How to Weigh a Hog Without a Scale

#0006

There is a formula to estimate hog weight using the heart girth.

Weight = 10.1709 x hearth girth (inches) – 205.7492

My latest boar had a heart girth of 46 inches.

Estimated weight = 10.1709 x 46 – 205.7492

Estimated weight: 262 pounds.

Actual weight: 250 pounds.

The formula seems to work well.

I’ve tested it on many different hogs and the formula gives a good estimate.

Also note that to change ten pounds in weight the girth must increase by one inch.

I also found this tabulated chart which you might find useful.
