We used Boers for acacia contoll in Zimbabwe, selling the kids off the dam at 3 1/2-4 months, making a very profitable sideline to the cattle, with only minerals, vaccinations and electric fencing as overheads.
I started the Imbuzi herd when I first came to England, clearing up horse paddocks of thistles, docks and other common weeds, and vacant plots of willow, elder and similar invasive scrub, being paid for clearing, and selling wethers to a niche market. I have been asked to start up the goats again since my return, as there is a big demand for goat meat here.
