Abstract
The article used a method of mathematical planning of multi-factor experiments with the aim of determining the parameters of the feed mixer, which ensures that the feed mixture is at the level of zootechnical requirements. From the results of the theoretical studies carried out and one-factor experiments, the following parameters were taken as the factors most affected by the quality of work of the mixer: the frequency of rotation of the Shnek, the amount of transmission per second, the radius of the one that forms the semi-cylindrical part of the lid, the angle at which the
