Assessment of microclimate and gaseous pollutants in dairy and pig sheds in an organised farm

The article is devoted to the topical problem of rational use of energy and nutrient content of feed in obtaining livestock products (milk) from cows by shifting the energy balance of the animal’s body towards “productive energy”, i.e. the synthesis of fat and proteins. The authors would like to point out that one of the main factors influencing fluctuations in the energy balance of an animal are microclimate parameters, as the deviation of the microclimate parameters from the established optimal limits leads to a reduction in milk yields by 10 to 20%. Therefore, the aim of our work is to develop an energy-saving technology for the formation of optimal microclimate in livestock facilities using air conditioning systems, which can regulate most of the parameters of the microclimate inside them, namely: temperature, relative humidity and internal air velocity, concentration of harmful gases (carbon dioxide, ammonia, and hydrogen sulfide), dust and microorganisms. The presence of the mode enabling recirculation air purification allows to save heat energy and energy coming with feed by up to 50% compared with typical microclimate systems. To this end, we have systematized separate data from scientific researches done by various scientists in the fields of animal hygiene and veterinary medicine and obtained dependencies of influence of microclimate parameters (temperature, relative humidity, internal air velocity) on the productivity of animals (cows) and feed consumption.

The article presents the livestock structural and hardware implementations, the element base of digital intelligent microclimate control’s systems, the tasks must be solved in the light of microclimate quality imposed by livestock production modern technologies’ requirements are formulated. It is shown that the microclimate quality by changing of heating (cooling) power and air exchange equipment based on air environment’s temperature, humidity, and carbon dioxide content’s measurements is provided. An animals’ premises microclimate parameters’ automatic discrete-analog-digital control has been developed. The livestock farm premises’ microclimate system controlling hardware implementation’s scheme, including two levels: an electronic computer (farm), controllers with control and measuring devices, an interface, and executive devices (premises) has been developed. The information flows in the control system are determined: tasks are sent from the computer to the controllers for the current values of temperature, humidity, air pollution in the rooms, controllers in communication with measuring devices (radio channel), ventilation, heating (cooling) control devices. An example of the optimal microclimate control system’s effectiveness on 1300 heads of pigsty-feedlot is shown.
