Abstract: The purpose of this study was to determine the performance of Bali cattle fattening in the feedlot system which was fed local grass and concentrate supplementation. A total of 18 fattenening bali cattle with homogeneous body weight (147.29+8.501 kg) were randomly allotted into three feed treatments. The three feed treatments were groups of cattle fed only local grass (Po), local grass+1.5kg of rice bran concentrate (P1); and local grass feed+1.5kg of commercial concentrate (P2), respectively.The results showed that the body final body weight, body weight gains, feed efficiencies, dry matter and organic matter digestibility of cattle in the P1 and P2 treatments were significantly different (P<0.05) higher than in the control (P0) treatment. Supplementation of concentrate in native grass basal diets were not significantly different (P>0.05) on feed consumption. In conclusion that supplementation of concentrate feed (rice bran and commercial concentrate) in the fattening Bali cattle with a feedlot system based on field grass feed can improve the performance of Bali cattle.
