The present study was carried out to investigate the effect of fat sources on feed intake, nutrients digestibility and organ weight of broiler chicken. Forty-five Arbor Acre broiler commercial chicks, seven day old, were used in a Completely Randomized Design. Birds were individually housed in cage and distilled water was fully supplied. The experiment lasted 21 days. The experimental diets were contained three sources of fat [Tallow (T), Soybean oil (SBO) and Krabok fat (KF)]. At the end of the experiment, it was found that average daily feed intake (ADFI) was 45.43, 41.75 and 46.62 g/d in birds fed T, SBO and KF, respectively (P>0.05). Average daily gain (ADG)and feed conversion ratio (FCR) were not statistically different (P>0.05) between groups (22.42, 22.96 and 22.96; 1.97, 2.08 and 2.07, respectively). There was significantly different (P<0.05) in abdominal fat, liver and intestine weight. Birds fed SBO were lowest in abdominal fat compared with birds fed T and KF while birds fed SBO was th heaviest in liver and intestine weight compared with birds fed T and KF. Also, birds fed SBO were longer in small and large intestine than in birds fed T and KF (P > 0.05). It can be concluded that SBO was enhanced organ weight. While KF can be used as fat source for broiler chicken without any affect on growth performance. However, it is warrant further research to find out the effect of krabok fat on carcass quality
