As you can see, it contains a huge amount of water, a hint of salt, quite a bit of phosphorus and acidic content, and a little calcium.
This means that unfortunately, it is not a great food for piggies to eat due to amount of water it has in it.
Eating too much of it, will give them bloat and they will eat all of what you give them.
It is best avoided as a food for them.
