Abstract: A total of 12 Holstein dairy cows were used to evaluate the effects of treatments on dairy production and milk quality. Treatments were according to the ratio forage concentrate on diet: T1) 70:30; T2) 65:35; T3) 60:30; T4) 55:45. Twenty kilogram of total diet was offered daily, 10 kg at 07:00 and 15:00 h. The period length of the experiment was 51 day, considering the first 21 day for adaptation. Treatment 1 decreased milk yield and increased fat levels according with weekly measurements. Not effects of treatments on protein, lactose, or non-fat solids levels were observed. Considering with the hold experiment, milk yield level was according with the levels observed during each of 4 weeks; decreasing when alfalfa level increased. Fat milk level was according with the tendency observed weekly, increasing when alfalfa level increased. The levels of protein increased when the amount of concentrate increased. The findings of this experiment suggest that 60% of alfalfa mixed with 40% concentrate offered as total diet in Holstein dairy cows could be a good way to increase yield milk and to improve its quality.
