Basic ration being given was arranged based on the percentage of dry ingredients namely: 80% of spear grass + 20% of Angsana leaf (A), 80% of spear grass + 20% of Angsana leaf + 10% of silk tree leaf (B), 80% of spear grass + 20% of Angsana leaf + 15% of silk tree leaf (C), and 80% of spear grass + 20% of Angsana leaf + 20% of silk tree leaf (D), The variables being measured were: dry ingredients consumption, nutrients consumption, body weight gain and Feed Conversion Ratio. The result of study showed that with administration of 20% of silk tree leaf in basic ration was significantly improving (P< 0.05) the consumption of dry ingredients and nutrient, and daily weight gain. The result of study concluded that with administration of silk tree leaf in basic ration of spear grass and Angsana leaf increased the growth of Balinese ox.
