Abstract

The main objective of this work was to evaluate the means and genetic parameters for egg production
traits of random population of Japanese quail including average egg weight, egg number and egg mass.
The second generation had the highest significant value for egg numbers, egg weights and egg masses
for most weeks from beginning egg production. All heritability estimates for egg numbers were high
except values at first and third week of egg production in the second generation were low (0.09 and
0.003; respectively). All heritability estimates for egg weights were medium values except values for
second week of egg production in the first generation was low (0.02).
