The goats did seem to be able to consume mature leaves during the summer, but I would NOT introduce this plant. One of the birth defects is known as crooked calf syndrome, producing crooked legs in the calves or kids. It does need moist soil, so might not spread in an arid environment. If you have a wetter, perhaps wooded environment, on the edge of meadows, for instance, you probably have it in the environment already.
