The research is aimed at profound study of the influence of the "machine" factor (M) in the "human-machineanimal" system ("H-M-A") with the detailed description of the functions performed by "M", taking into account the convey of "M" control and control functions from the subsystems "human-operator" (HO) and "animal" (A). The paper presents the scheme of transformation and expansion of machine functionality in a biotechnical system; mathematical modeling of the dependence of technological signals controlled by the functions of local biotechnological systems (LBTS); mathematical model of diagnostic signals about the corresponding parameters of technical blocks of LBTS. Algorithmization and digitalization of processes on a dairy farm include an extended list of control indicators: technological signals, diagnostic signals and "alarm" signals presented in the article in matrix form. Monitoring the parameters of the most important subsystem "M" of the complex biotechnical system "H-M-A" of a dairy farm provides an increase in the level of automation, digitalization and intellectualization of the corresponding processes of milking, feeding, manure removal and others which creates prerequisites for improving their work and servicing animals as well as increasing the level of autonomy of their functioning. The development of the "machine" factor of the system is advisable on the basis of the machine-centric model of the LBTS, which will gradually expand its functions due to the transferred control and management functions from the corresponding subsystems "HO" and "A". The control parameters are determined at the characteristic reference points of the quarter curves of milk output for the development of refined algorithms for controlling the milking processes of individual udder shares in automated and robotic milking machines of the new generation. A graphical and numerical model of a wheeled feed-pusher robot in the Matlab/Simulink environment is shown. The created mathematical model of motion control by a wheeled feed-pusher robot provides effective interaction of the positioning system and the wheeedl robot drive in digital of autonomous movement.

The article introduces the concept of «smart» farm as a tool for decision making support and provides the requirements necessary for its functioning. The aim of the research is the development of the concept of “smart” farm using modern system approach and intellectual technologies of biomachine systems. The conditions influencing the “smart” dairy farm operation according to V.P. Goryachkin, P.K. Anokhin and YA. Gulsen are outlined. The structure of management on a dairy farm in the form of the expanded ergatic system is presented. The problems associated with the uncertainty of subjective nature (lack of sufficient information) on the dairy farm are formulated and the ways of solving these problems are given. The priority areas and projects for the development of a «smart» dairy farm are outlined. They should provide reduction in labor intensity of all operations on a farm and 2-2.5 times increase in productive longevity of cows. The technology of optimization of feeding processes on the farm leading to 1.5-2 times rise in digestibility as compared to traditional methods is introduced. A non-contact hardware and software complex of video and digital identification of udder and joint diseases in cows is shown. It should lead to decrease in mastitis disease rate in cows.

The paper presents a mathematical modeling of the process of movement of milk in the pipe in the formation of the slug flow. The estimation of the degree of destabilization of milk fat from hydromechanical factors is presented, which is 6-10% for the obtained values of the flow rate. Experimental and calculated data show that with the slug flow of transporting milk from the milking unit collector to the upper milk line, the slug speed reaches significant values exceeding 10 m/s, and the acceleration at the border of sections I and II is 150 m/s2. All this creates prerequisites for intensive hydromechanical effects on the dispersed composition of fat in milk.
