The current investigation was conducted to study some
productive properties( body weight, body weight gain, feed intake,
feed conversion ratio, carcass composition, and carcass cuts ) on
some broiler strains in Syria ( Ross, Hubbard, and Shefer ).
This study was conducted to use regression equations as indirect methods to
estimate amounts of meat and fat in broiler carcasses of Arbor-Akroz hybrid.
Sixty broiler birds (٣٠ male and ٣٠ female) aged ٤٩ days and reared at a
private farm were use
d . The length of (truck, neck sternum, head, tibia.
lemur, libula, rumb), the width of (head, intervel between iliums, chest,
abdomen), circumference of (thigh, tibia) the high of head and chest and depth
of chest were measured before slaughtering. Birds were slaughtered, cooled for
٢٤ haurs, weighted before and after cooling and the above measure merits
were repeated after slaughtering. Carcasses were dissected and weights of
muscles in the chest, thigh and hypo thigh, amount of fat in the abdominal
cavity and weight of heart and the head were recorded .
