1. Eggs from 4 farmed populations of Lesser Rhea (Pterocnemia pennata) were studied to determine their physical and chemical characteristics. 2. None of the physical variables (weight of whole egg, yolk, albumen and shell; proportion of yolk based on egg content; proportion of shell based on entire egg weight; volume; density) showed significant differences between populations. 3. Among chemical variables, moisture, both saturated fatty acids (palmitic 16 : 0 and stearic 18 : 0), one monounsaturated fatty acid (palmitoleic 16:1), and one polyunsaturated fatty acid (arachidonic 20 : 4), did not differ between populations, whereas other variables (protein, lipid and ash contents; fatty acids: oleic 18 : 1, linoleic 18 : 2, linolenic 18 : 3; PUFA; PUFA/SFA; cholesterol) differed significantly.
