AB  - This study was conducted to determine the
influence of sex on relationship among carcass traits
(carcass weight, breast, drumstick, thigh, wings) and
morphometric traits (body weight, breast girth, keel
length, shank length, thigh length, wing length and body
length) in broiler chicken. And also to evaluate correlated
relationship between the morphometric traits and carcass
traits. The 60 broiler birds were divided into 2 treatment
groups (male and female) each group was replicated thrice
with 10 birds per replicate. The birds were rear in deep
litter system till the attain 56 days of age, body weight
and morphometric traits measurements were taken on
the 56 day. The 18 birds (9 from each group) were
randomly selected, slaughtered and the carcass traits
measured and recorded. The data obtained from these
studies were subjected to Pearson correlation analysis.
The correlated relationship among most carcass traits
and morphometric traits were significantly positive
(p<0.001) with correlation coefficients ranging from
0.01-0.681 in Males (M) Females (F) and in combination
of Males and Female (M+F). The correlation between
morphometric traits and carcass traits showed that breast
girth and live body weight were positively and
significantly (p<0.001) correlated with all carcass traits in
all the sex groups. The observed significant relationship
among the morphometric traits and carcass traits as well
as between morphometric traits and carcass traits is an
indication of the existence of high level of dependency
amongst these traits, thus improvement in any one of
these traits would elicit a correlated response in the other
traits. More so, the positive and significant correlated
relationship between carcass traits and breast girth
indicate that breast girth can be used as indirect selection
criteria for carcass traits in broiler chickens.
