Abstract

Data on 164 Japanese quails were utilized to study the effect of strains, hatches and sex of
chicks on pre-slaughter weight and weights of carcass after bleeding, dressed carcass, eviscerated
carcass, inedible and edible offals and various carcass cuts. The Black strain was superior to Brown
for all the characters except the breast weight. Significant hatch effect was observed for the preslaughter
weight, dressed weight, eviscerated carcass, inedible offals, heart and gizzard. The
sexual dimorphism was not evident for any of the characters studied, except pre-slaughter weight.
Majority of the carcass traits were medium to highly heritable.
