This experiment aimed to determine the effect of additive sources on banana leaf and pseudo-stem (BLS) silage and evaluate the effect of using BLS silage in the diet of growing wild crossbred boar. First experiment was arranged with a completely randomized design with 04 treatments and 04 replicates. The ratio of materials was calculated as a dry matter ratio and the treatments were control (BS): 99.5% wilting BLS + 0.5% salt; treatment 1 (BSC): 94.5% wilting BLS + 5% corn meal + 0.5% salt; treatment 2 (BSB): 94.5% wilting BLS + 5% rice bran + 0.5% salt; treatment 3 (BSM): 94.5% wilting BLS + 5% sugar cane molasses + 0.5% salt. The second experiment was arranged into a completely randomized design, consisting of three treatments and four replicates. The treatments were control group (BSM0): 70% rice bran + 30% water spinach (based on DM); treatment 1 (BSM10): 10% BSM silage + 60% rice bran + 30% water spinach; treatment 3 (BSM20): 20% BSM silage + 50% rice bran + 30% water spinach. The results from the first experiment showed that BLS mixed with 5% sugar cane molasses could improve the silage quality by decreasing pH after 7 days of ensiling and NH 3-N content within the acceptable range for feed silage quality. In addition, wild crossbred boar can consume BSM up to 10% without negative impacts on feed intake and weight gain. But, 20% BSM in the diet decreased weight gain and remained unchanged in feed intake throughout the study. It was found that 5% sugar cane molasses can effectively ensile with BSL, and that BSM may substitute 10% rice bran in the diet of growing wild crossbred boars.
