Well, this is the goats' favorite thing to eat this spring. And the mini donkeys are even stripping off bark from the bigger bushes. But the best use I'm finding now is to use it for wattle fencing. If you cut the bushes to the ground they'll send up lots of water shoots that are straight and by the end of the season can be thicker than your thumb, depending on the size of the roots. And very long and fairly flexible. Great for wattle fencing.
For feeding the goats they have the convenient habit of breaking off very easily when you bend them in half. So I can quickly get a wheel barrow full of leafy branches on rainy days with little effort and no tools. The green wood is also very easy to saw through. In nice weather the goats will follow me around the pasture where I break all the branches that are too tall for them to browse on, so they bend down to a convenient browsing height. This won't harm the bushes at all but will force them to send up more tender shoots from lower on the branches and from the roots - easy for the goats to eat. They like the tender new shoots best of all.
