The present study was conducted in order to determine the effects of feeding frequency (FF) on dairy cow performance fed a total mixed ration (TMR) based on chopped alfalfa hay. Eight multiparous early lactation Holstein cows were housed in the individual boxes (4 × 3 m) and fed either once a day (1x) at 0700 h or 4 times a day (4x) at 0100, 0700, 1300 and 1900 h with TMR. The experiment was done as a 2 × 2 crossover design with two 20-d periods. When FF changed from 4x to 1x, dry matter intake (21.1 vs. 20.0 kg/d) and NEL intake (36.4 vs. 34.3 Mcal/d) increased (P
