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 .
This research carried out in the Video Center for Research on Animal Production of
the Faculty of Agriculture at Tishreen University with the beginning of the summer of
2010 in order to study the possibility of improving the performance of broiler
chickens
under the conditions of the coastal area and increase economic returns.
Search Results showed that the addition of black bean and thyme powder by 0.5% to a
low-energy diet led to increased average live weight of age (9-28) days totaled 864.9 g
G3)) compared to the control (without the addition), which amounted to an average live
weight has 850.7) g) of the same age
FCR feed conversion ratio stood at 2.63 at the group G1, compared with 1.89 when the
Control CSearch results also showed that the addition of 0.25% of the black bean and
thyme powder led to the live weight increase of 848.6, compared with 670.7 members G1)
g) FCR feed conversion ratio stood at 1.96 at the G4 Group added (0.25% of the black
bean powder and thyme), compared with 2.63 at the G1 group.
