There were evaluated metrics of milk powder feed mixing, consumption of electric power and time of processing digital daily data volume sent to the main PC for cattle cub feeder with an electronic weight control. Mixing 0.5…1.5 kg of milk powder feed dose takes 27…38 s. The final weight differs from the desired one by 3.82…4.55 g. Temperature of feed dose is +32…38 ºC. It is possible to mix any dose within 0.18…1.50 kg with a milk powder concentration about 10 % following a cub feeding plan with non-linear daily gains of weight. A daily consumption of electric power for three diverse types of feeders (milk powder or whole milk only or a combined machine) differs negligibly. It was evaluated to 0.184±0.009 kWh for 60 calves feeding or to 7.0±0.3 W per 1 kg for feed mixing or 28.1±1.3 W per one calf daily feeding. A processing time takes less than 2 s of PC calculation and saving for whole daily data volume received from a feeder using FTP transfer.
