Taped Weight vs. Scale Weight

The formula for weighing a pig using a tape measure is: Heart Girth x Heart Girth x Length/400

Length is taken from between the ears to where the tail starts.

This method of weighing a Kunekune is not as accurate as it would be for a traditional hog. Kunekune have a higher percentage of fat, which is lighter than lean muscle. So a round Kunekune might appear to look heavier than they actually are. Consider this when determining the amount of medication you should give your pig.

I have a scale at our farm so I decided to compare the two methods. Here are the results.

Pig Scale Weight Formula Weight Measurements % of Formula Weight

#1 Gilt 172.5 194 43HG x 42L 88%

#2 Barrow 140 156 40HG x 39L 89%

#3 Sow 219.7 273.1 51HG x 42L 80%

#4 Sow 162.4 171 42HG x 39L 94%

#5 Boar 281 281 50HG x 45L 100%

#6 Boar 338 426 59HG x 49L 79%

As you can see from the data above, there is quite a bit of variation from one pig to the next. There was only one pig, Pig #5, that matched the Formula calculation. He was a large, young male with a large boned frame and less fat.

The biggest difference came from our largest male. He was a young boar with extreme length and width. Visually I would have thought he was closer to the Formula Weight. I was very surprised when I read his actual Scale Weight.

If you do not have a scale, using the formula will give you a basic idea of weight, but just keep in mind that the Kunekune is probably slightly lighter than the taped method.

Happy weighing!
