Farmed ostrich have the capacity to produce a range of excellent products. The original reason for domestication was to save them from extinction as a result of the excessive demand for their feathers. By domesticating the Ostrich, the farmers were able to harvest feathers annually without the need to kill the birds in the wild.
When the feather market collapsed at the outset of the World War 1, the industry contracted significantly. After World War 2, the farmers developed a market for the leather.
However, the real driver for the New Ostrich Industry is the excellent meat the produce.
Ostrich produce a low fat meat, but they do produce a large fat pad on their belly as their energy reserve. This fat is relatively simple to harvest and rendered into an oil that has the potential for many uses including pharmaceutical, cosmetics and consumption.
