The Allometry of Giant Flightless Birds
… equations generated for anseriforms and ratites suggest mid-shaft femur circumference is the best measure to use in estimating avian body mass. The small sample size of extant ratites makes mass estimate extrapolation to larger extinct species inaccurate. The division of ratites into …

Palaeobiology and flight capacity of volant palaeognaths (Pan-Palaeognathae: Lithornithidae): implications for the common ancestor of extant palaeognaths and early crown birds
… bird diversity comprises the flightless ratites (ostriches, rhea, kiwi, cassowaries, and emu), as well as the partridge-like tinamous that fly powerfully over short distances. As the sister clade of all other crown birds (Neognathae), insight into the biology of early palaeognaths may …

Optimization of dietary protein to energy level for commercial emu (Dromaius novaehollandiae) production to maximize fat yield
This research was conducted to study the optimum dietary protein and energy ratio of finishing diets to sub-adult emu birds for greater fat accretion. The research was done at African Emu Ranch in Muldersdrift, Gauteng. Twenty-six, four to five months old emu birds were reared to an average target …
