Recent supports provided to livestock operations also supported the development of mechanization levels used in these operations. Technological progress especially in herd management systems, automatic milking, cleaning and hygiene systems led to significant progress also in feeding mechanization. Especially during the last 10 years, significant numbers were achieved in manufacture of feed mixing and distribution machines with a great role in animal feeding in livestock operations. In Turkey, various types of feed mixers with different capacities and constructions are manufactured. These machines generally have single or double augers positioned horizontally or vertically. Such differences in machine constructions are generally resulted from manufacture easiness, cost items and feed characteristics. In present study, considering the average size of livestock operations of Turkey, three feed mixing and distribution machines with different constructions and 6 m3 vagon capacity were compared in terms of operational conditions and assessments were made accordingly.
