Port Jackson Willow (Acacia Saligna) is very invasive in our part of the world. Hlubi keeps some pigs in Tsitsikama which is 130 km west of where we are. I tried catting some branches to see if they would take to it. They really enjoy it. A free resource perhaps to small farmers who are trying to find affordabe options to supplement the pig feed needs.
