The high price of feed/ration is the biggest problem for farmers, so it requires a way to find quality but cheap feed ingredients, for example using brangkasan/stucker, which are sweet potato leaves and twigs and tubers as feed ingredients substitution for pigs, the protein and energy content is still quite high, but the economic value has not been realized by the farmers. This study aims to determine the effect of some percentage tubers and sweet potato brangkasan/stucker to substitute the concentrate, on the performance of landrace Bali pigs. The study used a Completely Randomized Design method (CRD) with 4 treatments consisting of : T-1 30% concentrate + 60% pollard + 10% sweet potato brangkasan/stucker as control, T-2: 10% concentrate + 60% pollard + 20% sweet potato tuber + 10% sweet potato leaves brangkasan/stucker, T-3:10% concentrate + 50% pollard + 30% sweet potato tuber + 10% sweet potato leaves brangkasan/stucker and T-4:10% concentrate + 40% pollard + 40% tuber +10% sweet potato leaves brangkasan/stucker, which are repeated 5 times. Based on the results of the study, T-2 (giving 10% concentrate + 60% pollard + 20% sweet potato tuber + 10% sweet potato leaves brangkasan/stucker) causing an increase in body weight gain, final body weight and feed consumption, but decrease the feed conversion. Thus, it can be concluded that the substitution of sweet potato tubers and leaves brangkasan/stucker can be used as feed for growth phase landrace Bali pig.
