Genetically, Fries Holstein (FH) dairy cow and its cross have high potency for milk yield, however in the field the yield in average is 10-15 liter per day, much less compared to her genetic potential. lt is suspected that one factor contributed to this problem is lack of nutrient intake or quality variation of ration given. The objective of this research was to examine the substitution of carrot waste to native grass in ration and its effect on production and milk quality of FH cows. The experiment was conducted according to completely randomized block design with four treatments five replications for each treatment. The treatments were Ru (66% native grass + 34% concentrate), R1 (60% native grass + 40% concentrate), R2 (33% native grass + 33% carrot leaves + 34% concentrate), and Ra (33% native grass + 16.5% carrot leaves + 16.5% carrot tuber + 34% concentrate), based on dry matter content. The results suggested that the substitution of carrot waste to native grass increased feed efficiency, milk production 4% FCM, and milk quality.
