“…Evaluated (Mylostyvyi et al, 2019 b) the state of the microclimate in one of the frame-type buildings with a roof made of sandwich panels (48°34′03.1″N, 34°54′47.0″E) located along the longitudinal axis from the northeast to southwest relative to the cardinal points in the summer season (at a temperature of +16.6 to +37.2 °C). Remote sensors were mounted at a height of 50 cm from the floor in the central and extreme boxes of the section.…”

Modern non-insulated barns (NB) for free-stall housing of dairy cows differ from traditional (typical) capital buildings. The formation of the microclimate in such farms is significantly dependent on the state of the environment and their design features. The aim of the work was to give a review of the literature and the results of our own research on creating comfortable conditions for dairy cows in the NB. Our studies indicate the heterogeneity of the microclimate formation in different parts of the NB, which was largely due to the state of the external environment. The use of only natural ventilation through open side curtains and light ridges, as well as additional mechanical ventilation (due to horizontal axial fans) cannot always provide comfortable conditions for animals, especially in hot periods of the year. The literature analysis showed that this can be caused by factors affecting the formation and movement of air masses in the building itself (depending on the number of animals, the condition of the litter, the operation of internal equipment, including space-planning and design features, type and quality of materials of enclosing structures) as well as the weather conditions outside buildings (temperature, humidity, wind strength and also relief). Investigations related to remote methods of microclimate control (using appropriate portable devices) and identification of (critical) control points of deterioration of the air environment in NBs will be promising. Monitoring of them will allow timely to adopt the necessary management decisions for ensuring the comfort of dairy cows in extreme weather conditions. Climate prediction methods based on meteorological data in the area of the NB location and the development of intelligent ventilation systems using mathematical modeling that take into account the behavioral and physiological responses of animals to environmental changes will be especially in demand.

The concept of biotechnical systems belongs to the class of human-machine systems or human–machine–plant systems, human–machine–animal systems. The latter relate to agriculture and the livestock industry. In agricultural production, biotechnical systems have the properties of bimodality, when there are two or more biological objects, a person as a managing operator and a service object (plants, animals).(Research purpose) The research purpose is in analyzing trends in the development of biomachine and technical systems in order to further intellectualize and digitalize agricultural production.(Materials and methods) There are two approaches in the study of human-machine systems: anthropocentric and machine-centric; the first one assigns a crucial role to the person, the second one – to the machine.(Results and discussion) The article presents the functionality of the Human and Machine subsystems. Part of the functions of the Human operator will gradually be transferred to the Machine, and the Human operator will be transformed into a human Expert and a human User. The article presents a scheme for an intelligent biotechnical system in animal husbandry, and determines the coefficients of adaptation of local automated and robotic biotechnical systems to biological objects. Authors have created a scheme for the functioning of local biotechnical systems in a partially autonomous multi-agent control mode, and identifies criteria for evaluating the functioning of local biotechnical systems.(Conclusions) We need to strengthen the Machine factor on the basis of developing machine-centric models and convert complex three-tier system of biotech in animal husbandry in two-tier with the polarization of the human Expert, human User and Machine–Animal subsystems. The latter absorbs more and more intelligent functions that are passed by a Man, for which it retained control, coordination and management of the entire system.
