I would lean more towards the use of rubber or another material, for several reasons.
1. The planks would almost certainly rot in a very small amount of time, thus having to be replaced.
2. Everything, from manure to pee would seep into the the wood and wouldn't smell to nice after a while.
3. Replacing them would be a sore, considering how much work would go into putting them in.
4. Wood is a magnet for infectants, mould (lots of it), disease, bacteria. What I'm trying to say is that it could get nasty very quickly.
I would definitely recommend rubber matting. It's warm in the winter (relatively), it's going to allow for easy cleaning, and once every few years you may have to replace them, but I can almost guarantee they're not going to be as much of a pain as wood would be.
