The formula to calculate the Pig Weight (PW) is:
\[ \text{PW} = \frac{\text{HG}^2 \cdot \text{L}}{400} \]
Where:
Pig weight is the mass of a pig, which can be estimated without a scale by using the heart girth and length measurements. The heart girth is the circumference of the pig measured directly behind the front legs, and the length is the distance from the base of the ears to the base of the tail.
Let's consider an example:
Using the formula to calculate the Pig Weight:
\[ \text{PW} = \frac{50^2 \cdot 60}{400} = 375 \, \text{lbs} \]
This demonstrates that with a heart girth of 50 inches and a length of 60 inches, the pig weight would be approximately 375 lbs.
