The results of the study of the fodder preparation quality by the combined feeding unit that provides simultaneous grinding and mixing the components with the following dosed distribution to the cattle are given. The method of assessing uniformity of feed mixing for the distribution of moisture was tested. Hypothesis of the method for assessing uniformity of fodder mixtures and without making any selection control component is based on the redistribution of moisture feed components to each other in the process of mixing. The production tested method of assessing of the mixture quality was conducted during the preparation of feed for cattle by a mobile fodder preparation combined unit, which provided simultaneous grinding and mixing of the components with the following dosed distribution of them into the troughs or on the feed tables. Dosage of the starting components, when loading them into the hopper, was performed by using of the weighted mobile fodder preparation combined unit. Moisture content of feed ingredients and feed mixtures was determined by the moisture tester VLK-01, a grain moisture tester also can be used (similar Wile-55, Finland). Indicators of the evaluation of the mixing quality according to the method of moisture distribution were compared with the results of no uniformity mixing, defined by the standard method, which involves the addition of a control component (sugar beet seeds) in the amount of 1 % relative to the weight of the feed mixture. After downloading of the latest component into the feed hopper unit, the minimum acceptable requirements of livestock uniform mixing (85 %) is provided by stirring for 6−8 minutes. Indicators of the assessment of mixing by the method of moisture distribution and control component practically coincided during the time of feed processing.
