Abstract
The article investigates the optimization of feeding and has developed a formulation, machines, and technology for the preparation of feed additives for cattle with biologically active substances in order to increase productivity. The article investigates the processing in new crushers of grain product waste, in which feed carbohydrates and, first of all, starch undergoes significant changes, and also creates the technological possibility of introducing missing micro- and macroelements in the cattle ration into the feed composition, and increasing the productivity of animals by increasing the transformation of feed nutrients into products. The article presents the results of the efficiency analysis of use and a theoretical study of the geometric and kinematic parameters of a roll crusher with a convex-concave roll profile, as well as a new method for determining the energy intensity of the crushing process of grain products. The results of theoretical research are confirmed experimentally. This research is funded by the Science Committee of the Ministry of Education and Science of the Republic of Kazakhstan (Grant No. AR09562749 "Improvement of the formulation and technology of compound feeds and feed additives for farm animals").
