Abstract | Utilization of potential swamp forages, by-product of the palm oil industry, and cassava is a strategy in the improvement of cattle feed. The purpose of this study was to evaluate the effect of cassava leaves, palm oil sludge, and yeast supplementation on a ration based on Kumpai grass (Hymenachne amplexicaulis (Rudge) Nees) on the performance of Bali heifers. Twelve Bali heifers were allocated into two groups. First group was fed with control diet consisting of 70% Kumpai grass + 30% concentrate (R0) while second group (R1) was fed a diet consisting of 55% Kumpai grass + 15% concentrate + 15% palm oil sludge (POS) + 15% cassava leaves + 5 g yeast (Saccharomyces cerevisiae)/head/d. The variables measured in this study were intake, digestibility of dry matter, organic matter, crude protein, neutral detergent fiber, acid detergent fiber, average daily gain, feed conversion ratio, and farmer income. Data were analyzed by independent t-test. The results showed that the supplemented diet had a significant performance by improving the intake of dry matter, organic matter, and crude protein. Moreover, it also followed by increasing the digestibility of dry matter, organic matter, crude protein, neutral detergent fiber, and acid detergent fiber, average daily gain, feed conversion ratio, and farmer income. Supplementation of palm oil sludge, cassava leaves, and yeast in the Kumpai grass-based ration significantly increased the performance of Bali heifers. Heifers fed the supplements gave a higher income than those without supplements.
