The objectives of this research were to examine the substitution of carrot waste to native grass in diet and its effect on rumen microbial population and diet economic efficiency of FH cows. The experimental design was Randomized Block Design with four treatments each replicated five times. The treatments were R0 (66% native grass + 34% concentrate), R1 (60% native grass + 40% concentrate), R2 (33% native grass + 33% carrot leaf + 34% concentrate), dan R3 (33% native grass + 16.5% carrot leaf + 16.5% carrot tuber + 34% concentrate) all based on dry matter content of feed offered. The results suggested that the substitution of carrot waste to native grass were significantly (P<0.05) affected to rumen protozoa population and diet economic efficiency (income over jieed cost = IOFC) but not on rumen bacteria population. The highest IOF C value was R2 (substitution of carrot leaf to native grass).
