Restraint and Housing of Ratites
Veterinary Clinics of North America: Food Animal Practice, 1998Large animal practitioners are called upon to assist producers to prevent and control disease and to manage flocks. The concerns that exist in traditional livestock and poultry management are also applicable to ratites. Adequate ventilation, shelter, and space allocation are the foundations of flock health.

Infectious Diseases and Parasites of Ratites
Veterinary Clinics of North America: Food Animal Practice, 1998This article discusses infectious and parasitic disease conditions in the three ratite species. Diseases and parasitic conditions are reviewed in relation to etiology, transmission, pathology, diagnosis, treatment, and prevention. To ensure optimum reproduction and growth of birds on large production units, a veterinarian must understand management in ...

The evolution of ratites and tina1nous
2002Abstract What are the ratites and tinamous? Opinions differ, and will probably continue to differ for many years yet. In this book they are taken to comprise the great flightless birds of the world, ostrich, cassowary, emu, kiwi, rhea, their recently extinct relatives, elephant birds and moas, and their small relatives, the tinamous ...

How Do Ratite Meats Compare with Beef?: Implications for the Ratite Industry
1998Emu and ostrich meats were compared with beef to identify and quantify their sensory attributes. A sensory panel was used to compare U.S. Department of Agriculture Choice top sirloin beef with emu and ostrich meat, both ground and intact forms. Comparisons of sensory quality and acceptability were made after zero, two, four and six months of frozen ...

Science News, 1994
A t dusk in the east Texas town of Montgomery, the pale golden sky gives way to striations of pink and plum light. In the distance, on the Cartwright farm, cows converse in low baritones. From somewhere farther away on this 246-acre spread comes a surprising sound: a gentle, jazzy timbre, resonating like a bass. Music, yes, but not exactly strings.

Thermoregulation in ratites: a review
Australian Journal of Experimental Agriculture, 2008Laboratory and free-ranging studies on the emu, ostrich and kiwi show ratites to be competent homeotherms. While body temperature and basal metabolic rate are lower in ratites than other birds, all of the thermoregulatory adaptations present in other birds are well established in ratites. The thermoneutral zone has been established for the emu and kiwi,

Ratites and tinamous in the future
2002Abstract In the last five hundred years more than half the recent species of large ratites have become extinct, including all the moas and elephant birds and two of the three emus. Two of the three kiwis are greatly reduced in number. Amongst the tinamous, several are now endangered.

A DNA test to sex ratite birds
Molecular Ecology, 2002AbstractDNA‐based sex tests now exist for many avian species. However, none of these tests are widely applicable to ratites. We present DNA sequence data for a locus that is W chromosome‐linked in the kiwi, ostrich, cassowary, rhea, and emu.
