Abstract—This study was to evaluate the effects of feed supplements containing tannins, NPN and mineral on milk yield and milk quality of dairy cattle. Nine lactating dairy cows were designed in experiment by a completely randomized design with 3 treatments and 3 replications. Treatment consists of R0: Total Mixed Ration (TMR); RA: TMR + supplements A; RB: TMR + supplement B. The results showed that supplementation of feed supplements A and B were no effect on milk yield and quality but were had significantly different effect on Milk production efficiency for MPE (Milk yield/FCM). Feed supplement A can increase milk yield by 20.88% and feed supplement B increase milk yield by 8.07% compare with only TMR feeding. All supplementation feed supplement had average milk yield higher than control feed. In conclusion the feed supplements increase feed efficiency for dairy cattle.
