The authors have developed classification tools for grinding feeds and the most promising directions in the development of tools for the grinding of forages in reducing energy and metal consumption. We have described chopper stem of feed, which provides high performance and good quality of product. In the article, there is an analysis of existing methods of grinding coarse fodder and their classification. The work presents examples of application of stationary and mobile crushers for crushing of grain and roughage, the technical parameters of the equipment for preparation of feed for feeding

The article has a classification of fodder shredders developed on the basis of the analysis of the existing technical means for the preparation of fodders. The constructive technological scheme of the grinder for coarse fodder in a pressed form is proposed. The results of experimental studies in solving the optimization problem-finding the optimal combination of constructive-technological factors of equipment are analyzed, in which a predetermined number of all types of feed will be produced with a higher quality. As optimization criteria, the following were chosen: energy intensity, material grinding time, weighted average particle length

In this article we consider methods of inactivation of anti-nutrient substances of leguminous crops by means of preliminary treatment: melting and extrusion of grain. It has been found that the main anti-nutrient of legumes is a trypsin inhibitor. It is concluded that it is impossible to use leguminous crops as animal feed without preliminary treatment. We have considered issues of use of leguminous crops in feeding farm animals in the form of flour, cake, extraction cake, protein concentrates, milk, green mass, hay, senage, herbal flour and silage, and it has been established that the most promising direction of preparation of leguminous animals for feeding by agricultural animals is preparation of liquid protein suspension
