Let’s dive into everything you need to know about hog weight, piglet weight, and how to weigh pigs without a scale!
What is Pig Weight?
Pig weight refers to the total mass of a pig, which is essential for:
- Tracking daily weight gain
- Estimating feed requirements
- Assessing pig health
- Determining market weight for pigs
A pig’s skin condition can indicate its overall health. A healthy pig enjoys a better quality of life.
To measure pigs’ weight correctly, factors like age, breed, feeding program, and living conditions must be considered.
How Much Do Pigs Weigh?
The weight of hogs varies depending on their age, breed, and purpose. A well-fed pig can reach its target weight in six months.
| Pig Type | Average Weight |
|---|---|
| Market Hogs | 250-290 lbs (5-6 months old) |
| Breeding Sows | 400-500 lbs (mature) |
| Boars | 450-700 lbs (2-3 years old) |
For those wondering “how much does a pig weigh?”, the answer depends on genetics, diet, and health.
Some pigs, like the Duroc pig, have higher growth rates. The Yorkshire pig’s weight also varies based on feeding efficiency.
Online Pig Weight Scale Calculator
If you don’t have a weighing scale for pigs, an online weight scale calculator can estimate a pig’s weight based on girth measurements.
You can also use a net weight calculator to determine the actual meat yield after processing.
How to Measure a Pig’s Weight Without a Scale?
To use a hog weight calculator, input:
- Heart girth (in inches) – Measure behind the front legs
- Length (in inches) – Measure from ear base to tail base
Alternatively, a length plus girth calculator provides instant weight estimates.
Pig Weight Formula
A common formula for pig weight calculation is:
Weight (lbs) = (Heart Girth² × Length) ÷ 400
Example Calculation:
If a pig has:
- Heart Girth = 50 inches
- Length = 45 inches
Then:
Weight = (50² × 45) ÷ 400
= 281.25 lbs
This pig weight formula provides a fairly accurate estimate of a pig’s live weight and hanging weight.
Pig Weight Chart by Age
A pig weight chart helps farmers track pigs’ average weight at different ages.
| Age (Months) | Average Weight (lbs) | Average Weight (kg) |
|---|---|---|
| 1 month | 10 – 20 lbs | 4.5 – 9 kg |
| 2 months | 30 – 40 lbs | 13.5 – 18 kg |
| 3 months | 50 – 70 lbs | 22.5 – 31.5 kg |
| 4 months | 80 – 110 lbs | 36 – 50 kg |
| 5 months | 120 – 150 lbs | 54 – 68 kg |
| 6 months | 160 – 200 lbs | 72 – 90 kg |
For example, a 4-month-old pig weight typically falls between 80-110 lbs.
Pig Weight Gain Calculator
A pig weight gain calculator helps estimate weight changes over time.
| Age Range | Average Daily Gain (lbs/day) |
|---|---|
| Birth – 2 months | 0.75 – 1 lb/day |
| 2 – 4 months | 1.5 – 2 lbs/day |
| 4 – 6 months | 2 – 2.5 lbs/day |
Using a swine growth chart helps predict future weight gain.
