What is the Pig Growth Chart Tracker?
The Pig Growth Chart Tracker plots weight over time against breed growth curves for young pigs. Weight is one of the earliest and easiest signals of a health problem, both gradual weight gain and unexpected weight loss are worth catching early.
Pigs generally live 12-18 years when they are well looked after. As a herbivore, what a pig needs from its diet changes across its life stages. Pigs are highly intelligent and need rooting space, a wallow or shade to manage heat since they cannot sweat, and very strong fencing. They grow far larger than most first-time owners expect. Health problems that show up most often in pigs include sunburn and heat stress, obesity and joint strain, mange, which is part of why tracking this over time pays off.

How does the Pig Growth Chart Tracker work?
The healthy range is drawn from breed or size-variant references for pigs, adjusted for age where growth is still underway. Treat the result as a well-founded estimate. Every pig is an individual, and your vet's judgement outranks any online tool.
What changes the answer
- Breed or size variant: which sets a very different healthy range than a flat species-wide number would
- Age: growing juveniles are compared against a growth curve rather than an adult target
- Body condition: since two animals at the same weight can have very different amounts of muscle versus fat
- Spay/neuter status and activity level, both of which shift metabolic needs
How do you use the Pig Growth Chart Tracker?
- Enter the current weight in whichever unit you use (lb, oz, kg)
- Pick your build for the species (Small or fine-boned, Average, Large or heavy-boned)
- Pick your life stage (Growing, Adult, Senior)
- Enter the age
- Press Calculate, then read the result alongside the sources listed below
Use this alongside your own observation, not instead of it. You notice changes in your pig that no calculator can pick up.

Before you rely on this
Averages hide a lot of variation. The figure here reflects what is typical for pigs, but your pig may sit well outside it for perfectly ordinary reasons. Use the result to spot changes over time in your own animal rather than to compare it against other people's pets.
