Enter the carcass weight and live weight into the calculator to determine the lamb yield. This calculator can also evaluate any of the variables given the others are known.

Lamb Yield Formula

The following formula is used to calculate the yield of a lamb.

LY = (CW / LW) * 100


  • LY is the Lamb Yield (%) CW is the Carcass Weight (kg) LW is the Live Weight (kg)

To calculate the lamb yield, divide the carcass weight by the live weight, then multiply the result by 100 to get the yield percentage.

What is a Lamb Yield?

A Lamb Yield refers to the amount of meat that can be obtained from a lamb carcass. It is usually expressed as a percentage of the lamb’s live weight or carcass weight. Factors such as the lamb’s breed, age, sex, feed, and health can affect the yield. The higher the yield, the more meat a lamb can produce, making it more valuable to farmers and butchers.

How to Calculate Lamb Yield?

The following steps outline how to calculate the Lamb Yield.

  1. First, determine the Carcass Weight (CW) in kilograms.
  2. Next, determine the Live Weight (LW) in kilograms.
  3. Next, use the formula LY = (CW / LW) * 100 to calculate the Lamb Yield.
  4. Finally, calculate the Lamb Yield as a percentage.
  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.

Carcass Weight (CW) = 25 kg

Live Weight (LW) = 30 kg
