CON = The dairy Holstein cows were fed TMR only; T1 = Fed TMR supplemented with alcohol-fermented feeds (AFF) at a level of 5% of the TMR; T2 = Fed TMR supplemented with AFF at a level of 10% of the TMR; T3 = Fed TMR supplemented with AFF at a level of 15% of the TMR; 4% FCM = Energy corrected yield corresponding to milk containing 4% fat; MUN = Milk urea nitrogen; SCC = Somatic cell counts; Feed efficiency = Milk yield/feed intake; 4% FCM feed efficiency = 4% FCM yield/feed intake.
