Abstract A 12 weeks feeding trial was conducted to evaluate the effect of increasing proportion of mixed vegetable wastes (MVW) in combination with corn stover (CS) as basal diet on dry matter feed intake (DMI), dry matter digestibility (DMD), average daily gain (ADG) and income feed cost (IOFC) of Bali bulls supplemented with rice bran. Twenty four Bali bulls (159.29 kg) were allocated to 4 dietary treatments, in a completely randomized block design. Each dietary treatment was repeated 6 times. The dietary treatment include CS:MVW (100:0), (80:20), (60:40), (40:60), that was offered ad libitum . Rice bran was added to all treatment at the level of 0.5% of bull weight per day. Increasing proportion of MVW in combination with CS ad libitum resulted in a significant increase (P<0.05) in DMI, DMD, ADG and IOFC of Bali bull supplemented with RB. Bali bulls received CS:MVW (100:0) ad libitum had the lowest total DMI,DMD, ADG and IOFC value, while at the similar parameters, Bali bulls treated with CS:MVW (40:60) ad libitum , showed the highest: It was concluded that MVW can be included as a basal diet up to 60% with high profitability for Bali cattle.
