Comparing The Ostrich With The Emu
Both the emu bird and the ostrich are members of the ratite family. This family of birds include the Kiwi from New Zealand, (being the smallest in the family) to the Cassowary from New Guinea, the Rhea from South America, the Emu from Australia, and largest is the Ostrich from Sub-Saharan Africa. The largest distinguishing factor of this family of birds is that they are flightless.
The two ratites used extensively on farms worldwide are the emu bird and the ostrich. These birds are very similar, yet very different. Many of the farm management activities of ostrich farming and emu farming are the same, and we can learn a lot from the other. Yet we must remember that the farming practices are unique due to 2 major factors: Ostriches are not as hardy as emus, and raising ostrich chicks has a much higher mortality rate than emus. The age at which the birds need to be slaughtered also makes a measurable difference in the farm management practices.
The emu is a little smaller than the ostrich. Emu males and females are impossible to tell apart from looks. They sounds they make are unique however: Males make a guttural grunt, and females make a drumming sound. Ostriches are larger than the emu birds. They have more meat. Females and males can be separated by looks. (Males have distinctive black and white feathers, where females are more uniformly grey with white.)
Emu birds are hardy, and very easy to domesticate. They have no aggression towards people, although they can be aggressive towards other livestock. Ostriches are aggressive birds, especially during breeding season. The chicks are harder to raise, with a higher mortality rate. Eggs have a lower hatchability than emu eggs.
The fat deposits are found under the skin over most of the body, but the largest pad of fat is situated on the rump. The emu bird can have up to 14 kg (30lb.) fat. The fat is similar to that of ostriches in composition. The fat deposit found on an ostrich is much smaller than on an emu bird. It is situated as a pad on the undercarriage, and along the spine. The ostrich has much less fat than an emu. Testing of the fat has not been done extensively as with emu fat.
Emu meat is classified as a red meat. Almost no intramuscular fat exists. The meat is seen as a healthy alternative to common red meat such as beef. Ostrich meat is classified as a red meat. Almost no intramuscular fat exists. Ostrich meat is also seen as a healthy alternative to common red meat. Thre is much more meat on an ostrich than an emu.
Emu feathers are made of filaments that do not interlock. Feathers are soft, long and thin.
Feathers accept dyes readily. Emu feathers are unique in that they have a double shaft, after starting as a single shaft. Feathers are mainly used for crafts and flower arrangements. Ostrich feathers are large, and made up of individual filaments. They are striking in color, and absorb dyes readily. Ostrich feathers are in high demand for fashion, interior decorating, arts and crafts, and for the manufacturing of goods like feather dusters.
Emu skin is thinner than ostrich skin, but makes a fine leather that is highly sought after in the fashion industry. Emu leather accepts dye readily. Ostrich skin is thicker than emu skin, and makes a hardy leather that is highly sought after in the fashion industry. Ostrich leather accepts dye readily.
Emu eggs are emerald green, and oblong in shape. The shell is thinner than that of the ostrich egg. Emu eggs are used for crafts, painting and carving. Ostrich eggs are much larger than emu eggs. The egg is white to cream in color, and has a thick shell. Ostrich eggs are also used for crafts, painting and carving.
Farming with emu birds as well as ostriches is a very profitable business. Many unique products and by-products stem from emu farming, although some products are the same or similar to ostrich products
