ABSTRACT
Sixty-seven male and sixty-seven female broiler chickens were fed to appetite with standard
feed mixtures and reared to six weeks of age. After the end of the rearing period, the broilers were
slaughtered and their carcasses dissected into meat, skin plus subcutaneous fat, intramuscular fat,
and bones.
The weight of the skin plus subcutaneous fat from the carcass without the wings (X4), and the
weight of the skinless carcass (X3) are good indicators of fat content (Ž) (r = 0.97) and meat content
(Ŷ) (r = 0.96), respectively, of whole broiler carcasses. These parameters are easy to determine.
The following equations can be recommended for experimental determinations:
Ŷ = 0.6915X3- 18.56 and Ž = 1.1452X4 + 21.05
