight is reported separately and is not the same denominator.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

Feed given per day (F) = 5 pounds/day

Weight gain (WG) = 2 pounds

Number of days (D) = 7 days

Total feed = F × D = 5 × 7 = 35 lb, so FCR = 35 / 2 = 17.5 lb feed per lb gain.
