Why the fridge??

Why the fridge?

We use it for our horses.
Refrigerate after opening. A tube is more than a smaller horse needs.
It will keep in fridge.

I guess that’s just a farmer thing. Unopened tube probably doesn’t matter where you keep it. Partial tube goes in the fridge. Possibly unnecessary, but that’s how I’ve always done it.
