Abstract
The experimental study presented in the article forms the basis for designing a dispenser servicing a robotic feed table on livestock farms. In the introduction, the author analyzes trends in the development of machines for on-farm production of compound feeds using dosing and weighing equipment, and describes the role and key performance indicators of the use of compound feeds of on-farm production for livestock breeding complexes. The articles presents a method for optimizing the design parameters of screw-type feed additive dispensers, a schematic diagram and a photo of an experimental installation. To control the electric motor of the experimental installation, a mathematical model was developed that takes into account the electric motor speed. A second-order mathematical model was used as a mathematical framework for processing experimental data, constructing response surfaces and regression equations. The experiment assumed a fi ve-fold weight measurement of the dosing error of feed additives for each type of the screw design.
