Is farm horse fence board pressure treated?

I'm building some furniture pieces using old (20 years?) farm horse fence boards. When I cut into it, it appears to be oak from the grain. It also has a very slight red tint to it in areas. Anyhow, I can't tell if it's pressure treated. The outsides of it are very worn and weather beaten but the insides are solid as a rock.

Anyone know if this type of fence board is typically pressure treated? Does old pressure treated wood still look yellowish?

I doubt it's PT as horses sometimes chew fence old PT wouldn't have been a good idea.

I can't imagine oak unless it came from the owners own trees that he had milled.

Southern yellow pine maybe? What's a prominent wood used in your area? Other than typical softwoods at the home center?

Around here I would have guessed cedar.

Red cedar would be my guess. It's common, cheap and naturally resists rotting & insects so it's often used for fence posts so it's not a stretch that it would be used for fence rails/boards as well.

There are quite a few oak farm fences [barn siding too] around here. The boards come straight from the saw mill and aren't treated, most don't even get stained.

Thanks for the replies! Its definitely not cedar. It feels too dense to be pine, the grain just really looks like oak, and, the boards are HEAVY. They are extremely dense. At any rate, I wasn't so much worried about what type of wood it is/was as much as whether or not it was PT. The point about horses chewing on it makes perfect sense.

thanks again!
