Enter the total feed given (lbs) and the total animal weight gain (lbs) into the Calculator. The calculator will evaluate the Feed Conversion Rate. 

Feed Conversion Rate Formula

FCR = FG / AWG

Variables:

  • FCR is the Feed Conversion Rate (lbs/lbs)
  • FG is the total feed given (lbs)
  • AWG is the total animal weight gain (lbs)

To calculate Feed Conversion Rate, divide the total feed given by the total animal weight gain.

How to Calculate Feed Conversion Rate?

The following steps outline how to calculate the Feed Conversion Rate.


  1. First, determine the total feed given (lbs). 
  2. Next, determine the total animal weight gain (lbs). 
  3. Next, gather the formula from above = FCR = FG / AWG.
  4. Finally, calculate the Feed Conversion Rate.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

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

total feed given (lbs) = 5,000

total animal weight gain (lbs) = 200

FAQs on Feed Conversion Rate

What is the importance of calculating the Feed Conversion Rate (FCR)?

Calculating the FCR is crucial for farmers and livestock producers as it helps in evaluating the efficiency of the feed used. A lower FCR indicates that less feed is needed to gain a pound of animal body weight, making the feeding process more cost-effective and sustainable.

Can the Feed Conversion Rate vary between different animal species?

Yes, the FCR can vary significantly between different animal species due to differences in metabolic rates, feed digestibility, and growth patterns. For instance, poultry tends to have a lower FCR compared to cattle, meaning they are generally more efficient at converting feed into body weight.

How can one improve the Feed Conversion Rate?

Improving FCR can be achieved through various methods, including optimizing the nutritional content of the feed, ensuring proper feeding practices, managing the health and welfare of the animals, and selecting breeds known for better feed efficiency. Regular monitoring and adjustments based on performance data are also key.

Are there any tools available to help calculate the Feed Conversion Rate more efficiently?

Yes, there are several online calculators and software tools available that can help farmers and livestock producers calculate the FCR more efficiently. These tools often allow for the input of various parameters and can provide quick and accurate calculations, as seen in the links provided on the webpage.
