Broiler chicken has advantages in growth rate and conversion ration but these advantages are followed by increase of body fat level. This study was aimed to reduce the increase of body fat level by giving feeding interval treatment on 120 broiler chickens aged 8 days for 28 days. The study was conducted with randomized block design method. The treatment consisted of three feeding intervals (every 6, 8 and 12 hour for a day) and 2 groups of chickens which were maintained separated by sex. Commercial ration that was given contained 23% of protein and 3000 calories of metabolic energies. Observed variables are glucose, triglycerides, ration consumption, conversion ration and abdominal fat content. The result showed that the interval feeding treatment had no significant effect to glucose levels, triglycerides, ration consumption, conversion ratio and abdominal fat but the lowest percentage of carcass quality was achieved by feeding female with 12 hour interval and male 8-hour interval. In conclusion, feeding with 6, 8 and 12 hour interval did not give significant meaning physiologically while the highest percentage of carcass quality is produced in 6 and 8 hour interval for female and 6 and 12 hour interval for male.
