ABSTRACT

Data on body weight at 4 weeks age, age at first egg and cumulative egg production up to 12,
16 and 20 weeks of age of a total 617 Black and Brown strains of Japanese quails were analyzed.
Strains, generations and hatches had significant influence on all the traits studied. Black quails
were significantly heavier and laid more eggs. The quails of fifth generation recorded lowest
least-squares mean for age at first egg with higher egg production. Heritabilities varied from
moderate to high in Black and were high in Brown strains. Genetic and phenotypic correlations
among the traits varied from low to high.
