Aim: This research aimed to know the effect of the use of complete feed on Bali cattle fattening performance seen from the carcass characteristics.

Materials and Methods: The cattle employed in this research were 12 male Bali cattle aged between 2 and 2.5 years old based on the teeth estimation. The average initial body weight of the cattle during the research was 181.50±16.51 kg. The complete feed contained Gliricidia sepium, natural grass, ground corn, bran pollard, and rice bran which have been compiled into three types of ration of T1, T2, and T3. The T1 ration contained standard crude protein (CP) and high energy (11% CP; 72% total digestible nutrient [TDN]), and T2 contained medium protein and high energy (13% CP; 72% TDN), while T3 ration contained high protein and high energy (%15 CP; 72% TDN).

Results: The meat percentage of T2 and T3 was relatively the same, but higher than T1 (p<0.05). The bone percentage and meat: A bone ratio of T2 was higher than T1; in contrast, and T3 was relatively the same with T2 and T1 (p<0.05). The weight of slaughter, carcass percentage, and weight of meat, bone, and fat were relatively the same among the treatments.

Conclusion: The application of complete feed with protein source from G. sepium with CP and TDN of 13 and 72%, respectively, can improve carcass percentage and meat: A bone ratio of male Bali cattle fattening. The treatments have not had a positive effect on slaughter weight (kg), hot and cool carcass weight (kg), meat and fat weight (kg), fat percentage, and non-carcass (kg).
