Anka and Rugao chicken breed
were reared under the same environment and management. During 12 weeks
age the growth rate of Anka breed was found better than Rugao, and similarly
within breeds Males were grow faster than females. The results shows
that (live weight, carcass weight, dressing out percentage, semi-eviscerated
weight, eviscerated weight, breast muscle weight, leg muscle weight,
heart weight, liver weight and abdominal fat weight) were significantly
(P< 0.01) different in Anka and Rugao breed, however the Abdominal fat
% was statistically non significant (P>0.05) between breeds. Males compared
to females shows significantly (P>0.01) higher live weight, carcass
weight, semi-eviscerated weight, eviscerated weight, breast muscle weight,
liver weight and abdominal fat weight within two breeds. However, Leg
muscle weight, heart weight were non significantly different (P>0.05).
In addition dressing out percentage was significantly (P< 0.05) different
between males and females in Anka breed and non significantly in Rugao
breed. In Anka chicken breed abdominal fat weight was positively correlated
with live weight, carcass weight, breast muscle weight, and percentage
of abdominal fat weight; and it was negatively correlated with leg weight.
In Rugao breed abdominal fat weight was positively correlated with live
weight, carcass weight, breast muscle weight, leg muscle weight and
percentage of abdominal fat. However, the percentage of abdominal fat
weight was negatively correlated with live weight, carcass weight, breast
muscle weight and positively with leg muscle weight and abdominal fat
weight.]]>
