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 used . 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 .
