The paper presents results of studies on operational and economic evaluation of three technologies used to prepare and feed total mixed ration (TMR) for cattle. The experiments were conducted on three farms in the Wielkopolska region, in which feed rations of 2662 up to 3595 kg were prepared. Mean operating output capacities for loading operations of feed mixer wagons ranged from approx. 10.5 t·h-1 for front loaders to approx. 12 t·h-1 for the telescope loader. Mean operating output capacities of feed mixer wagons ranged from 2.05 to 5.26 t·h-1. Labour outlays per 1 ton prepared and fed TMR varied, ranging from 0.21 to 0.50 rbh·t-1, while labour outlays at loading of the feed mixer wagon chamber with successive total mixed ration components were comparable, ranging from 0.09 to 0.10 rbh·t-1. The total cost of machine operations was lowest for the T1 technology, amounting to 22.53 zł·t-1, for T2 it was slightly higher at 23.92 zł·t-1, while it was the greatest for T3, amounting to 30.73 zł·t-1.
