Mathematical planning of a multi-factor experiment and optimization of the feed extrusion process

To increase the level of protein and fat in milk, it is necessary to increase the total amount of feed fed, the diet must be balanced in energy, protein, fiber, minerals and vitamins; the feed must be of high quality. Oilseed waste produced during post-harvest processing and industrial processing contains a sufficient amount of protein and raw fat that can be used in animal feeding diets to increase milk productivity, and when using advanced processing methods, such as extrusion, it becomes a source of environmentally friendly vegetable protein that can increase the nutritional value of the feed several times. In order to study the efficiency of the technological process, the dependencies of quality parameters were determined. Using mathematical methods of planning a multi-factor experiment, a mathematical model of the extrusion process of feed raw materials was developed. The obtained model is used to identify recommended modes of extrusion of feed raw materials from post-harvest waste.
