This study examined the effect of rice bran and ground corn substitution levels with Win_prob probiotic fermented corn cob flour (TTJF) and the addition of Zn biocomplex in concentrate feed on the nutrient digestibility of fattening Bali cattle. A total of 12 male Bali cattle aged 1–1.5 years (147–189 kg; 168.08±15.50 kg; KV 9.22%) were tested with 4 treatments × 3 replicates: P0 (control); P1 (bran replaced with 25% TTJF and 15% ground corn); P2 (35% and 25%); P3 (45% and 35%); all treatments supplemented with 100 mg of bio-complexed Zn. Variables: digestible crude protein, digestible energy, and TDN; analysis using ANOVA. The mean showed a downward trend from P0 to P3, but was not significantly different (P>0.05). It was concluded that TTJF could be used up to 45% to replace bran and 35% to replace ground corn from the initial composition of 55% bran + 20% corn in the concentrate, without reducing the digestibility of protein, energy, and TDN in Bali cattle.
