This study was carried out to determine the effect of different feed and water withdrawal times prior to slaughtering on organ weights and their relative ratios. Before slaughtering at the ages of 5, 6 and 7 -w, broiler chicks were divided into 6 treatment groups (8 h feed withdrawal (FUN), 8 h FW + 4 h water withdrawal (WW), 12 h FW, 12 h FW + 4 h WW, 16 h FW, 16 h FW +4 h WW) and one control group ad lib not subjected to withdrawals. As parameters, weight of edible (heart, liver, gizzard and abdominal fat) and inedible organ (head, feet, blood, feather and intestine) weights with their relative ratios were determined. Treatments (feed and water deprivations) significantly affected the edible organs heart rate, liver rate and gizzard rate without affecting abdominal fat rate (P less than 0.01). Also, treatments significantly changed the ratios of inedible organs blood, feet rate, feather and intestine (P less than 0.01). Age had significant affect in all edible and inedible organ ratios (P less than 0.01).
