Hedge as stock fence?

In 1950, our ag teacher in high school was also teaching ww2 vets ag classes which they got paid to attend. Multiflora roses were touted to be wonderful natural fences. He had the high school boys (me) out on the vets farms setting out the roses.. They make a fence that would turn anything from rabbits to mountain goats.. Except for the bare spots where some plants didn't grow. None of the roses we set ever eventialy were used to hold stock.. Birds spread the seeds. They will come up everywhere the ground is left untilled or not sprayed. It is now illeagle to propagate them here. Many boughten roses are grafted to multiflora roots.
You'd be better off with kudzu. At least it can be eaten.
There were several osage orange fence rows around when I was a kid. They take a long time to get big enough for a fence. Stock trims up the low limbs. Then you'd have to put something in spots that aren't filled completly in. You will then have a 40 foot strip of ground that won't grow pasture or crops.

I plan on using a hedge instead of a normal fence for my large stock when I get my land. My plan is to use willow/aspen brush and saplings laid down in the traditional way to grow sideways- willow will root anywhere it touches the ground and encourages other plants to root also-, also cut brush from land clearing in addition to some large root balls/stumps from downed conifers in the area. I also intend to plant young spruces very close together behind this, and in a few years it should be sufficient for stock. I can afford to wait that long because it's going to take several years to build the house, barn, etc. anyway. The spruces won't be big enough to matter for a decade or two, but till then the rest should do ok.
From what I've seen of people who use electric fence or barbed wire, hedge would be so much less of a headache. As long as its managed to be dense and impenetrable, it only gets better.
Also it's cheap or free, most of the materials are already there, just requires work (much more pleasant work than putting up fence posts and stringing wire), and it looks SO much better than wire fences. Totally sustainable, biodegradable, no wires to hurt animals or trees in future years, no fence posts that constantly need attention.
Also most of the scumbags who think nothing of cutting wire to get into a field won't go to the effort of getting through a really good hedge. A fence that keeps what should be in, in, and what should be out, out.
I like the fact that it shelters wildlife, too, although much of that wildlife will be vermin that will prey upon my crops and chickens. But all things considered, I think hedges are the way to go.
They've been used for so long in Europe and obviously they work sufficiently well for the stock over there, so they should work here just as well.
