ABSTRACT

This study aimed at determining how the volume of emu egg production and the
egg quality change with the bird age. Observations were conducted over ten successive
emu egg laying seasons. The birds were from own hatching and rearing. At initiation
of observations, the birds were 3 years old and started their 2nd egg laying
season. The egg laying period extended, reaching a maximum (188 days) in 8 years
old female emus, whereas the egg number increased but only to year 6 of layer
life. Older female emus were characterised by low laying performance, which supports
the statement that it is unreasonable to keep emus being older than 7 years for
reproductive purposes. In the first egg laying seasons, the weight of emu eggs
and the shape index significantly changed; then, the value of these indicators
stabilised, being preserved until the end of flock reproductive performance period.

Key words: emu, age, performance, egg quality.
